Adapter power controller offers lowest standby power

Texas Instruments has introduced a new power management controller with a 700V start-up switch that achieves less than 10mW of 'no-load' standby power in 5 and 10W cube adapters.

In addition to lower power capability, the new UCC28710 primary side, regulated flyback controller is said to help designers create smaller cube adapters and ac powered equipment. The device maintains a 78% average power efficiency at 5W, which TI says allows adapters to meet the European Commission's 5 Star no load power consumption rating of <30mW. The UCC28710 also leverages TI's new .25um, 700V analogue process technology, called LBC7HV, to integrate the start up switch - saving between 8 to 10mW of standby power.
