PRODUCT OVERVIEW
ꢀ
Step-down buck regulators for new
distributed 12V power architectures
LSM Series D12 SMTs (surface-mount pack-
ages) are ideal building blocks for emerging,
on-board power-distribution schemes in which
isolated 12V buses deliver power to any num-
ber of non-isolated, step-down buck regulators.
LSM D12 DC/DC’s accept a 12V input (10V to
14V input range) and convert it, with the highest
efficiency in the smallest space, to a 0.75, 1,
1.2, 1.5, 1.8, 2, 2.5, 3.3 or 5 Volt output fully
rated at 16 Amps.
LSM D12’s are ideal point-of-use/load power
processors. They typically require no external
components. Their surface-mount packages
occupy a mere 1.3" x 0.53" (33.0 x 13.5mm),
and are only 0.34 inches (8.6mm) high.
The LSM’s best-in-class power density
noise (50mVp-p typ.), tight line/load regulation
( 0.1ꢀ/ 0.25ꢀ max.), quick step response
(100μsec), stable no-load operation, and no
output reverse conduction.
The fully functional LSM’s feature output
overcurrent detection, continuous short-circuit
protection, over-temperature protection, a
remote on/off control pin (pull low to disable),
an output-voltage trim function, and a sense
pin. High efficiency enables the LSM D12’s to
deliver rated output currents of 16 Amps at
ambient temperatures to +65°C with 100 lfm
air flow.
If your new system boards call for multiple
supply voltages, check out the economics of
on-board 12V distributed power. If you don’t
need to pay for multiple isolation barriers,
Murata Power Solutions’ non-isolated LSM D12
SMTs will save you money.

All models in the LSM D12 Series are tested and specified with external 22μF
tantalum input and output capacitors. These capacitors are necessary to
accommodate our test equipment and may not be required to achieve desired
performance in your application. The LSM D12's are designed with high-
quality, high-performance internal I/O caps, and will operate within spec in
most applications with no additional external components.

External input capacitors serve primarily as energy-storage devices. They
minimize high-frequency variations in input voltage (usually caused by IR drops
in conductors leading to the DC/DC) as the switching converter draws pulses of
current. Input capacitors should be selected for bulk capacitance (at appropri-
ate frequencies), low ESR, and high rms-ripple-current ratings. The switching
nature of modern DC/DCs requires that the dc input voltage source have low
ac impedance at the frequencies of interest. Highly inductive source imped-
ances can greatly affect system stability. Your specific system configuration
may necessitate additional considerations.

LSM D12 SMT's are non-isolated DC/DC converters. In general, all DC/DC's
must be installed, including considerations for I/O voltages and spacing/sepa-
ration requirements, in compliance with relevant safety-agency specifications
(usually UL/IEC/EN60950-1).

Input Overvoltage and Reverse-Polarity Protection
Figure 2. Measuring Input Ripple Current
LSM D12 SMT Series DC/DC's do not incorporate either input overvoltage or
input reverse-polarity protection. Input voltages in excess of the specified
absolute maximum ratings and input polarity reversals of longer than "instan-
taneous" duration can cause permanent damage to these devices.
Output ripple/noise (also referred to as periodic and random deviations or
PARD) may be reduced below specified limits with the installation of additional
external output capacitors. Output capacitors function as true filter elements
and should be selected for bulk capacitance, low ESR, and appropriate fre-
quency response. Any scope measurements of PARD should be made directly
at the DC/DC output pins with scope probe ground less than 0.5" in length.
Start-Up Time
The VIN to VOUT Start-Up Time is the interval between the time at which a ramp-
ing input voltage crosses the lower limit of the specified input voltage range
(10 Volts) and the fully loaded output voltage enters and remains within its
specified accuracy band. Actual measured times will vary with input source
impedance, external input capacitance, and the slew rate and final value of the
input voltage as it appears to the converter.

The On/Off to VOUT Start-Up Time assumes the converter is turned off via the

specified accuracy band. See Typical Performance Curves.

Remote Sense
LSM D12 SMT Series DC/DC converters offer an output sense function on pin 6.
The sense function enables point-of-use regulation for overcoming moderate
IR drops in conductors and/or cabling. Since these are non-isolated devices
whose inputs and outputs usually share the same ground plane, sense is
provided only for the +Output.

C2 = 22µF TANTALUM
LOAD 2-3 INCHES (51-76mm) FROM MODULE
Figure 3. Measuring Input Ripple Current
The remote sense line is part of the feedback control loop regulating the DC/
DC converter’s output. The sense line carries very little current and conse-
quently requires a minimal cross-sectional-area conductor. As such, it is not
a low-impedance point and must be treated with care in layout and cabling.
Sense lines should be run adjacent to signals (preferably ground), and in
cable and/or discrete-wiring applications, twisted-pair or similar techniques
should be used. To prevent high frequency voltage differences between VOUT
and Sense, we recommend installation of a 1000pF capacitor close to the
converter.
All external capacitors should have appropriate voltage ratings and be
located as close to the converters as possible. Temperature variations for all
relevant parameters should be taken into consideration.
The most effective combination of external I/O capacitors will be a func-
tion of your line voltage and source impedance, as well as your particular load
and layout conditions. Our Applications Engineers can recommend potential
solutions and discuss the possibility of our modifying a given device’s internal
filtering to meet your specific requirements. Contact our Applications Engineer-
ing Group for additional details.
The sense function is capable of compensating for voltage drops between
the +Output and +Sense pins that do not exceed 10ꢀ of VOUT.
Input Fusing
Most applications and or safety agencies require the installation of fuses at
the inputs of power conversion components. The LSM D12 Series are not
internally fused. Therefore, if input fusing is mandatory, either a normal-blow or
a fast-blow fuse with a value no greater than twice the maximum input current
should be installed within the ungrounded input path to the converter.
[VOUT(+) – Common] – [Sense(+) – Common] ≤ 10ꢀVOUT
Power derating (output current limiting) is based upon maximum output cur-
rent and voltage at the converter's output pins. Use of trim and sense functions
can cause the output voltage to increase, thereby increasing output power
beyond the LSM's specified rating. Therefore:
As a rule of thumb however, we recommend to use a normal-blow or
slow-blow fuse with a typical value of about twice the maximum input current,
calculated at low line with the converters minimum efficiency.

Non-Isolated, 13-80W SMT DC/DC Converters
Leaving the input of the on/off circuit closed during power-up will have the
output of the DC/DC converter disabled. When the input to the external open
collector is pulled high, the DC/DC converter's output will be enabled.
The internal 10.5Ω resistor between +Sense and +Output (see Figure 1)
serves to protect the sense function by limiting the output current flowing
through the sense line if the main output is disconnected. It also prevents
output voltage runaway if the sense connection is disconnected.
Output Overvoltage Protection
Note: If the sense function is not used for remote regulation, +Sense (pin 6)
must be tied to +Output (pin 4) at the DC/DC converter pins.
LSM D12 SMT Series DC/DC converters do not incorporate output overvoltage
protection. In the extremely rare situation in which the device’s feedback loop
is broken, the output voltage may run to excessively high levels (VOUT = VIN). If it
is absolutely imperative that you protect your load against any and all possible
overvoltage situations, voltage limiting circuitry must be provided external to
the power converter.
On/Off Control
The On/Off Control pin may be used for remote on/off operation. LSM D12
Series DC/DC converters are designed so that they are enabled when the con-
trol pin is left open (open collector) and disabled when the control pin is pulled
low (to less than +0.4V relative to Common). As shown in Figure 4, all models
have an internal pull-up current source to VIN (+Input).
Output Overcurrent Detection
Overloading the power converter's output for an extended time will invariably
cause internal component temperatures to exceed their maximum ratings and
eventually lead to component failure. High-current-carrying components such
as inductors, FET's and diodes are at the highest risk. LSM D12 SMT Series
DC/DC converters incorporate an output overcurrent detection and shutdown
function that serves to protect both the power converter and its load.

If the output current exceeds it maximum rating by typically 70ꢀ (27 Amps)
or if the output voltage drops to less than 98ꢀ of it original value, the LSM
D12's internal overcurrent-detection circuitry immediately turns off the con-
verter, which then goes into a "hiccup" mode. While hiccupping, the converter
will continuously attempt to restart itself, go into overcurrent, and then shut
down. Under these conditions, the average output current will be approximately
400mA, and the average input current will be approximately 40mA. Once the
output short is removed, the converter will automatically restart itself.

Figure 4. On/Off Control Using An External Open Collector Driver
Dynamic control of the on/off function is best accomplished with a
mechanical relay or open-collector/open-drain drive circuit (optically isolated if
appropriate). The drive circuit should be able to sink appropriate current when
activated and withstand appropriate voltage when deactivated.
Output Voltage Trimming
Allowable trim ranges for each model in the LSM D12 SMT Series are 10ꢀ.
Trimming is accomplished with either a trimpot or a single fixed resistor. The
trimpot should be connected between +Output and Common with its wiper
connected to the Trim pin as shown in Figure 6 below.
Applying an external voltage to the On/Off Control pin when no input power
is applied to the converter can cause permanent damage to the converter. The
on/off control function, however, is designed such that the converter can be
disabled (control pin pulled low) while input voltage is ramping up and then
"released" once the input has stabilized (see also power-up sequencing).

If a controlled start-up of one or more LSM D12 Series DC/DC converters
is required, or if several output voltages need to be powered-up in a given
sequence, the On/Off control pin can be driven with an external open collector
device as per Figure 5.

Figure 6.Trim Connections Using a Trimpot
A trimpot can be used to determine the value of a single fixed resistor
which can then be connected, as shown in Figure 7, between the Trim pin and
+Output to trim down the output voltage, or between the Trim pin and Common
to trim up the output voltage. Fixed resistors should have absolute TCR’s less
than 100ppm/°C to ensure stability.

TRIM
This version of the LSM 16A series offers a special output voltage trimming
feature which is fully compatible with competitive units. The output voltage
may be varied from 0.75 to 5 Volts using a single external trim-up resistor con-
nected from the Trim input to Output Common. If no trim resistor is attached
(Trim pin open), the output is 0.7525 Volts.

The trim may also be adjusted using an external reference voltage con-
nected to the Trim input.
COMMON
As with other trim adjustments, use a 1ꢀ metal film precision resistor with
low temperature coefficient ( 100 ppm/°C or less) mounted close to the con-
verter with short leads. Also be aware that the output accuracy is 2ꢀ (typical)
therefore you may need to vary this resistance slightly to achieve your desired
output setting.
Figure 7.Trim Connections Using Fixed Resistors
The equations below can be starting points for selecting specific trim-resistor
values. Recall, untrimmed devices are guaranteed to be 1.25ꢀ accurate.
Adjustment beyond the specified 10ꢀ adjustment range is not recom-
mended. When using trim in combination with Remote Sense, the maximum
rated power must not be exceeded (see Remote Sense).
The resistor trim up equation for the LSM-T/16-D12 is as follows:

The LSM-T/16-D12 may also be trimmed using an external voltage applied
between the Trim Input and Output Common. Be aware that the internal “load”
impedance looking into trim pin is approximately 5kΩ. Therefore, you may
have to compensate for this in the source resistance of your external voltage
reference.
The equation for this voltage adjustment is:
VTRIM = 0.7 – (0.0667 × (VO – 0.7525))
Note: Resistor values are in kΩ. Accuracy of adjustment is subject
to tolerances of resistors and factory-adjusted, initial output accuracy.

LSM-16A D12 Models
Non-Isolated, 13-80W SMT DC/DC Converters
Output Reverse Conduction
The highest temperatures in LSM D12 SMTs occur at their output inductor,
whose heat is generated primarily by I2R losses. The derating curves were
developed using thermocouples to monitor the inductor temperature and vary-
ing the load to keep that temperature below +110°C under the assorted condi-
tions of air flow and air temperature. Once the temperature exceeds +115°C
(approx.), the thermal protection will disable the converter. Automatic restart
occurs after the temperature has dropped below +110°C.
Many DC/DCs using synchronous rectification suffer from Output Reverse
Conduction. If those devices have a voltage applied across their output before
a voltage is applied to their input (this typically occurs when another power
supply starts before them in a power-sequenced application), they will either
fail to start or self destruct. In both cases, the cause is the “freewheeling” or
“catch” FET biasing itself on and effectively becoming a short circuit.
As you may deduce from the derating curves and observe in the efficiency
curves on the following pages, LSM D12 SMT's maintain virtually constant
efficiency from half to full load, and consequently deliver very impressive
temperature performance even if operating at full load.
LSM D12 SMT DC/DC converters do not suffer from Output Reverse Conduc-
tion. They employ proprietary gate drive circuitry that makes them immune to
applied output voltages.
Thermal Considerations and Thermal Protection
Lastly, when LSM D12 SMT's are installed in system boards, they are
obviously subject to numerous factors and tolerances not taken into account
here. If you are attempting to extract the most current out of these units under
demanding temperature conditions, we advise you to monitor the output-
inductor temperature to ensure it remains below +110°C at all times.
The typical output-current thermal-derating curves shown below enable
designers to determine how much current they can reliably derive from each
model of the LSM D12 SMTs under known ambient-temperature and air-flow
conditions. Similarly, the curves indicate how much air flow is required to reli-
ably deliver a specific output current at known temperatures.

Non-Isolated, 13-80W SMT DC/DC Converters
Tape & Reel Surface Mount Package
MPS is not exempted from the Laws of Physics, and we do not have magic
solders no one else has. Nevertheless, we have a simple and practical, straight-
forward approach that works. We assemble our LSM SMT DC/DCs using a
high-temperature (+216°C), lead-free alloy (Sn96.2ꢀ, Ag2.5ꢀ, Cu0.8ꢀ,
Sb0.5ꢀ). The LSM design ensures co-planarity to within 0.004 inches (100μm)
of the unit’s copper leads. These leads are gold-plated with a nickel underplate.
See Mechanical Data for additional information.
Murata Power Solutions’ LSM series DC/DC converters are the only higher-
current (16A) SMT DC/DCs that can be automatically “pick-and-placed” using
standard vacuum-pickup equipment (nozzle size and style, vacuum pressure
and placement speed may need to be optimized for automated pick and place)
and subsequently reflowed using high-temperature, lead-free solder.
Virtually all SMT DC/DCs today are unprotected “open-frame” devices
assembled by their vendors with high-temperature solder (usually Sn96.5/
Ag3.5 with a melting point of +221°C) so that you may attach them to your
board using low-temperature solder (usually Sn63/Pb37 with a melting point
of +183°C). Conceptually straightforward, this “stepped” solder approach has
its limitations, and it is clearly out of step with an industry trending toward
the broad use of lead-free solders. Are you to experiment and develop reflow
profiles from other vendors that ensure the components on those DC/DC never
exceed 215–216°C? If those components get too hot, “double-reflow” could
compromise the reliability of their solder joints. Virtually all these devices
demand you “cool down” the Sn63 profile you are likely using today.
The disposable heat shield (patent pending), which has a cutaway expos-
ing the package leads, provides thermal insulation to internal components
during reflow and its smooth surface ideally doubles as the vacuum pick-up
location also. The insulation properties of the heat shield are so effective that
temperature differentials as high as 50°C develop inside-to-outside the shield.
Oven temperature profiles with peaks of 250–260°C and dwell times exceed-
ing 2 minutes above 221°C (the melting point of Sn96.5/Ag3.5) are easily
achieved.
