BD9B333GWZ
Single Synchronous Buck DC/DC Converter, 2.7V to 5.5V Input, 3.0A Integrated MOSFET
BD9B333GWZ is a synchronous buck DC/DC converter with built-in low on-resistance power MOSFETs. This IC, which is capable of providing current up to 3A, features fast transient response by employing constant on-time control system. It offers high oscillating frequency at low inductance. With its original constant on-time control method which operates low consumption at light load, this product is ideal for equipment and devices that demand minimal standby power consumption. BD9B333GWZ achieves the high power density and offer a small footprint on the PCB by employing small CSP package.
