Datasheet
2.7V to 5.5V, 3.0A 1ch
Synchronous Buck Converter integrated FET
BD9132MUV
●General Description
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.
●Features
■ Offers fast transient response with current mode
PWM control system.
■ Offers highly efficiency for all load range with
synchronous rectifier (Nch/Nch FET) and SLLM
(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 Icc=0μA(Typ.)
