FL7701MX from onsemi, in a SOIC-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 | CS | input | Current sense pin that limits the output current via the sense-resistor voltage and is also used to set LED current regulation; maximum allowed sense voltage is 5 V. |
| 2 | OUT | output | Gate drive output connected to the MOSFET gate, with peak source/sink drive current of 250 mA maximum. |
| 3 | VCC | power_in | Supply pin for stable IC operation, also used for ZCD signal detection for accurate PFC function; absolute maximum 20 V. |
| 4 | RT | input | Sets the operating frequency through an external resistor; with the pin open or floating the IC runs at a preset fixed frequency, maximum 5 V. |
| 5 | ADIM | input | Analog dimming pin tied to an internal current source so an external resistor can change the output current; if unused, connect a 0.1 µF bypass capacitor between ADIM and GND; maximum 5 V. |
| 6 | GND | power_in | Ground of the integrated circuit. |
| 7 | NC | unconnected | No connection. |
| 8 | HV | input | High-voltage pin connected to the high-voltage line to supply current to the IC; absolute maximum 500 V. |
