Synchronous buck DC-DC converter integrates low on-resistance power MOSFETs

Rohm's BD9B300MUV, a synchronous buck switching regulator with built-in low on-resistance power MOSFETs is now available from Mouser. Capable of providing current up to 3A, the device features fast transient response by employing constant on-time control system. It offers high oscillating frequency at low inductance. With its constant on-time control method which operates low consumption at light load, the device is ideal for equipment and devices that demand minimal standby power consumption. Applications include step-down power supplies for DSPs, FPGAs, microprocessors, etc., laptop PCs / tablet PCs / servers, LCD TVs, storage devices such as HDDs / SSDs, printers, OA equipment, entertainment products, distributed power systems and secondary power supplies.
