Synchronous Buck Regulator with

Internal Power MOSFETs

Nov 29, 2012

Description

The RAA207700GBM is monolithic synchronous buck regulator with power MOSFETs in extremely small package.

The RAA207700GBM delivers high output current by small Rds(on) Power MOSFETs. Constant on time control

architecture provides fast transient response, and minimize external components. The RAA207700GBM operates skip

mode at light load, it provides high efficiency in all load condition. Three current ability products can be selected.

Features



Wide input voltage range: 3 V to 16 V

Constant-On-Time control

Built-in power MOSFETs suitable for PC, Server application

Very low stand-by current: 0.1 A (typ.)

Very low quiescent current :320 A (typ. at no load)

Switching frequency: Adjustable up to 2 MHz

High average output current, up to 15 A (7700GBM), 10 A (7701GBM), 5 A (7702GBM)

Controllable driver: Remote on/off
