General Description

BD9F500QUZ is a synchronous buck DC/DC converter

with built-in low on-resistance power MOSFETs. It

capable of providing current up to 5 A. It features fast

transient response due to Constant On-Time control

system. The Light Load Mode control improves efficiency

light-load conditions. It is ideal for reducing standby power

consumption of equipment. Power Good function makes

possible for system to control sequence. It achieves the

high power density and offer a small footprint on the PCB

by employing small package.
