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 5kresistor (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.

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.

The following figure shows the wind tunnel

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.
