BD9F500QUZ
Nano Pulse Control™ 4.5 V to 36 V Input, 5 A Integrated MOSFET Single Synchronous Buck DC/DC Converter

BD9F500QUZ is a synchronous buck DC/DC converter with built-in low on-resistance power MOSFETs. It is capable of providing current up to 5A. It features fast transient response due to Constant On-Time control system. The Light Load Mode control improves efficiency in light-load conditions. It is ideal for reducing standby power consumption of equipment. Power Good function makes it possible for system to control sequence. It achieves the high power density and offer a small footprint on the PCB by employing small package.
