Product Overview

The TPS63001 is a Texas Instruments single-inductor buck-boost converter for Power_Management applications requiring a regulated 3.3 V fixed output. It operates from VIN and VINA over a recommended 1.8 V to 5.5 V range, with the DC-DC stage specified for start-up from 1.9 V to 5.5 V. The device supports both step-down and boost operating regions, with 1200 mA output current specified for VOUT = 3.3 V and VIN = 3.6 V to 5.5 V, and up to 800 mA in boost mode when VOUT = 3.3 V and VIN is greater than 2.4 V.

Switching characteristics include a 1250 kHz minimum and 1500 kHz typical oscillator frequency, with external synchronization supported from 1250 kHz to 1800 kHz. The switch current limit is specified at 1600 mA minimum, 1800 mA typical, and 2000 mA maximum at VIN = VINA = 3.6 V and TA = 25°C. Both high-side and low-side switch on-resistance are 100 mOhm typical under VIN = VINA = 3.6 V.

The device is offered in a 10-pin VSON (QFN), DRC package, 3.00 mm x 3.00 mm. Operating ratings cover -40°C to 85°C free-air temperature and -40°C to 125°C virtual junction temperature, with thermal parameters specified for the DRC VSON package.
