Texas Instruments  TPS53211RGTR

TPS53211 is a single phase PWM controller with integrated high-current drivers. It is used for 1.5 V up to 19 V conversion voltage.

TPS53211 features a skip mode solution that optimizes the efficiency at light load condition without compromising the output voltage ripple. The device provides pre-biased startup, soft-stop, integrated bootstrap switch, power good function, EN/Input UVLO protection. It supports conversion voltages up to 19 V, and output voltages adjustable from 0.8 V to 0.7×VIN.

The TPS53211 is available in the 3 mm × 3 mm, 16-pin, QFN package (Green RoHs compliant and Pb free) and is specified from –40°C to 85°C.
