DESCRIPTION  
The TPS51221 is a dual synchronous buck regulator  
controller with 2 LDOs. It is optimized for 5V/3.3V  
system controller, enabling designers to cost  
effectively complete 2-cells to 4-cells notebook  
system power supply. The TPS51221 supports high  
efficiency, fast transient response and 99% duty cycle  
operation. It supports supply input voltages ranging  
from 4.5V to 28V, and output voltages from 1V to  
12V. Peak current mode supports stability operation  
with lower ESR capacitor and output accuracy. The  
high duty (99%) operation and 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  
1MHz by a resistor, and each channel runs 180° out  
of phase. The TPS51221 can also synchronize to the  
external clock, and the interleaving ratio can be  
adjusted by its duty. The TPS51221 is available in the  
32 pin 5×5 QFN package and is specified from –40°C  
to 85°C.
