Texas Instruments Unveils Energy-Saving Chip for Consumer Electronics and AC Adapters
8-Pin Green-Mode Controller Enables Systems to Meet EPA Energy Star Standby Power Requirements(PresseBox) (Dallas, )
TI’s 8-pin, quasi-resonant, UCC28600 green-mode controller provides high power efficiency in full and light-load operating conditions and decreases power consumption in no-load standby mode. For example, the device enables standby power supplies in DLP(R) HDTVs, LCD and plasma digital TVs to achieve active-power mode efficiencies in excess of 88 percent and no-load power consumption levels below 300 milliwatts (mW). In addition, the UCC28600 improves power efficiency in notebook PC and gaming system AC adapters that support 40 watts (W) to 200 W. TI will demonstrate the energy-saving device in a 120-W adapter application at APEC from March 20-23 (TI booth #97 and #98).
14-Pin Performance in an 8-Pin Package
The UCC28600 is a flyback, pulse-width modulation (PWM) device that efficiently meets the U.S. Environmental Protection Agency’s Energy Star power requirements for consumer electronic systems. The controller implements quasi-resonant control techniques, frequency fold-back operation in light load conditions and features a dedicated pin to disable the power factor correction (PFC) stage in standby operation. The UCC28600 also integrates high-level protection features for energy-efficient power supplies up to 200 W, including cycle-by-cycle power limit and over-current hiccup re-start mode.
The UCC28600 comes in a simple-to-design, 8-pin SOIC package. It is sampling today from TI and its authorized distributors with volume production expected in the second quarter. Suggested resale pricing in quantities of 1,000 is $0.49. In addition, TI will conduct an hour-long seminar at APEC on “Designing by the Milliwatt – A Green-Mode Power Design Example” on Tuesday, March 21.
