Fairchild Semiconductor International introduces the FS8S0765RC Fairchild Power Switch (FPS), a highly integrated off-line power switch for CRT monitor fly-back power supply applications. This device integrates a fully avalanche-rated SenseFET (650V minimum breakdown rating) with a current mode PWM IC featuring primary side regulation. This unique combination minimizes external components, simplifies designs and lowers cost in target applications. Also featuring burst mode operation for stand-by mode (under 2W @ 265Vac), the new FS8S0765RC greatly lowers power consumption by reducing switching loss. Designs based on the FS8S0765RC enjoy performance that is superior to discrete MOSFET/controller or RCC switching converter solutions, while offering the benefits of reduced board space and improved reliability through various protection circuits. The FS8S0765RC's internal features include over-voltage, overload, over-current and thermal shutdown protection. To eliminate the screen noise generated by switching action, the FS8S0765RC turns on its internal MOSFET synchronously with the external sync signal. The Fairchild Power Switch offers an integrated fixed oscillator, under-voltage lockout, optimized blanking and a gate turn-on/turn-off driver, as well as temperature compensated precision current sources for loop compensation and fault protection circuitry. An internal, current sensing high-voltage SenseFET also provides a 650V minimum breakdown rating. The FS8S0765RC is available in a space-saving, TO-220-5L package. Price: FS8S0765RC U.S. $1.50 (1,000 pcs). Availability: Delivery: 8 weeks ARO. For more information, visit www.fairchildsemi.com, or contact your local Fairchild sales office.
