For the converter output to be considered meeting the

ELV.

Note: Input reflected-ripple current is measured with a
simulated source inductance. Current is
measured at the input of the module.
The input to these units is to be provided with a
maximum 50A of glass type fast-acting fuse in the
ungrounded lead.

Input Source Impedance
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.

For negative logic module, the On/Off pin is suggested
to be pulled high with an external pull-up resistor (see
figure 36). Negative logic On/Off signal turns the module
OFF during logic high and turns the module ON during

leave the pin floating or tie to GND. (module will be On)

The output voltage of the DNK can be programmed to
any voltage between 0.8Vdc and 5.5Vdc by connecting
one resistor (shown as Rtrim in Figure 38) between the
TRIM and GND pins of the module. Without this external
resistor, the output voltage of the module is 0.8 Vdc. To
calculate the value of the resistor Rtrim for a particular
output voltage Vo, please use the following equation:

Over-Current Protection
Rtrim :=

Vo − 0.80
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.

The over-temperature protection consists of circuitry

Table 1 provides Rtrim values required for some common
output voltages. By using a 0.5% tolerance trim resistor,
set point tolerance of ±1.5% can be achieved as specified
in the electrical specification.
Voltage Tracking
The DNK 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,
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.
Voltage Margining
Output voltage margining can be implemented in the
DNK 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.
The DNK family has option code A for TRACK function.
The output voltage Track characteristic can be achieved
when the output voltage of PS2 follows the output
voltage of PS1 on a volt-to-volt basis.

Simultaneous tracking (Figure 40) is implemented by

objective is to minimize the voltage difference between

For type A (DNX0A0XXXX A), the simultaneous tracking
can be accomplished by connecting VoPS1 to the TRACK

THERMAL CONSIDERATIONS
THERMAL CURVES
NTC RESISTOR
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.
AIRFLOW
Hence, the choice of equipment to characterize the
thermal performance of the power module is a wind
tunnel.
HOT SPOT
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.
