A highly inductive source 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 Safety Considerations Remote On/Off 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. The DCS 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 DCS series power modules. 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 10A fuse in the ungrounded lead. Input Under voltage Lockout At input voltages below the input under voltage lockout limit, the module operation is disabled. The module will begin to operate at an input voltage above the under voltage lockout turn-on threshold. For negative 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). Negative logic On/Off signal turns the module ON during the logic high and turns the module OFF during the logic low. When the negative On/Off function is not used, tie the pin to GND (module will be On). For positive logic module, the On/Off pin is pulled high with an external pull-up 5kΩ resistor (see figure 33). Positive logic On/Off signal turns the module OFF during logic high and turns the module ON during logic low. If the Positive On/Off function is not used, tie the pin to Vin.

When an analog voltage is applied to the SEQ pin, the output voltage tracks this voltage until the output reaches The amount of power delivered by the module is the the set-point voltage. The final value of the SEQ voltage voltage at the output terminals multiplied by the output must be set higher than the set-point voltage of the current. When using the trim feature, the output voltage of module. The output voltage follows the voltage on the the module can be increased, which at the same output SEQ pin on a one-to-one basis. By connecting multiple current would increase the power output of the module. modules together, multiple modules can track their output Care should be taken to ensure that the maximum output voltages to the voltage applied on the SEQ pin. power of the module must not exceed the maximum rated For proper voltage sequencing, first, input voltage is power (Vo.set x Io.max ≤ P max). applied to the module. The On/Off pin of the module is left unconnected (or tied to GND for negative logic Voltage Margining modules or tied to VIN for positive logic modules) so that the module is ON by default. After applying input voltage Output voltage margining can be implemented in the DCS 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, R margin-down, from the Trim pin to the output pin for margining-down. Figure 3 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 to the module, a minimum 10msec delay is required before applying voltage on the SEQ pin. This delay gives the module enough time to complete its internal power-up soft-start cycle. During the delay time, the SEQ pin should be held close to ground (nominally 50mV ± 20 mV). This is required to keep the internal op-amp out of saturation thus preventing output overshoot during the start of the sequencing ramp. By selecting resistor R1 (see Figure. 38) according to the following equation 24950 R1 Vin 0.05 Rmargin-down Q1 On/Off Trim Rmargin-up Rtrim The voltage at the sequencing pin will be 50mV when the sequencing signal is at zero. Q2 GND Figure 37: Circuit configuration for output voltage margining Output Voltage Sequencing The DCS 12V 6A modules include a sequencing feature, EZ-SEQUENCE that enables users to implement various types of output voltage sequencing in their applications. This is accomplished via an additional sequencing pin. When not using the sequencing feature, either tie the SEQ pin to VIN or leave it unconnected.

Monotonic Start-up and Shutdown After the 10msec delay, an analog voltage is applied to The DCS 6A modules have monotonic start-up and the SEQ pin and the output voltage of the module will shutdown behavior for any combination of rated input track this voltage on a one-to-one volt bases until the voltage, output current and operating temperature range. output reaches the set-point voltage. To initiate simultaneous shutdown of the modules, the SEQ pin voltage is lowered in a controlled manner. The output voltage of the modules tracks the voltages below their set-point voltages on a one-to-one basis. A valid input voltage must be maintained until the tracking and output voltages reach ground potential. When using the EZ-SEQUENCETM feature to control start-up of the module, pre-bias immunity during startup is disabled. The pre-bias immunity feature of the module relies on the module being in the diode-mode during start-up. When using the EZ-SEQUENCETM feature, modules goes through an internal set-up time of 10msec, and will be in synchronous rectification mode when the voltage at the SEQ pin is applied. This will result in the module sinking current if a pre-bias voltage is present at the output of the module. Figure 38: Circuit showing connection of the sequencing signal to the SEQ pin. Simultaneous tracking (Figure 41) is implemented by using the TRACK pin. The objective is to minimize the DS_DCS04S0A0S06NFA_03192012 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.
