● General 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

■ Offers fast transient response with current mode

PWM control system.

■ Offers highly efficiency for all load range with

synchronous rectifier (Nch/Pch FET)

and SLLMTM (Simple Light Load Mode)

■ Incorporates soft-start function.

■ Incorporates thermal protection and ULVO functions.

■ Incorporates short-current protection circuit with

time delay function.

■ Incorporates shutdown function

● Applications

Power supply for HDD, power supply for portable

electronic devices like PDA, and power supply for LSI

including CPU and ASIC
