QUICK START GUIDE

The board layout accommodates most commonly used components.

1. Connect the positive and negative terminals of the load to VB and GND pins, respectively.

2. Preset Power Supply to 3.5V. Turn off Power Supply.

3. Connect Power Supply terminals to:

Positive (+): VIN

Negative (–): GND

4. Turn on Power Supply after making connections, MP5455 will charge the storage capacitor to

23.5V after DCDC converter completes start-up.

5. In order to observe the power release performance, following two methods can be applied:

Turn off the power supply.

Short VIN to GND directly. Note: make sure bench power supply have output current

limiting when doing this test.

6. Use R1 and R2 to set release voltage:
