DESIGN CONSIDERATIONS
TEST CONFIGURATIONS
Input Source Impedance
TO OSCILLOSCOPE
To maintain low noise and ripple at the input voltage, it is
critical to use low ESR capacitors at the input to the
module. Figure 32 shows the input ripple voltage (mVp-p)
for various output models using 2x100 µF low ESR
tantalum capacitor (KEMET p/n: T491D107M016AS,
AVX p/n: TAJD107M106R, or equivalent) in parallel with
47 µF ceramic capacitor (TDK p/n:C5750X7R1C476M or
equivalent). Figure 33 shows much lower input voltage
ripple when input capacitance is increased to 400 µF (4 x
100 µF) tantalum capacitors in parallel with 94 µF (2 x 47
µF) ceramic capacitor.

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 DNS 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 DNS 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 34).
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 5kΩ resistor (see figure 35).
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
6A time-delay 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.

FEATURES DESCRIPTIONS (CON.)
For example, to program the output voltage of a DNS
module to 3.3 Vdc, Vtrim is calculated as follows
Over-Temperature Protection
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.

The output voltage of the DNS can be programmed to any
voltage between 0.75Vdc and 3.3Vdc by connecting one
resistor (shown as Rtrim in Figure 37) 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:

FEATURE DESCRIPTIONS (CON.)
The output voltage tracking feature (Figure 40 to Figure
42) 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.
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).
For proper voltage tracking, input voltage of the tracking
power module must be applied in advance, and the
remote on/off pin has to be in turn-on status. (Negative
logic: Tied to GND or unconnected. Positive logic: Tied
to Vin or unconnected)
Voltage Margining
Output voltage margining can be implemented in the
DNS 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 39
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 R margin-up and
Rmargin-down for a specific output voltage and margin
percentage.

Voltage Tracking
The DNS 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.
Figure 42: Ratio-metric
By connecting multiple modules together, customers can
get multiple modules to track their output voltages to the
voltage applied on the TRACK pin.

FEATURE DESCRIPTIONS (CON.)
Ratio-Metric
Sequential Start-up
Ratio–metric (Figure 42) 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.
Sequential start-up (Figure 40) is implemented by placing
an On/Off control circuit between VoPS1 and the On/Off pin
of PS2.
For Ratio-Metric applications that need the outputs of PS1
and PS2 reach the regulation set point at the same time.

THERMAL CURVES
THERMAL CONSIDERATIONS
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.
Hence, the choice of equipment to characterize the
thermal performance of the power module is a wind
tunnel.
Thermal Testing Setup
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.

on a test PWB and is vertically positioned within the
wind tunnel. The height of this fan duct is constantly kept
at 25.4mm (1’’).
Natural
Convection
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.
