Product Overview
The TPS63020 is a Texas Instruments Power_Management IC described as a single-inductor buck-boost converter. It is intended for rails that can require buck or boost conversion across a recommended VIN and VINA range of 1.8 to 5.5 V, with the TPS63020 adjustable output voltage range specified from 1.2 to 5.5 V.
Electrical characteristics include 2200 to 2600 kHz oscillator and synchronization frequency range with 2400 kHz typical operation. At VIN = VINA = 3.6 V and TA = 25°C, the average switch current limit is 3500 mA minimum, 4000 mA typical, and 4500 mA maximum. High-side and low-side switch on-resistance are each 50 mΩ typical.
The device is offered in a DSJ VSON-14 package, 3 mm x 4 mm, with an exposed thermal pad. Thermal data for the package includes 41.8°C/W junction-to-ambient resistance and 3.6°C/W junction-to-case bottom resistance. System functions include EN, PS/SYNC, open-drain power-good output, undervoltage lockout, shutdown current down to 0.1 µA typical, and load disconnect during shutdown.
