4.5V to 13.2V, 2A 1ch

Synchronous Buck Converter integrated FET

BD9141MUV

●General Description

●Key Specifications

ROHM’s high efficiency step-down switching regulator

BD9141MUV is a power supply designed to produce a

low voltage including 5.0/3.3 volts from 2 lithium cell

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.
