More Information
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 complete 2-cell to 4-cell notebook system power supply. The TPS51222 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. Peak current mode supports stability operation with lower ESR capacitor and output accuracy. The high duty cycle (99%) operation and the wide input/output voltage range supports flexible design for small mobile PCs and a wide variety of other applications. The fixed frequency can be adjusted from 200 kHz to 1 MHz by a resistor, and each channel runs 180° out-of-phase. The TPS51222 can also synchronize to the external clock, and the interleaving ratio can be adjusted by its duty. The TPS51222 is available in the 32-pin 5 × 5 QFN package and is specified from -40°C to 85°C.
