DESCRIPTION  
The TPS51220 is a dual synchronous buck regulator controller with 2 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  
TPS51220 supports high efficiency, fast transient response and 99% duty cycle operation. It supports supply  
input voltage ranging from 4.5 V to 28 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. The D-CAP mode supports fast transient response. The high duty (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 TPS51220 can also synchronize to the external clock, and the interleaving  
ratio can be adjusted by its duty. The TPS51220 is available in the 32 pin 5x5 QFN package and is specified  
from –40°C to 85°C.
