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 200 µF(2 x100uF) 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.
Note: Input reflected-ripple current is measured with a
simulated source inductance. Current is measured at
the input of the module.
The input capacitance should be able to handle an AC
ripple current of at least:

DESIGN CONSIDERATIONS (CON.)
FEATURES DESCRIPTIONS
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.
Remote On/Off
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.
The input to these units is to be provided with a
maximum 15A time-delay fuse in the ungrounded lead.
The DNM/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 DNM/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 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).
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)

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_DNM04SMD10_03062009

FEATURES DESCRIPTIONS (CON.)
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
Vtrim = 0.7 − 0.1698 × (Vo − 0.7525)
For example, to program the output voltage of a DNL
module to 3.3 Vdc, Vtrim is calculated as follows
Vtrim = 0.7 − 0.1698 × (3.3 − 0.7525) = 0.267V

Output Voltage Programming
The output voltage of the DNM/DNL 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:
⎡ 21070
⎤
Rtrim = ⎢
− 5110⎥ Ω
⎣Vo − 0.7525
⎦
For example, to program the output voltage of the DNL
module to 1.8Vdc, Rtrim is calculated as follows:
⎡ 21070
⎤
Rtrim = ⎢
− 5110⎥ Ω = 15KΩ
⎣1.8 − 0.7525
⎦
DNL can also be programmed by apply a voltage
between the TRIM and GND pins (Figure 38). The
following equation can be used to determine the value of
Vtrim needed for a desired output voltage Vo:

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).
Voltage Margining
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.
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)
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 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
Figure 41: Simultaneous
The DNM 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.

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.
The following figure shows the wind tunnel
characterization setup. The power module is 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’’).
Thermal Derating
Heat can be removed by increasing airflow over the
module. The module’s maximum hot spot temperature is
125°C. 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.
