MC34063S8 from TECH PUBLIC, 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 | SC | passive | Switch collector: internal Darlington pair T1 collector. |
| 2 | SE | passive | Switch emitter: internal Darlington pair T1 emitter. |
| 3 | CT | passive | Timing capacitor pin; the selected capacitor value controls the internal oscillator run rate. |
| 4 | GND | power_in | Analog ground pin. |
| 5 | CII | input | Comparator inverting input that sets and initiates the Darlington pair output switch (input range -0.3 to +40 V). |
| 6 | VCC | power_in | Power supply input, operation from 3.0 V to 40 V (40 V absolute maximum). |
| 7 | Ipk | input | Peak current sense input that monitors the voltage drop across an external resistor placed in series with VCC. |
| 8 | DC | passive | Drive collector: internal Darlington pair T1 collector (40 V maximum driver collector voltage). |
