Connect the positive and negative terminals of the load to the VOUT and GND pins, respectively. 2. Preset the power supply output between 4.5V and 21V, and then turn off the power supply. 3. Connect the positive and negative terminals of the power supply output to the VIN and GND pins, respectively. 4. Turn the power supply on. The board will automatically start up. 5. To use the Enable function, apply a digital input to the EN pin. Drive EN higher than 1.4V to turn on the regulator, or less than 1.25V to turn it off. 6. Float AAM pin or drive AAM to a high level voltage to set MPM3610 work at force PWM mode. NOTICE: The information in this document is subject to change without notice.
