Synchronous Buck Converter
Integrated FET
BD91501MUV
●Description
ROHM’s buck converter BD91501MUV is a 2ch output
power supply designed to produce a low voltage
including 2.55V/0.4A and 1.8V/0.3A from 3.3V 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 (Pch/Nch FET) and SLLMTM
(Simple Light Load Mode)
Incorporates soft start function
Incorporates thermal protection and UVLO function
Incorporates short-current protection with timer
latch
Incorporates shutdown function Icc=0µA (Typ.)
Full 100% Duty function
2ch output power supply (2.55V, 1.8V)
