DataSheet 30W, Single Output EMC Considerations (Continued) Common Choke L1 is defined as follows: ■ L:450μH±35% / DCR:25mΩ, max A height: 9.8 mm, Max ■ All dimensions in millimeters Input Source Impedance The converter should be connected to a low impedance input source. Highly inductive source impedance can affect the stability of the converter. Input external L-C filter is recommended to minimize input reflected ripple current.
DataSheet 30W, Single Output Output Over Voltage Protection The output over-voltage protection consists of an output 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 Circuitry Protection Continuous, hiccup and auto-recovery mode. During a short circuit condition the converter will shut down. The average current during this condition will be very low.
DataSheet 30W, Single Output Heat Sink Consideration Use heat-sink (7G-0011C-F) f for lowering temperature and higher reliability of the module..
DataSheet 30W, Single Output Remote ON/OFF Control The Remote ON/OFF Pin is used to turn on and off the DC-DC converter. The user must use a switch to control the logic voltage (high or low level) of the ON/OFF pin, referenced to -Vi. The switch can be open collector transistor, FET or Opto-Coupler that is 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, Single 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.

DataSheet 30W, Single Output Safety and Installation Instruction Fusing Consideration Caution: This converter is not internally fused. An input line fuse must always be used. This encapsulated converter can be used in a wide variety of applications, ranging from simple stand-alone operation to an integrated part of sophisticated power architecture. For maximum flexibility, internal fusing is not included; however, to achieve maximum safety and system protection, always use an input line fuse.
