Datasheet

Single-chip Type with Built-in FET Switching Regulators

Flexible Step-down

Switching Regulators

with Built-in Power MOSFET

BD9876AEFJ

●General Description

●Key Specifications

Output 3.0A and below High Efficiency Rate Step-down

Switching Regulator Power MOSFET Internal Type

BD9876AEFJ mainly used as secondary side Power

supply, for example from fixed Power supply of 12V, 24V

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 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.
