MC34063ADR-TP 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, the internal Darlington pair T1 collector; switch collector voltage is rated 40 V max and switch current 1.2 A max. |
| 2 | SE | passive | Switch emitter, the internal Darlington pair T1 emitter; switch emitter voltage is rated 40 V max. |
| 3 | CT | passive | Timing capacitor pin; the value of the selected capacitor sets the internal oscillator run rate (100 Hz to 100 kHz). |
| 4 | GND | power_in | Analog ground pin. |
| 5 | CII | input | Comparator inverting input that sets and initiates the Darlington pair output switch; threshold is 1.25 V typical. |
| 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; current limit sense voltage is 300 mV typical. |
| 8 | DC | passive | Driver collector (labelled Drive Collector in the block diagram); the pin table lists it as the internal Darlington pair T1 collector; driver collector voltage is rated 40 V max. |
