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. The models using 4x47 uF very low ESR ceramic capacitors (MURATA P/N: GRM32ER61C476ME15L, 47uF/16V or equivalent) for example.

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 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 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 32). 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 33) 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 RL On/Off GND Figure 29: Positive remote On/Off implementation Vo Vin Rpull-up ION/OFF On/Off RL GND Figure 30: 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_DNL10SMD_07182012 8 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 DNL 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. Distribution Losses Distribution Losses Vin Vo For example, to program the output voltage of the DNL module to 3.3Vdc, Rtrim is calculated as follows: 10500 − 1000 ⋅ Ω 2.5475 Rtrim := Rtrim = 3.122 kΩ DNL can also be programmed by applying a voltage between the TRIM and GND pins (Figure 36). 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 DNL module to 3.3 Vdc, Vtrim is calculated as follows Vtrim := 0.7 − ( 2.5475⋅ 0.0667) Vtrim = 0.530V Sense RL GND Distribution Losses Distribution Losses Figure 31: Effective circuit configuration for remote sense operation Output Voltage Programming The output voltage of the DNL can be programmed to any voltage between 0.75Vdc and 5.0Vdc by connecting one resistor (shown as Rtrim in Figure 35) 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: 10500 − 1000 ⋅ Ω Vo − 0.7525 Figure 32: Circuit configuration for programming output voltage using an external resistor Rtrim := Rtrim is the external resistor in Ω Vo is the desired output voltage DS_DNL10SMD_07182012 Figure 33: Circuit Configuration for programming output voltage using external voltage source 9 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.

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 37 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 Rmargin-up and Rmargin-down for a specific output voltage and margin percentage. Vin Vo Rmargin-down Q1 On/Off Trim Rmargin-up Rtrim Q2 GND Figure 34: Circuit configuration for output voltage margining Voltage Tracking The 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 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_DNL10SMD_07182012 10 FEATURE DESCRIPTIONS (CON.) The output voltage tracking feature (Figure 35 to Figure 37) 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 Sequential Start-up Sequential start-up (Figure 35) is implemented by placing an On/Off control circuit between VoPS1 and the On/Off pin of PS2. PS2 PS1 Vin Vin VoPS1 VoPS2 R3 On/Off R1 Q1 On/Off R2 C1 Simultaneous Simultaneous tracking (Figure 36) 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. Figure 35: Sequential start-up PS1 PS1 PS2 PS2 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 37) 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. The suggested value of R2 is 10kΩ. Vo, PS 2 Vo, PS1 = R2 R1 + R2 PS2 PS1 Vin Vin VoPS1 VoPS2 R1 TRACK 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’’). R2 On/Off On/Off Thermal Derating The high for positive logic The low for negative logic 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.
