Single-chip Type with Built-in FET Switching Regulators

Flexible Step-down Switching Regulator with Built-in Power MOSFET

●Description

Output 3.0A and below High Efficiency Rate Step-down Switching Regulator Power MOSFET Internal Type BD9876EFJ mainly used as secondary side Power supply, for example fromfixed Power supply of 12V, 24Vetc, Step-down Output of 1.2V/1.8V/3.3V/5V, etc, can be produced. This IC has external Coil/Capacitor down-sizing through 300kHz Frequency operation, inside Nch-FET SW for 45V “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.
