Description
- DESCRIPTION
- The TPS51220A 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 complete 2-cell to 4-cell notebook system power supply. The TPS51220A supports high efficiency, fast transient response, and 99% duty cycle operation. It supports supply input voltage ranging from 4.5 V to 32 V, and output voltages from 1 V to 12 V. Two types of control schemes can be chosen depending on the application. Peak current mode supports stability operation with lower ESR capacitor and output accuracy.
