UC33063AG

Slkor SLKORMICRO Elec · DC-DC Converters · SOP-8

UC33063AG from Slkor SLKORMICRO Elec, 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 Switch Collector input Collector of the internal Darlington pair (TI collector) used for the output switch.
2 Switch Emitter output Emitter of the internal Darlington pair (TI emitter) that drives the output switch.
3 Timing Capacitor passive The value of the selected timing capacitor sets the internal oscillator run rate.
4 GND power_in Ground reference pin; the datasheet gives no further description for this pin.
5 Comparator Inverting Input input Inverting input of the comparator, which can set and initiate the Darlington pair output switch.
6 VCC power_in Supply input; the datasheet states the device operates from 3.0V to 40V.
7 IPEAK Sense input Current sense input that monitors the voltage drop across an external resistor placed in series with VCC.
8 Driver Collector input Collector of the internal Darlington pair (TI collector) for the driver stage.
