/PRNewswire/ -- Texas Instruments Incorporated (TI) (NASDAQ:TXN) today introduced a power management controller with a 700-V start-up switch that achieves less than 10 mW of "no-load" standby power in 5- and 10-watt cube adapters used with smartphones and tablets. In addition to the lower power capability, the new UCC28710 primary-side, regulated flyback controller helps designers create smaller cube adapters and AC-powered equipment.

The innovative controller maintains an industry-best 78-percent average power efficiency at 5 watts, which allows adapters to meet the European Commission's 5-Star no-load power consumption rating of <30 mW. The UCC28710 also leverages TI's new .25um, 700-V analog process technology, called
, to integrate the start-up switch -- saving an additional 8 mW to 10 mW of standby power.
Key features and benefits of the UCC28710:
Speed time-to-market with adapter charging reference designs
- Lowest standby power: achieves <10-mW standby power consumption and provides high-voltage start-up capability.
- Highest integration with primary-side regulation: eliminates the need for an optocoupler and TL431 feedback circuit; supports widest input voltage range with VDD, resulting in smaller bias capacitors; supports smaller transformers because of its high-frequency operation; and reduces overall design size and complexity without the need for additional external circuits.
family of UCC287xx controllers
includes the UCC28700, UCC28701 and other products to help customers simplify and speed their adapter designs. A new UCC28710 controller-based
10-W AC Eco-charger for tablets and smartphones
design adds to TI's growing
PowerLab™ reference design library
for AC adapters, universal USB charging cubes and car chargers.
Availability and pricing
The UCC28710 flyback controller is available in a 7-pin, SOIC package and is priced at
in quantities of 1,000. The 5-W
evaluation module is available for ordering through TI's eStore. The module converts a 90-V to 265-V RMS input voltage down to 5 V DC, with a 1-A current limit for USB adapter applications.
