Power Stage
Note: Due to the reverse battery protection a reverse protection diode for the light module may be obsolete. In case
of high ISO-pulse requirements and only minor protecting components like capacitors a reverse protection
diode may be reasonable. The external protection circuit needs to be verified in the application.
