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. |
