High Voltage AC/DC Solutions

TI's highly reliable, efficient and low-cost high voltage AC/DC power solutions support a wide range of chargers and adapters. They are ideal for home appliance, smart meter, and industrial power supply applications. The 700V integrated power solutions deliver best-in-class efficiency and standby power that meet DOE (Level VI) and CoC (tier 1 and 2) regulations. TI's high-efficiency power management controller and switcher solutions reduce energy consumption and solution size.

UCC28910 and UCC28630 Flyback Power Solutions


The UCC28910 700-V flyback switcher with integrated high-voltage power MOSFET achieves the industry's best stand-by power consumption for 5- to 10-W designs. It features the lowest constant-current output tolerance of 5% providing an accurate, maximum current across different input voltages.
