FM2540TS

Shenzhen Fuman · AC-DC Controllers & Regulators · SOP-8

FM2540TS from Shenzhen Fuman, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VCC power_in Power supply pin, with a start threshold of 16.5V typical, UVLO of 9V typical, over-voltage protection of 31V typical, and an absolute maximum of -0.3 to 30V.
2 GND power_in Chip ground.
3 FB input Feedback voltage sampling pin from the auxiliary winding, with a 2V typical reference and an absolute maximum of -40 to 8.5V.
4 CS input Primary current sense pin, with a 500mV typical peak threshold and an absolute maximum of -0.3 to 7V.
5 D passive Drain of the internal 650V power MOSFET (3A drain current rating for FM2540TS).
6 D passive Drain of the internal 650V power MOSFET (3A drain current rating for FM2540TS).
7 D passive Drain of the internal 650V power MOSFET (3A drain current rating for FM2540TS).
8 D passive Drain of the internal 650V power MOSFET (3A drain current rating for FM2540TS).
