The PI31xx series is a complete full-function, isolated DC/DC converter which requires only a few external components. Some of the programmable features that can be accessed by dedicated connections are a trim pin for output voltage trimming, a programmable soft-start, and remote On/Off enabled. There is also a temperature monitor function providing an analog output voltage proportional to the temperature of the highest internal module junction. The PI31xx is self-protected against fault conditions including input overvoltage, under-voltage lockout, over-temperature, and output overvoltage protection. A constant current limit threshold is employed to protect against short circuit and overload conditions. All fault conditions have an auto-restart function. The PI31xx converter also comes complete with all necessary safety and agency approvals.
