The power requirements As the power module start, a impulse current will formed, so please ensure that the power supply is sufficient to cope with the current. In general, the impulse current will be. times typical input current in consideration..

Pin pin is a terminal of the connective point of main filter capacitor in DC/DC converter (connect to capacitor cathode). Connecting a low ESR capacitor between the terminal and pin can improve the output ripple. 4. Pin pin provides an external control. The module is normal operation when this pin is not connected. If the pin is connected to high level the module will be close. Please refer to Recommended Circuit. Sink current on resistor R is no more than 0, value of R can be calculated from (sink-current: ~0): R VC-VD-0. 0 (kω) 4.
