FAN6300HMY

onsemi · AC-DC Controllers And Regulators · SOIC-8

FAN6300HMY from onsemi, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 DET input Detection input tied through a divider to an auxiliary transformer winding. Generates the zero-current-detect (ZCD) valley-switching signal, provides a line-compensation offset for constant power limiting, and forms the output OVP comparator against an internal 2.5 V reference (latched shutdown).
2 FB input Feedback input from the secondary-side error amplifier / optocoupler collector. Input impedance ~5 kΩ equivalent with a 1/3 attenuator to the PWM comparator. If FB voltage exceeds ~4.2 V for more than 55 ms, open-loop protection latches off.
3 CS input Current-sense comparator input. Connect to a sense resistor at the source of the external power MOSFET; the resulting voltage drives cycle-by-cycle peak-current limiting and leading-edge blanking is applied internally.
4 GND power_in Power ground and signal ground. A 0.1 µF decoupling capacitor is recommended between VDD and GND close to the IC.
5 GATE output Totem-pole PWM gate-drive output for the external power MOSFET. Output voltage is clamped internally to 18 V to protect the MOSFET gate-source oxide.
6 VDD power_in Controller supply pin. Two-step UVLO with turn-on threshold ~16 V and turn-off ~10 V. Startup current below 20 µA and operating current below 4.5 mA.
7 NC unconnected No internal connection. Leave floating or tie to a copper island for isolation between HV and VDD.
8 HV power_in High-voltage startup input. Connects to the rectified bulk DC line to supply the internal HV startup current source that charges the VDD capacitor. Disabled once VDD exceeds the turn-on threshold to minimize standby power.
