Fairchild Announces The FSGM0565R, FPS Power Switch for Off-Line Power Supplies Up to 60 Watts

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 30mW 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™) 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…
