Synchronous Buck Regulator with

Internal Power MOSFETs

Nov 29, 2012

Description

The RAA207703GBM is monolithic synchronous buck regulator with power MOSFETs in extremely small package.

The RAA207703GBM delivers high output current by small Rds(on) Power MOSFETs. Constant on time control

architecture provides fast transient response, and minimize external components. The RAA207703GBM operates skip

mode at light load, it provides high efficiency in all load condition. The RAA207703GBM incorporates internal 5V

LDO, so the regulator can operates single power supply. Three current ability products can be selected.
