Datasheet
4.5V to 18V, 3A 1ch
Synchronous Buck Converter
BD95835EFJ
●Description
BD95835EFJ is a 1ch synchronous buck converter that
can generate a wide range of output voltage at the input
voltage range (4.5V to 18V). Space-saving and high
efficient switching regulator can be achieved due to
built-in N-MOSFET power transistors. The IC also
incorporates constant ON TIME control mode which
facilitates ultra-high transient response against changes
in load. Variable soft start function, short circuit
protection and over voltage protection are incorporated.
The BD95835EFJ is designed for power supplies for
Digital AV Equipment.
