® PI31xx Series High Density Isolated DC-DC Converters Description Features The PI31xx is a family of high density, isolated DC-DC Zero-Voltage Switching (ZVS) converter modules integrating controller, power switches, planar magnetics, and support components all within a high density surface-mount package. This complete solution utilizes a high performance ZVS topology enabling high switching frequencies and providing best in class power density. The high switching frequency reduces input and output filtering requirements, further decreasing size and cost of the overall solution. nComplete isolated DC-DC These high density converter modules are offered in three input voltage operating ranges; 48 Vin nominal for communication applications, 28 Vin nominal for rugged high temperature or M-Grade applications, and 24 Vin nominal for industrial applications. All PI31xx converters offer a similar function and feature set. with Zero Voltage Switching Module n50 W / 60 W output power nEfficiency up to 89% (dependent upon converter model) nOutput voltage sensing without opto coupler use for higher reliability nThree input voltage ranges for Communication, Industrial, Rugged/M-Grade Applications nCommunication Converters have Max peak input voltage of 100V/100ms (non-operating) nSurface Mount 0.87” x 0.65” x 0.265” high density package Fully equipped with a variety of programmable features, the PI31xx includes output voltage trimming, programmable soft-start capability, and remote on / off ENABLE. There is also a temperature monitor function providing an analog output voltage proportional to the internal module temperature. The PI31xx is self-protected against fault conditions including: input over-voltage, under-voltage lockout, over-temperature, and output over-voltage protection. A constant current limit threshold is employed to protect against short circuit and overload conditions.
