SY59515FAC

Silergy Corp · AC-DC Controllers And Regulators · SOP-8

SY59515FAC from Silergy Corp, 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 HV input HV start pin and HV OVP/UVP sense pin, with absolute maximum rating of -0.3V to 600V and HV OVP threshold of 455V to 511V at 0Ω RHV_EXT.
2 VCC power_in Bias supply for the low side circuit and LED OVP detection, rated -0.3V to 36V absolute maximum with VCC turn-on threshold of 10.6V to 12.2V.
3 LX input Low side driver control pin that receives the control signal from SY59516, with absolute maximum rating of -0.6V to 600V.
4 GND power_in Ground pin for the low side circuit and source of the low side internal 500V MOSFET.
5 HB passive Drain of the internal 500V MOSFET, with absolute maximum rating of -0.6V to 500V.
6 HB passive Drain of the internal 500V MOSFET, with absolute maximum rating of -0.6V to 500V.
7 HB passive Drain of the internal 500V MOSFET, with absolute maximum rating of -0.6V to 500V.
8 HB passive Drain of the internal 500V MOSFET, with absolute maximum rating of -0.6V to 500V.
