Note: Input reflected-ripple current is measured with a

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 20 shows the input ripple voltage
(mVp-p) for various output models using 4x47 uF low
ESR tantalum capacitors (SANYO P/N:16TPB470M,

ceramic capacitors (TDK P/N:C3225X7S1C226MT,

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 of glass type fast-acting fuse in the
ungrounded lead.
The DNM 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 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 21).
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 resistor (see figure 22) 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_DNM10SMD10_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
Remote Sense
The DNM 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.

For example, to program the output voltage of the DNM
module to 3.3Vdc, Rtrim is calculated as follows:
⎛ 10500 − 1000 ⎞ ⋅ Ω
⎟
⎝ 2.5475
⎠
Rtrim := ⎜
Rtrim = 3.122 kΩ
DNM can also be programmed by applying a voltage
between the TRIM and GND pins (Figure 25). The
following equation can be used to determine the value of
Vtrim needed for a desired output voltage Vo:
Vtrim := 0.7 − ⎡⎣( Vo − 0.7525) ⋅ 0.0667⎤⎦
Vtrim is the external voltage in V
Vo is the desired output voltage
For example, to program the output voltage of a DNM
module to 3.3 Vdc, Vtrim is calculated as follows
Vtrim := 0.7 − ( 2.5475 ⋅ 0.0667)
Vtrim = 0.530V

Output Voltage Programming
The output voltage of the DNM can be programmed to
any voltage between 0.75Vdc and 5.0Vdc by connecting
one resistor (shown as Rtrim in Figure 24) 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.)
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.

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
Output voltage margining can be implemented in the
DNM 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 26
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 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,
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_DNM10SMD10_03062009

FEATURE DESCRIPTIONS (CON.)
The output voltage tracking feature (Figure 27 to Figure
29) 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 27) is implemented by placing
an On/Off control circuit between VoPS1 and the On/Off pin
of PS2.
PS1
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)

Simultaneous tracking (Figure 28) is implemented by
using the TRACK pin. The objective is to minimize the
voltage difference between the power supply outputs
during power up and down.
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
than the VoPS2 set point voltage.

Ratio-Metric
Ratio–metric (Figure 29) 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.
For Ratio-Metric applications that need the outputs of PS1
and PS2 reach the regulation set point at the same time
The following equation can be used to calculate the value
of R1 and R2.

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’’).

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.
