Reverse Input Voltage Protection
The input/output of this products is a non-isolated type and a step-down
DC-DC converter from (+) polarity to (+) polarity. If you connect the input
polarity reversed of this product by mistake it will be eventually damaged.
If there is a possibility of reverse connection, please add a protection
circuit as indicated in the following figure. The figure below is an example
using fuse and diode.

Over-Voltage Protection
This product does not have a built-in over-voltage protection.
When the switching element of this converter gets damaged by short
mode, input voltage (+Vin) will go out on the output.
For emergency if it gets damaged at over-voltage mode, please add
a circuit as below to intercept the supplying power circuit.
