QUICK START GUIDE
1. Connect the positive terminal of the load to VOUT pins, and the negative terminal of the load to
GND pins.
2. Preset power supply output to 4.75V to 23V and turn off the power supply.
3. Connect the positive terminal of the power supply output to VIN pin, and the negative terminal of
the power supply output to GND pin.
4. Turn power supply on and the MP2309 will automatically startup.
5. To use Enable function, apply a digital input to EN pin. Drive EN higher than 2.5V to turn on the
regulator, drive EN less than 0.7V to turn it off.
6. An under voltage lockout (UVLO) function can be implemented by the addition of a resistor
divider R4 and R5. The EN threshold is 2.5V, so VIN UVLO threshold is:

RECOMMENDED COMPONENTS FOR STANDARD OUTPUT VOLTAGES
The output voltage of this board is set to 3.3V. This board is laid out to accommodate most commonly
used inductors and output capacitors and to be programmed for most standard output voltages. The
following table lists recommended components for some standard output voltages. Listed
compensation components (R2, C3) values are based on the output capacitor installed on this board.
