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
Power Good function
Over current protection/Over voltage protection/Thermal shutdown function
Built-in bootstrapping diode
Soft Start period adjustable
Enhanced light load mode function for higher efficiency
High drivability built-in line switch driver for low-loss line switch driving
Extremely small chip size package with solder bump
