L4992 TRIPLE OUTPUT POWER SUPPLY CONTROLLER

L4992 Description

® L4992 TRIPLE OUTPUT POWER SUPPLY CONTROLLER DUAL PWM BUCK CONTROLLERS (3.3V and 5.1V) 12V/120mA LINEAR REGULATOR DUAL SYNCH RECTIFIERS DRIVERS 96%.
The L4992 is a sophisticated dual PWM stepdown controller and power monitor intended for Notebook computer and/or battery powered equipment.

L4992 Applications

* The internal architecture allows to operate with minimum external components count. A very high switching frequency (200/300 KHz or externally synchronizable) optimizes their physical dimensions. Synchronous rectification and pulse skipping mode for the buck sections optimise the overall efficiency
