OPTIONS
The Delphi series DNL10, 8.3~14V input, single output, 20A non-isolated
point of load DC/DC converter in surface mounted package is the latest
offering from a world leader in power systems technology and
manufacturing ― Delta Electronics, Inc. The DNL10 series provides a
programmable output voltage from 0.75V to 5.0V through an external
trimming resistor. The DNL10 converters have flexible and programmable
tracking and sequencing features to enable a variety of sequencing and
tracking between several point of load power modules. This product
family is available in a surface mount or SIP package and provides up to
20A of output current in an industry standard footprint and pinout. With
creative design technology and optimization of component placement,
these converters possess outstanding electrical and thermal performance
and extremely high reliability under highly stressful operating conditions.

FEATURES DESCRIPTIONS
DESIGN CONSIDERATIONS (CON.)
Remote On/Off
The power module should be connected to a low
ac-impedance input source. Highly inductive source
impedances can affect the stability of the module. An
input capacitance must be placed close to the modules
input pins to filter ripple current and ensure module
stability in the presence of inductive traces that supply
the input voltage to the module.
The DNL series power modules have an On/Off pin for
remote On/Off operation. Both positive and negative
On/Off logic options are available in the DNL series
power modules.
For positive logic module, connect an open collector
(NPN) transistor or open drain (N channel) MOSFET
between the On/Off pin and the GND pin (see figure 32).
Positive logic On/Off signal turns the module ON during
the logic high and turns the module OFF during the logic
low. When the positive On/Off function is not used, leave
the pin floating or tie to Vin (module will be On).
Safety Considerations
For safety-agency approval the power module must be
installed in compliance with the spacing and separation
requirements of the end-use safety agency standards.
For the converter output to be considered meeting the
requirements of safety extra-low voltage (SELV), the
input must meet SELV requirements. The power module
has extra-low voltage (ELV) outputs when all inputs are
ELV.
For negative logic module, the On/Off pin is pulled high
with an external pull-up resistor (see figure 33) Negative
logic On/Off signal turns the module OFF during logic
high and turns the module ON during logic low. If the
negative On/Off function is not used, leave the pin
floating or tie to GND. (module will be On)
The input to these units is to be provided with a
maximum 15A of glass type fast-acting fuse in the
ungrounded lead.

Over-Current Protection
To provide protection in an output over load fault
condition, the unit is equipped with internal over-current
protection. When the over-current protection is
triggered, the unit enters hiccup mode. The units
operate normally once the fault condition is removed.
DS_DNL10SMD_07182012

FEATURES DESCRIPTIONS (CON.)
For example, to program the output voltage of the DNL
module to 3.3Vdc, Rtrim is calculated as follows:
Over-Temperature Protection
10500
The over-temperature protection consists of circuitry
that provides protection from thermal damage. If the
temperature exceeds the over-temperature threshold
the module will shut down. The module will try to restart
after shutdown. If the over-temperature condition still
exists during restart, the module will shut down again.
This restart trial will continue until the temperature is
within specification
Rtrim :=
− 1000 ⋅Ω
2.5475
Rtrim = 3.122 kΩ
DNL can also be programmed by applying a voltage
between the TRIM and GND pins (Figure 36). The
following equation can be used to determine the value of
Vtrim needed for a desired output voltage Vo:
Remote Sense
(
)
Vtrim := 0.7 − Vo − 0.7525 ⋅0.0667
The DNL provide Vo remote sensing to achieve proper
regulation at the load points and reduce effects of
distribution losses on output line. In the event of an
open remote sense line, the module shall maintain local
sense regulation through an internal resistor. The
module shall correct for a total of 0.1V of loss. The
remote sense line impedance shall be < 10Ω.
Vtrim is the external voltage in V

Output Voltage Programming
Figure 32: Circuit configuration for programming output voltage

The output voltage of the DNL can be programmed to
any voltage between 0.75Vdc and 5.0Vdc by
connecting one resistor (shown as Rtrim in Figure 35)
between the TRIM and GND pins of the module.
Without this external resistor, the output voltage of the
module is 0.7525 Vdc. To calculate the value of the
resistor Rtrim for a particular output voltage Vo, please
use the following equation:

Rtrim :=
− 1000 ⋅Ω

FEATURE DESCRIPTIONS (CON.)
The amount of power delivered by the module is the
voltage at the output terminals multiplied by the output
current. When using the trim feature, the output voltage
of the module can be increased, which at the same
output current would increase the power output of the
module. Care should be taken to ensure that the
maximum output power of the module must not exceed
the maximum rated power (Vo.set x Io.max ≤ P max).
Table 1 provides Rtrim values required for some common
output voltages, while Table 2 provides values of external
voltage source, Vtrim, for the same common output
voltages. By using a 1% tolerance trim resistor, set point
tolerance of ±2% can be achieved as specified in the
electrical specification.

Output voltage margining can be implemented in the DNL
modules by connecting a resistor, R margin-up, from the Trim
pin to the ground pin for margining-up the output voltage
and by connecting a resistor, Rmargin-down, from the Trim pin
to the output pin for margining-down. Figure 37 shows
the circuit configuration for output voltage margining. If
unused, leave the trim pin unconnected. A calculation
tool is available from the evaluation procedure, which
computes the values of Rmargin-up and Rmargin-down for a
specific output voltage and margin percentage.

Voltage Tracking
The DNL family was designed for applications that have
output voltage tracking requirements during power-up
and power-down. The devices have a TRACK pin to
implement three types of tracking method: sequential
start-up, simultaneous and ratio-metric. TRACK simplifies
the task of supply voltage tracking in a power system by
enabling modules to track each other, or any external
voltage, during power-up and power-down.
By connecting multiple modules together, customers can
get multiple modules to track their output voltages to the
voltage applied on the TRACK pin.
DS_DNL10SMD_07182012

FEATURE DESCRIPTIONS (CON.)
The output voltage tracking feature (Figure 35 to Figure
37) is achieved according to the different external
connections. If the tracking feature is not used, the
TRACK pin of the module can be left unconnected or tied
to Vin.
Sequential Start-up
Sequential start-up (Figure 35) is implemented by placing
an On/Off control circuit between VoPS1 and the On/Off pin
of PS2.

For proper voltage tracking, input voltage of the tracking
power module must be applied in advance, and the

The simultaneous tracking can be accomplished by
connecting VoPS1 to the TRACK pin of PS2. Please note
the voltage apply to TRACK pin needs to always higher

THERMAL CONSIDERATIONS
FEATURE DESCRIPTIONS (CON.)
Thermal management is an important part of the system
design. To ensure proper, reliable operation, sufficient
cooling of the power module is needed over the entire
temperature range of the module. Convection cooling is
usually the dominant mode of heat transfer.
Ratio-Metric
Ratio–metric (Figure 37) is implemented by placing the
voltage divider on the TRACK pin that comprises R1 and
R2, to create a proportional voltage with VoPS1 to the
Track pin of PS2.
Hence, the choice of equipment to characterize the
thermal performance of the power module is a wind
tunnel.
For Ratio-Metric applications that need the outputs of
PS1 and PS2 reach the regulation set point at the same
time
Thermal Testing Setup
The following equation can be used to calculate the value
of R1 and R2.
Delta’s DC/DC power modules are characterized in
heated vertical wind tunnels that simulate the thermal
environments encountered in most electronics
equipment. This type of equipment commonly uses
vertically mounted circuit cards in cabinet racks in which
the power modules are mounted.
The suggested value of R2 is 10kΩ.

Thermal Derating
Heat can be removed by increasing airflow over the
module. To enhance system reliability, the power
module should always be operated below the maximum
operating temperature. If the temperature exceeds the
maximum module temperature, reliability of the unit may
be affected.
