DC/DC Converter for SiC Driver
QA01C
Design Reference
1. Overload Protection
In normal operating conditions, the circuit of these products have no overload protection. Protect with a breaker is a simple way to
make overload protection.

5. It is not allowed to connect modules output in parallel to enlarge the power
6. The input and the output of the product are recommended to be connected to ceramic capacitor or
electrolytic capacitor. Using tantalum capacitor may cause risk of failure
