SK6110CA33M5R

Suntek · DC-DC Converters · SOT-23-5

SK6110CA33M5R from Suntek, in a SOT-23-5. 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 EN input Shutdown pin: 'H' gives normal operation and 'L' stops step-up; datasheet limits are VSH min 0.75 V and VSL max 0.3 V, with input current within ±0.1 µA.
2 VOUT power_out Output voltage pin, rated VSS-0.3 V to VSS+8 V absolute maximum (page 4).
3 NC unconnected N.C. (not connected) pin, no function stated in the datasheet.
4 GND power_in GND pin, the circuit reference ground.
5 LX passive External inductor connection pin; absolute maximum LX voltage is VSS-0.3 V to VSS+8 V and LX current is 1000 mA (page 4).
