Over Voltage Protection
The output overvoltage protection consists of circuitry that monitors the voltage on the output terminals. If
the voltage on the output terminals exceeds the over voltage protection threshold, the module will shutdown
into latch off mode. The overvoltage latch can be reset by either cycling the input power or toggling the
on/off signal for one second at least.
Note: Due to maximum duty cycle limt, output voltage can not be trimed up to OVP set point in low line
input.
Test setup:
R=10k ohm
