TPS51222RTVT Description

TPS51222RTVT  is a type of dual synchronous buck regulator controller with two LDOs. It is specifically optimized for a 5-V/3.3-V system controller, enabling designers to cost-effectively complete a 2-cell to 4-cell notebook system power supply. Stability operation with a lower ESR capacitor and output accuracy can be supported in peak current mode. It ensures flexible design for small mobile PCs and a wide variety of other applications based on its 9% duty cycle operation and the wide input/output voltage range.
