Datasheet
2.7V to 5.5V, 3.0A 1ch
Synchronous Buck Converter with
Integrated FET
BD9132MUV
General Description
BD9132MUV is ROHMâs high efficiency step-down
switching regulator designed to produce a voltage as
low as 0.8V from a supply voltage of 5.5V/3.3V. It
offers high efficiency by using pulse skip control
technology and synchronous switches, and provides
fast transient response to sudden load changes by
implementing current mode control.
Features
ï® Fast Transient Response because of Current Mode
PWM Control System
ï® High Efficiency for All Load Ranges because of
Synchronous Switches (Nch/Nch FET) and SLLMTM
(Simple Light Load Mode)
ï® Soft-Start Function
ï® Thermal Shutdown and UVLO Functions
ï® Short-Circuit Protection with Time Delay Function
ï® Shutdown Function
