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
