SGM6603-3.3YN6G

SGMICRO · DC-DC Converters · SOT-23-6

SGM6603-3.3YN6G from SGMICRO, in a SOT-23-6. 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 SW passive Boost and rectifying switch input; the absolute maximum input voltage range on SW is -0.3V to 6V.
2 GND power_in Ground reference for the device.
3 EN input Enable input, active high (logic 1 at VCC enables, logic 0 at GND disables); EN high threshold is 2V minimum for 1.8V < VCC ≤ 3.3V and 2.6V for 4.2V < VCC ≤ 5.0V, and the EN input current is 1µA maximum.
4 NC unconnected No connect for the SGM6603-3.3 and SGM6603-5.0 fixed-output versions; it should be left floating.
5 VOUT power_out Boost converter output; the output voltage range is 2.5V to 5.5V and the absolute maximum rating on VOUT is -0.3V to 6V.
6 VCC power_in Boost converter supply voltage; the input voltage range after start-up is 0.9V to 5.5V.
