Press Release Summary:
Model FSGM0565R FPS(TM) power switch features SenseFET 650 V startup circuit that includes drain-current sensing and shortens overcurrent time delay to less than 200 nsec. Suitable for off-line power supplies up to 60 W, switch achieves standby power consumption in 66 kHz flyback converter of 120 mW at 265 Vac in 25 mW of load. Product features multiple protection features, all with auto-restart, and offers supply-voltage range of 12-24 Vdc, 15 msec soft-start, and lightning surge immunity.
Original Press Release:
Fairchild Semiconductor's Power Switch Improves Off-Line Power Supply Designs
Integrated Solution Lowers Cost, Simplifies Design and Provides Complete Protection
SAN JOSE, Calif. - Responding to customer needs for solutions that can provide lower standby power consumption and easier design in off-line power supplies, Fairchild Semiconductor (NYSE: FCS) has developed the only power switch in the industry that integrates drain-current sensing in a 650 V internal avalanche-rugged SenseFET, reducing power dissipation and improving reliability by shortening the over-current time delay to less than 200 ns.
This FPS(TM) power switch for off-line power supplies up to 60 Watts (for universal AC input) - the FSGM0565R - achieves exceptional standby power consumption in a 66 kHz flyback converter: 120 mW at 265 Vac in with 25 mW of load. This is enabled by the SenseFET, a high-voltage startup circuit that turns off the startup resistor, and "soft burst" operation in standby, saving 30 mW and preventing the converter from generating audible noise.
Many protection features are built-in, all with auto-restart, to reduce component count in the power supply, providing designers with greater value and higher reliability. These include overload protection, over-voltage protection, abnormal over-current protection, internal thermal shutdown with hysteresis, output short protection and under-voltage lockout. The combination of low component count and high reliability makes this power switch attractive for many applications including LCD TVs and monitors-especially four-lamp LCD monitors.
Other advanced features include a wide supply-voltage range (12 to 24 Vdc), built-in 15 ms soft-start and enhanced lightning surge immunity.
The FSGM0565R, available in a 6-lead TO-220F package, is part of the Fairchild Power Switch (FPS(TM)) portfolio that offers design engineers many choices of integrated controllers and MOSFETs with complete circuit protection for power levels from a few Watts to a few hundred Watts.
