Additional Notes

GaN HEMT design

Precision output voltage droop mode control : Reliable current sharing in N+1 redundant applications

Wide Input Voltage Range accommodates input voltage transient conditions

 

Model 5032 is a modular, parallelable, radiation tolerant hermetic hybrid designed for bulk power conversion of 28V input bus voltage to nominal 28VDC regulated outputs. Each hybrid module provides 100 watts of output power and incorporates precision droop output voltage control to make paralleling multiple modules easy and straight forward without auxiliary interconnections or components. Up to five 5032 hybrids may be parallel connected to achieve very high load current; each module shares the total within 10% provided the interconnecting load bus construction is evenly apportioned to minimize I2R losses. Output voltage is precision trimmed at the factory to within 1/10th volt at half load to optimize current sharing, an adjust feature is provided to accommodate custom trims in application. GaN HEMT power conversion techniques make the model 5032 highly efficient and inherently radiation tolerant for gamma and single even effect environments.
