TPS51220RHBT Description

TPS51220RHBT is a type of dual synchronous buck regulator controller with two LDOs. It is specifically optimized for 5-V/3.3-V system controllers, enabling designers to cost-effectively complete 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 99% duty cycle operation and the wide input/output voltage range. 

TPS51220RHBT Features

Input voltage range: 4.5 V to 28 V

Output voltage range: 1 V to 12 V

Programmable droop compensation

Voltage servo adjustable soft start

180° phase shift between channels
