Texas Instruments has made available power management controllers with standby power savings that will help smartphone users use less electricity with their 5-watt cube adapters, even when they are left plugged into the wall.
The UCC28700 primary-side controllers will result in smaller cubes, wireless power charging stations and other AC powered equipment.
Phone and adapter makers must meet new 5-Star low-power charging rating of <30mW, as set by the European Commissionís Integrated Product Policy (EC IPP), so consumers can select 5-W adapters that use the least energy. The highly efficient UCC28700 flyback controllers meet this requirement with the lowest standby power consumption, smallest solution size and component count, and greatest power density.

TI also introduced the TPS2511, an intelligent USB charging controller that complies with USB Battery Charging 1.2 specifications for charging adapters of popular smartphones or 5-V tablets.
TPS2511 intelligent USB charge controller meets the USB Battery Charging 1.2 specification, plus additional charge algorithms. It combines a current-limit USB power switch and a USB dedicated charging port identification circuit to automatically detect USB 2.0 and 3.0 data line voltages, and provide the correct electrical signature to safely charge compliant devices.
TI also introduced several new reference designs for download that include the TPS2511, UCC28700 and other TI power management circuits.
