MC33063ADG from onsemi, in a SOIC-8-150mil. 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 output switch transistor, rated 40 V maximum (VC(switch)) with switch current up to 1.5 A. |
| 2 | Switch Emitter | passive | Emitter of the internal output switch transistor, rated 40 V maximum (VE(switch)) with switch current up to 1.5 A. |
| 3 | Timing Capacitor | passive | Connection for the external timing capacitor CT that sets the oscillator frequency (33 kHz typ with CT = 1.0 nF). |
| 4 | GND | power_in | Ground. |
| 5 | Comparator Inverting Input | input | Inverting input of the comparator, compared with the 1.25 V reference threshold (input range -0.3 to +40 V) via the output-voltage divider. |
| 6 | VCC | power_in | Supply voltage input, operating from 3.0 V to 40 V. |
| 7 | Ipk Sense | input | Peak current sense input; the current limit trips at about 300 mV across the sense resistor Rsc between VCC and this pin. |
| 8 | Driver Collector | passive | Collector of the internal driver transistor, rated 40 V maximum with driver collector current up to 100 mA. |
