DataSheet 30W, Dual Output EMC Considerations (Continued) This Common Choke L1 is defined as follows: ■ PMT-048 L:450μH±35% / DCR:25mΩ, max A height:9.8 mm, Max ■ All dimensions in millimeters Input Source Impedance The power module should be connected to a low impedance input source. Highly inductive source impedance can affect the stability of the power module. Input external L-C filter is recommended to minimize input reflected ripple current.
PAGE 21
DataSheet 30W, Dual Output Output Over Voltage Protection The output over-voltage protection consists of a Zener diode that monitors the voltage on the output terminals. If the voltage on the output terminals exceeds the over-voltage protection threshold, then the Zener diode clamps the output voltage. Short Circuit Protection Continuous, hiccup and auto-recovery mode. During a short circuit, the converter shut s down. The average current during this condition will be very low .

DataSheet 30W, Dual Output Heat Sink Consideration Use heat-sink (7G-0011C-F) for lowering temperature and higher reliability of the module.
PAGE 23
DataSheet 30W, Dual Output Remote ON/OFF Control The Remote ON/OFF Pin is used to turn on and off the DC/DC power module. The user must use a switch to control the logic voltage (high or low level ) of the pin referenced to -Vin. The switch can be an open collector transistor, FET and Opto-Coupler. The switch must be capable of sinking up to 0.5 mA at low-level logic voltage. High-level logic of the ON/OFF signal (maximum voltage): the allowable leakage current of the switch at 12V is 0.5mA.

DataSheet 30W, Dual Output Output Voltage Adjustment Output voltage set point adjustment allows the user to increase or decrease the output voltage set point of a module. This is accomplished by connecting an external resistor between the TRIM pin and either the Vo(+) or Vo(-) pins. With an external resistor between the TRIM and Vo(-) pin, the output voltage set point increases. With an external resistor between the TRIM and Vo(+) pin, the output voltage set point decreases.
