L6563TR from STMicroelectronics, in a SOIC-14. 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 | INV | input | Inverting input of error amplifier that receives output voltage feedback and sinks tracking boost current. |
| 2 | COMP | output | Error amplifier output to which a compensation network must be connected for loop stability. |
| 3 | MULT | input | Rectified mains voltage input (0-3V range) to multiplier used for sinusoidal current reference and RMS voltage derivation. |
| 4 | CS | input | Current sense input with 1.7V threshold for abnormal current detection and inductor saturation protection. |
| 5 | VFF | input | Multiplier feedforward input requiring 1µF capacitor and parallel resistor to GND for 1/V² compensation peak-holding circuit. |
| 6 | TBO | output | Tracking boost output providing buffered VFF where current sunk through external resistor to GND adjusts output voltage. |
| 7 | PFC_OK | input | Output voltage monitor where >2.5V triggers latched shutdown and <0.2V triggers non-latched shutdown (restarts >0.26V). |
| 8 | PWM_LATCH | tri_state | Open-drain fault output that asserts high when PFC_OK >2.5V or CS >1.7V in L6563. |
| 9 | PWM_STOP | tri_state | Open-drain output that is pulled low when RUN <0.52V to temporarily stop DC-DC converter operation. |
| 10 | RUN | input | ON/OFF control input with 0.52V shutdown and 0.6V restart thresholds for brownout or discrete enable control. |
| 11 | ZCD | input | Zero current detector input for boost inductor demagnetization sensing where negative edge triggers MOSFET turn-on. |
| 12 | GND | power_in | Ground pin providing current return path for signal and gate driver circuit sections. |
| 13 | GD | output | Gate driver output with totem-pole stage providing 600mA source and 800mA sink current with ~12V high-level clamp. |
| 14 | VCC | power_in | Supply voltage input with 10.3-22V operating range after turn-on at 11-13V with 2.3-2.7V hysteresis. |
