QX2303L36F

QX Micro Devices · DC-DC Converters · SOT-23-5

QX2303L36F from QX Micro Devices, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 EN input Chip enable input, active-high. Drive high to enable normal boost operation; drive low to place the device in shutdown (minimum quiescent current). Voltage range −0.3 V to VOUT+0.3 V.
2 VOUT power_in Regulated boost output voltage sense/feedback pin (also the supply return path for the internal reference). Connected to the boost output node after the Schottky diode and output capacitor. Absolute maximum 7 V.
3 NC unconnected No connection. Leave floating.
4 GND power_in Power ground and analog return. Connect directly to the system ground plane with the input and output capacitor grounds.
5 LX output Switching node - drain of the internal boost NMOS. Connects to the boost inductor and to the anode of the external Schottky rectifier. Absolute maximum 7 V, peak switch current 1000 mA.
