MC33063AQDRQ1 from Texas Instruments, in a SOIC-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 | output | Collector of internal NPN Darlington output switch transistor, absolute maximum voltage 40V, maximum peak current 1.5A with saturation voltage 1.3V at 1A in Darlington configuration. |
| 2 | Switch Emitter | passive | Emitter of internal NPN Darlington output switch transistor, absolute maximum voltage 40V, provides return path for switch current typically grounded. |
| 3 | Timing Capacitor | passive | External timing capacitor connection for oscillator frequency control; oscillator produces 24-42kHz typical frequency with 1nF capacitor value. |
| 4 | GND | power_in | Ground, 0V reference. |
| 5 | Comparator Inverting Input | input | Inverting input to precision 1.25V comparator, absolute maximum voltage rating -0.3V to 40V, receives output feedback for regulation control. |
| 6 | VCC | power_in | Power supply input, absolute maximum rating 40V, recommended operating range 3V to 40V, typical quiescent current 4mA with CT=1nF. |
| 7 | IPK | input | Peak current sense input from external sense resistor, current limit detection voltage 250-350mV typical 300mV; peak switch current determined by Ipk = 330mV/Rsense. |
| 8 | Driver Collector | output | Collector output of internal driver transistor, absolute maximum voltage 40V, maximum collector current 100mA, external transistor drive output for currents exceeding 1.5A. |
