Figure1. Interface Description

NOTE:

1. The input voltage must within 15V.
2. Load current should not be in 600mA or above for a long time, otherwise it will affect the service life of the module and even burn out.
3. If the load current is relatively high, you should increase the minimum input voltage to ensure normal operation.
