TPS51222 Overview
The TPS51222 is a dual synchronous buck regulator controller with two LDOs. It is optimized for 5-V/3.3-V system controller, enabling designers to cost effectively plete 2-cell to 4-cell notebook system power supply. The TPS51222 supports high efficiency, fast transient response, and 99% duty cycle operation.
