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.
