BD9870FPS 数据手册

Single-chip Type with Built-in FET Switching Regulator Series

Simple Step-down

Switching Regulator

with Built-in Power MOSFET

BD9870FPS

No.09027EAT26

●Description

The BD9870FPS single-channel step-down switching regulator incorporates a Pch MOSFET capable of PWM operation at

900kHz, enabling use of a smaller coil, as well as circuitry that eliminates the need for external compensation – only a diode,

coil, and ceramic capacitor are required – reducing board size significantly.

●Features

1) Maximum switching current: 1.5A

2) 2. Built-in Pch FET ensures high efficiency

3) Output voltage adjustable via external resistors

4) High switching frequency: 900kHz (fixed)

5) Soft start time: 5ms (fixed)

6) Overcurrent and thermal shutdown protection circuits built in

7) ON/OFF control via STBY pin

8) Ceramic output capacitor compatibility

9) Small surface mount TO252S-5 package

●Applications

TVs, printers, DVD players, projectors, gaming devices, PCs, car audio/navigation systems, ETCs, communication

equipment, AV products, office equipment, industrial devices, and more.

●Absolute Maximum Ratings（Ta＝25℃）
