DESCRIPTION  
290-kHz, Adaptive On-Time D-CAP™ MODE  
Control  
The TPS51211 is a small-sized single buck controller  
with adaptive on-time D-CAP™ mode. The device is  
suitable for low output voltage, high current, PC  
system power rail and similar point-of-load (POL)  
power supply in digital consumer products. A small  
package with minimal pin-count saves space on the  
PCB, while a dedicated EN pin and pre-set frequency  
minimize design effort required for new designs. The  
skip-mode at light load condition, strong gate drivers  
and low-side FET RDS(on) current sensing supports  
low-loss and high efficiency, over a broad load range.  
The conversion input voltage which is the high-side  
FET drain voltage ranges from 3 V to 28 V and the  
output voltage ranges from 0.7 V to 2.6 V. The device  
requires an external 5-V supply. The TPS51211 is  
available in a 10-pin SON package specified from  
–40°C to 85°C.
