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
Power Supply for LSI including DSP, Microcomputer
and ASIC
