NCP1345 controller equivalent, high-voltage quasi-resonant flyback controller.
a precise, primary side based output current limiting circuit to ensure a constant output current limit regardless of programmed output voltage, or nameplate output power.
Pin Name Pin Number
Function
Fault
1
The controller enters fault mode if the voltage on this pin is pulled above or below the fault thresholds. A
precise pull up current source allows direct interface with an NTC thermistor.
