BD9B305QUZ
BD9B305QUZ is Single Synchronous Buck DC/DC Converter manufactured by ROHM.
2.7 V to 5.5 V Input, 3.0 A Integrated MOSFET Single Synchronous Buck DC/DC Converter
General Description
BD9B305QUZ is a synchronous buck DC/DC converter with built-in low on-resistance power MOSFETs. It is capable of providing current up to 3 A. 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.
