Active clamp flyback chipset and buck battery charger cut power supply size and charge time

Texas Instruments has introduced several new power management chips that allow designers to boost efficiency and shrink power-supply and charger solution sizes for personal electronics and handheld industrial equipment. Operating at up to 1MHz, the new chipset combines the UCC28780 active clamp flyback controller and the UCC24612 synchronous rectifier controller to help cut the size of power supplies in AC/DC adapters and USB Power Delivery chargers in half. For battery-powered electronics that require maximum charging efficiency in a small solution size, the bq25910 6-A three-level buck battery charger allows up to a 60% smaller-solution footprint in smartphones, tablets and electronic point-of-sale devices. "Consumers want faster charging in a smaller footprint. These new solutions not only accomplish that but also enable designers to do more than they could before with less power," said Steve Lambouses, TI vice president, High Voltage Power.
