SD6303E30A

SHOUDING · DC-DC Converters · SOT-23

SD6303E30A from SHOUDING, in a SOT-23. 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 GND power_in Power ground (电源地) of the converter; the datasheet gives no voltage or current limit for this pin.
2 LX output Switching signal output (开关信号输出端); the datasheet limits LX to a maximum current of 1000 mA and gives a maximum voltage of 7 V for the VOUT and VLX pins.
3 VOUT input Input voltage pin (输入电压) as classified in the pin table; the absolute maximum voltage for the VOUT and VLX pins is 7 V.
