New Integrated Power Switches Meet 1W Initiative

Green FPS™ Products Address 100 to 250 Watt Range

The 100W-rated FSCQ0765RT, 170W-rated FSCQ1265RT, and the 200W-rated FSCQ1565RT are specificially designed for quasi-resonant off-line Switch Mode Power Supplies (SMPS). The quasi-resonant converter lowers EMI, making these Green Fairchild Power Switch (FPS) devices well suited for applications that are sensitive to noise, and allows higher power conversion efficiency compared to conventional hard-switched converters with a fixed switching frequency.

The Green FPS products are highly integrated off-line power switches that incorporate a fully avalanche-rated SenseFET and current mode PWM IC in a single package to reduce system standby Power, EMI emissions, total component count and board space. These products feature burst mode operation for standby mode (under 0.1W @ 265Vac) to satisfy the international Energy Agency's (IEA) 1 Watt Initiative aimed at reducing standby power losses to below 1 Watt.

Features and Benefits

- Quasi-resonant converter for low EMI and high efficiency
- Advanced burst mode operation for low power consumption in standby mode
- Over current protection for high reliability in abnormal condition
- Built-in soft startup for preventing high current during startup from damaging the components in the SMPS

Applications

- Color TVs
- DVD receivers
- Audio devices
- Plasma display panels
