BD8963EFJ
General Description
The BD8963EFJ is ROHM's high efficiency step-down
switching regulator designed to produce a voltage as
low as 1.0V 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.
