Description

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.
