5-14V 3A 1ch Buck converter - BD9859EFJ

BD9859EFJ mainly used as secondary side Power supply, for example from fixed Power supply of 9V, 12V etc, Step-down Output of 1.2V/1.8V/3.3V/5V, etc, can be produced. This IC has external Coil/Capacitor down-sizing through 750kHz High Frequency operation, inside Nch-FET SW for 15V “withstand-pressure” commutation and also, High Speed Load Response through Current Mode Control is a simple external setting Phase compensation System, through a wide range external constant, a compact Power supply can be produced easily.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
