MC34063S8

TECH PUBLIC · DC-DC Converters · SOP-8

MC34063S8 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: internal Darlington pair T1 collector.
2 SE passive Switch emitter: internal Darlington pair T1 emitter.
3 CT passive Timing capacitor pin; the selected capacitor value controls the internal oscillator run rate.
4 GND power_in Analog ground pin.
5 CII input Comparator inverting input that sets and initiates the Darlington pair output switch (input range -0.3 to +40 V).
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.
8 DC passive Drive collector: internal Darlington pair T1 collector (40 V maximum driver collector voltage).
