Current is measured at the input of the module. 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 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 6A time-delay fuse in the ungrounded lead. 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) Vo Vin ION/OFF On/Off RL Q1 GND Figure 34: Positive remote On/Off implementation Vo Vin Rpullup ION/OFF On/Off RL Q1 GND Figure 35: Negative remote On/Off implementation 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.) Vtrim = 0.7 − 0.1698 × (Vo − 0.7525) Over-Temperature Protection For example, to program the output voltage of a DNS 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. Vtrim = 0.7 − 0.1698 × (3.3 − 0.7525) = 0.267V Vo RLoad TRIM Rtrim GND Remote Sense Figure 37: Circuit configuration for programming output voltage The DNS 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 0.5V of loss. The remote sense line impedance shall be < 10Ω.

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 DNS module to 1.8Vdc, Rtrim is calculated as follows: ⎡ 21070 ⎤ Rtrim = ⎢ − 5110⎥ Ω = 15KΩ ⎣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 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.

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 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. Vin 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) PS1 PS1 PS2 PS2 Figure 40: Sequential Start-up Vo Rmargin-down PS1 PS1 PS2 PS2 Q1 On/Off Trim Rmargin-up Rtrim Q2 GND Figure 41: Simultaneous Figure 39: Circuit configuration for output voltage margining +∆V PS1 PS1 PS2 PS2 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. DS_DNS04SMD6A_10202006 11 FEATURE DESCRIPTIONS (CON.) Ratio-Metric 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 (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. PS1 PS2 Vin Vin VoPS1 VoPS2 R3 On/Off The following equation can be used to calculate the value of R1 and R2. The suggested value of R2 is 10kΩ.

The objective is to minimize the voltage difference between the power supply outputs during power up and down.

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’’).
