Product Overview

The TPS63002 is a Texas Instruments buck-boost DC-DC converter for Power_Management designs that need regulated conversion while the input voltage can be above or below the regulated output. The fixed TPS63002 output version provides 5.0 V, with VIN and VINA specified over a 1.8 to 5.5 V recommended operating range and a 1.9 to 5.5 V startup input range for the DC-DC stage.

Electrical characteristics include up to 96% efficiency, a 1600 mA minimum, 1800 mA typical, and 2000 mA maximum switch current limit at VIN = VINA = 3.6 V and TA = 25°C, and 100 mΩ typical high-side and low-side switch on-resistance. The internal oscillator is specified at 1250 kHz minimum and 1500 kHz typical, with external synchronization through PS/SYNC from 1250 to 1800 kHz.

The device is supplied in a 10-pin VSON (QFN/DRC), 3.00 mm x 3.00 mm package. Thermal data for this package includes 46.8°C/W junction-to-ambient resistance and 4.1°C/W junction-to-case bottom resistance. Protection and control functions include undervoltage lockout, overtemperature protection at 140°C typical, EN and PS/SYNC logic thresholds, shutdown current down to 0.1 µA typical, and load disconnect during shutdown.
