Texas Instruments has introduced a small buck-boost converter with a 4 A switch and up to 96% efficiency, designed to extend battery life in battery-powered devices.
The TPS63020 operates with a wide input voltage range of 1,8 V to 5,5 V and can discharge lithium batteries down to 2,5 V or lower, while maintaining excellent light-load efficiency. The single-inductor, 2,4 MHz converter comes in a 3 x 4 x 1 mm package, and can achieve a complete DC/DC converter solution of 100 mm².
The device allows a battery-powered device to generate, for example, 3 A at 3,3 V in step-down mode and more than 2 A at 3,3 V in boost mode at typical conditions. A dynamic input current limit effectively protects the circuit and system, while a power saving mode maintains high efficiency at light load. The TPS63020 supports one-cell lithium-based or 2- or 3-cell alkaline, NiCd or NiMH batteries.
