MC34063ADR2G-JSM from JSMSEMI, 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 | output | Collector of the internal power switch transistor, rated up to 24 V (VC(switch) max) with switch current limited to 0.8 A absolute maximum (ISW). |
| 2 | SE | output | Emitter of the internal power switch transistor, rated up to 24 V (VE(switch) max), and tied to GND in the electrical test conditions. |
| 3 | CT | passive | Timing capacitor pin that sets the oscillator charge and discharge currents; the datasheet characterizes oscillator frequency with CT = 1.0 µF, giving 33 kHz typical (24 to 42 kHz). |
| 4 | GND | power_in | Ground reference pin for the device. |
| 5 | FB | input | Inverting input of the internal comparator, compared against the 1.25 V temperature-compensated reference (Vth 1.21 to 1.29 V), with input bias current up to 400 µA at 0 V. |
| 6 | VCC | power_in | Supply input, specified for 3.0 V to 24 V operation with an absolute maximum range of -0.3 V to 24 V. |
| 7 | Ipk | input | Current-limit sense input; the current-limit comparator sensitivity is 300 mV typical (250 to 350 mV) at matched charge and discharge currents. |
| 8 | DC | output | Collector of the internal driver transistor, rated up to 24 V with driver collector current limited to 100 mA maximum. |
