Description
General part information
TPS51211 Series
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.
