Single-chip built-in FET type Switching Regulator Series

Output 1.5A or Less High Efficiency

Step-down Switching Regulators

with Built-in Power MOSFET

BD9102FVM, BD9104FVM, BD9106FVM

No.09027EAT34

●Description

ROHM’s high efficiency step-down switching regulator (BD9102FVM, BD9104FVM, BD9106FVM) is a power supply

designed to produce a low voltage including 1.24 volts from 5 volts power supply line. Offers high efficiency with our

original pulse skip control technology and synchronous rectifier. Employs a current mode control system to provide faster

transient response to sudden change in load.

●Features

1) Offers fast transient response with current mode PWM control system.

2) Offers highly efficiency for all load range with synchronous rectifier (Nch/Pch FET)

and SLLM^TM(Simple Light Load Mode)

3) Incorporates soft-start function.

4) Incorporates thermal protection and ULVO functions.

5) Incorporates short-current protection circuit with time delay function.

6) Incorporates shutdown function

7) Employs small surface mount package MSOP8

●Use

Power supply for HDD, power supply for portable electronic devices like PDA, and power supply for LSI including CPU and

ASIC
