MC34063ACD-TR from STMicroelectronics, 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 | SWC | output | Switch collector of internal Darlington output switch, rated for 1.5 A continuous current and 40 V maximum. |
| 2 | SWE | output | Switch emitter of internal output switch with saturation voltage 1.3 V (Darlington) or 0.7 V (forced high current). |
| 3 | TC | passive | Timing capacitor connection for oscillator frequency programming up to 100 kHz. |
| 4 | GND | power_in | Ground reference for all signal return paths. |
| 5 | CII | input | Comparator inverting input with 1.25 V threshold voltage and input range -0.3 to 40 V. |
| 6 | VCC | power_in | Power supply input with operating range 3-40 V and absolute maximum 50 V. |
| 7 | IPK | input | Current sense input for active current limiting with 300 mV sense threshold. |
