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 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.

Vtrim = 0.7 − 0.1698 × (Vo − 0.7525)
Over-Temperature Protection
For example, to program the output voltage of a DNL
module to 3.3 Vdc, Vtrim is calculated as follows
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

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:
DS_DNM04SIP10_05292006
Table 1 provides Rtrim values required for some common
output voltages, while Table 2 provides value 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.

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
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.
The DNL family has 3 different option codes for TRACK
function.
Option code A: 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. (Figure 41)
Option code B: No TRACK function
Option code C: Implementation of advanced power
tracking techniques is based on connecting the power
good signal or selecting proper value for external
resistor R1 (Figure 40 to Figure 43).

Voltage Tracking
The DNM/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, ratio-metric and simultaneous. 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.

Sequential start-up (Figure 40) is implemented by
connecting the power good pin of PS1 to the TRACK pin
of PS2 with a resistor–capacitor (RC) circuit. Suggest to
use 1µF ceramic capacitor and 2KΩ resistor here.
Besides, this configuration requires PS1 to have a power
good function.

Ratio–metric is implemented by selecting the resistor
values of the voltage divider on the TRACK pin. To simplify
the tracking design, set initial value of R2 equal to 20KΩ at
internal circuit and adjust resistor R1 for the different
tracking method. The circuit diagram of Ratio-Metric is the
same as Simultaneous when VoPS2 tracks the VoPS1.
For Ratio-Metric applications that need the outputs of PS1
and PS2 go to the regulation set point at the same time
(Figure 43), use the following equation (1) to calculate the
value of resistor R1,

Simultaneous
Simultaneous tracking (Figure 41) is implemented by
using a voltage divider around the TRACK pin. The
objective is to minimize the voltage difference between
the power supply outputs during power up and down.
For type A (DNX0A0XXXX A), the simultaneous tracking
can be accomplished by connecting VoPS1 to the TRACK
pin of PS2 where the voltage divider is inside the PS2.

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. 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.
