Texas Instruments TPS63020 Power Management IC

Extends Battery Life in Portable Devices

The Texas Instruments TPS63020 power management IC is the industry's smallest and highest performance buck-boost converter with a 4-A switch and up to 96 percent efficiency. The TI TPS63020 power management IC helps extend battery life in smartphones, portable medical equipment, DLP® pico projectors, and other battery powered multimedia devices. The TI TPS63020 buck-boost converter operates with a wide input voltage range of 1.8V to 5.5V and can discharge lithium batteries down to 2.5V or lower while maintaining excellent light load efficiency. The TI TPS63020EVM-487 evaluation module is a fully assembled and tested circuit for evaluating the TPS63020 buck-boost converter with 4A switch. The TPS63020EVM-487 operates from a 1.8V to 5.5V supply and provides a 3.3V output.
