Synchronous Buck Converter integrated FET

BD9132MUV

●General Description

●Key Specifications

ROHM’s high efficiency step-down switching regulator

BD9132MUV is a power supply designed to produce a

low voltage including 0.8 volts from 5.5/3.3 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.
