DESIGN CONSIDERATIONS
Input Source Impedance
VI(+)
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 F low ESR tantalum capacitor (KEMET p/n: T491D107M016AS, AVX p/n: TAJD107M106R, or equivalent) in parallel with 47 F ceramic capacitor (TDK p/n:C5750X7R1C476M or equivalent). Figure 33 shows much lower input voltage ripple when input capacitance is increased to 400 F (4 x 100 F) tantalum capacitors in parallel with 94 F (2 x 47 F) ceramic capacitor. The input capacitance should be able to handle an AC ripple current of at least:

DESIGN CONSIDERATIONS (CON.)
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.
FEATURES DESCRIPTIONS
Remote On/Off
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). 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)

ION/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 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.
DS_DNS04SMD6A_10202006 9
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 x (Vo - 0.7525)
For example, to program the output voltage of a DNS module to 3.3 Vdc, Vtrim is calculated as follows
Vtrim = 0.7 - 0.1698 x (3.3 - 0.7525) = 0.267V

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. Table 1

Output Voltage Programming
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:
21070 Rtrim = - 5110 Vo - 0.7525
For example, to program the output voltage of the DNS module to 1.8Vdc, Rtrim is calculated as follows:
Table 2
Vo(V) 0.7525 1.2 1.5 1.8 2.5 3.3 Vtrim(V) Open 0.624 0.573 0.522 0.403 0.267
21070 Rtrim = - 5110 = 15K 1.8 - 0.7525
DNS 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_DNS04SMD6A_10202006

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). 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)
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. By connecting multiple modules together, customers can get multiple modules to track their output voltages to the voltage applied on the TRACK pin. DS_DNS04SMD6A_10202006 11
Figure 42: Ratio-metric
FEATURE DESCRIPTIONS (CON.)
Sequential Start-up
Sequential start-up (Figure 40) is implemented by placing an On/Off control circuit between VoPS1 and the On/Off pin of PS2.
Ratio-Metric
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. For Ratio-Metric applications that need the outputs of PS1 and PS2 reach the regulation set point at the same time.

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 CURVES
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.
