MC34063AL-D08-T from UTC(Unisonic Tech), in a DIP-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 | Switch Collector | passive | Collector of the internal Darlington output switch pair; maximum switch collector voltage is 40 V. |
| 2 | Switch Emitter | passive | Emitter of the internal Darlington output switch pair; maximum switch emitter voltage is 40 V. |
| 3 | Timing Capacitor | passive | The value of the selected timing capacitor controls the internal oscillator run rate. |
| 4 | GND | power_in | Ground pin of the device. |
| 5 | Comparator Inverting Input | input | Inverting input of the comparator that sets and initiates the Darlington output switch, with a 1.25 V threshold (1.21 to 1.29 V) and an input range of -0.3 to +40 V. |
| 6 | VCC | power_in | Supply voltage pin, operating from 3.0 V to 40 V with an absolute maximum of 40 V. |
| 7 | IPEAK Sense | input | Current sense input monitoring the voltage drop across an external resistor placed in series with VCC. |
| 8 | Driver Collector | passive | Collector of the internal Darlington driver transistor; maximum driver collector voltage is 40 V. |
