TI delivers new 4-A switch buck-boost converter

BANGALORE, INDIA: Texas Instruments Incorporated (TI) today said that it has introduced the industry’s smallest and highest performance buck-boost converter with a 4-A switch and up to 96 per cent efficiency.

The TPS63020 power management integrated circuit (IC) helps extend battery life in smartphones, portable medical equipment, DLP pico projectors and other battery-powered multimedia devices, said a press release.

The buck-boost device 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, it added.

The single-inductor, 2.4-MHz TPS63020 converter comes in a 3-mm x 4-mm x 1-mm package, and can achieve a complete DC/DC converter solution of 100 mm2, more than 60 percent smaller than the competition.

“Designers of hand-held electronics continue to try to get more out of their batteries, especially now as they add wireless connectivity with higher data rates and more features to their handheld electronics,” said Steve Anderson, senior vice president of TI’s power management business unit.

“Higher current buck-boost converters, such as the TPS63020, help manage the power in the most efficient, most effective way possible, in the smallest amount of board space,” he added.
