TPS62133RGTT

The TPS62133RGTT is a synchronous step down (buck) DC to DC converter with fixed output in 16 pin QFN package. This easy to use DC to DC converter is optimized for applications with high power density. A high switching frequency of typically 2.5MHz allows the use of small inductors and provides fast transient response as well as high output voltage accuracy by use of DCS-Control topology. The TPS62133 is suitable for systems powered from either Li-ion or other batteries as well as from 12V intermediate power rails. The output voltage start-up ramp is controlled by soft start pin which allows operation as either standalone power supply or in tracking configurations. Power sequencing is also possible by configuring enable and open drain power good pins. During power save mode, the device draw quiescent current of about 17µA from VIN and during shutdown mode, the device is turned off and shutdown current consumption is less than 2µA.
