SD6800BC from Hangzhou Silan Microelectronics, 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 | COMP | bidirectional | RC loop compensation pin and output of the transconductance amplifier, which sets the constant on-time control (Tonmax is specified with COMP connected to 4V via 20K). |
| 2 | FB | input | Feedback voltage input that senses the auxiliary winding voltage through a resistor divider; the MOSFET turns on when FB falls to 0.2V, and FB over-voltage triggers at 1.46V typical (1.38V to 1.54V). |
| 3 | CS | input | Current sense input from the sense resistor; the cycle-by-cycle current limit turns off the MOSFET when the threshold reaches 0.6V typical (0.49V to 0.71V). |
| 4 | GND | power_in | Ground reference for the controller. |
| 5 | DR | output | Gate drive output for the external MOSFET, clamped to 17.5V typical (16V to 19V) at the high level, with 0.7A minimum peak sink current and 0.2A minimum peak source current at 1nF load. |
| 6 | VCC | power_in | Supply pin with operating range 9V to 18V after start-up, turn-on threshold 16V typical, turn-off at 8.0V typical, and over-voltage protection at 23V typical; internal clamp is 27V at 20mA. |
| 7 | NC | unconnected | No connection, listed as NC in the pin description. |
| 8 | NC | unconnected | No connection, listed as NC in the pin description. |
