Introduction

AI Translation

TPS51220A-Q1 is a dual synchronous buck regulator controller with two LDOs, optimized for 5V/3.3V system controllers, enabling designers to cost-effectively complete the power supply for 2-cell to 4-cell notebook systems. The TPS51220A-Q1 supports high efficiency, fast transient response, and 99% operating duty cycle. It supports input voltages from 4.5V to 32V and output voltages from 1V to 12V. Two control schemes are available for selection based on the application. Peak current mode supports stable operation with lower ESR capacitors and output accuracy. D-CAP mode supports fast transient response. High duty cycle (99%) operation and wide input/output voltage range enable flexible design for compact mobile PCs and a variety of other applications. The fixed frequency is adjustable via resistor from 200kHz to 1MHz, with each channel operating at 180° phase shift. The TPS51220A-Q1 can synchronize to an external clock, with the interleaving ratio adjustable through its own duty cycle. The TPS51220A-Q1 is available in a 32-pin 5×5/4×4 QFN package, rated for ambient temperatures from -40°C to 105°C.
