Datasheet
2.7V to 5.5V, 3A 1ch
Synchronous Buck Converter with
Integrated FET
BD8962MUV
General Description
The BD8962MUV is ROHM's 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 synchronous switches and
provides fast transient response to sudden load
changes by implementing current mode control.
Features
 Fast Transient Response because of Current Mode
Control System
 High Efficiency for all Load Ranges because of
Synchronous Switches
 Soft-Start Function
 Thermal Shutdown and UVLO Functions
 Short Circuit Protection with Time Delay Function
 Shutdown Function
Applications
