Kit Overview

The TPS63020EVM-487TPS63020EVM-487 evaluation module is a fully assembled and tested circuit for evaluating the TPS63020TPS63020 Buck-Boost Converter with 4A Switch. The TPS63020EVM-487 operates from a 1.8V to 5.5V supply and provides a 3.3V output.The EVM is designed to help the user easily evaluate and test the operation and functionality of the TPS63020.

The TPS6302x devices provide a power supply solution for products powered by either a two-cell or three-cell alkaline, NiCd or NiMH battery, or a one-cell Li-Ion or Li-polymer battery. Output currents can go as high as 3A while using a single-cell Li-Ion or Li-Polymer Battery, and discharge it down to 2.5V or lower.

The buck-boost converter is based on a fixed frequency, pulse-width-modulation (PWM) controller using synchronous rectification to obtain maximum efficiency. At low load currents, the converter enters Power Save mode to maintain high efficiency over a wide load current range. The Power Save mode can be disabled, forcing the converter to operate at a fixed switching frequency.

The maximum average current in the switches is limited to a typical value of 4A. The output voltage is programmable using an external resistor divider, or is fixed internally on the chip. The converter can be disabled to minimize battery drain. During shutdown, the load is disconnected from the battery. The device is packaged in a 14-pin QFN PowerPAD package measuring 3 × 4 mm (DSJ).

Key Applications: All Two-Cell and Three-Cell Alkaline, NiCd or NiMH or Single-Cell Li Battery Powered Products, Ultra Mobile PC's and Mobile Internet Devices, Digital Media Players, DSC's and Camcorders, Cellular Phones and Smartphones, Personal Medical Products, Industrial Metering Equipment, High Power LED's.
