Power FPGAs
(1) Radiation tolerance is a typical value based upon initial device qualification with a dose rate = 10 mra.
The UC1875-SP implements control of a bridge power stage by phase-shifting the switching of one half-bridge with respect to the other, allowing constant frequency pulse-width modulation in combination with resonant, zero-voltage switching for high ef.
