Datasheet
4.0V to 5.5V, 0.8A 1ch
Synchronous Buck Converter with
Integrated FET
BD8966FVM
General Description
The BD8966FVM is ROHM’s high efficiency
step-down switching regulator designed to produce a
voltage as low as 1V from a supply voltage of 5V. 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
PWM Control System
High Efficiency for All Load Ranges with
Synchronous Rectifier (Nch/Pch FET)
Soft-Start Function
Thermal Shutdown and UVLO Functions
Short-Circuit Current Protection with Time Delay
Function
Shutdown Function
Applications
Power Supply for LSI including DSP, Microcomputer
and ASIC
