UC1875-SP Datasheet (Texas Instruments) - Phase Shift Resonant Controller

UC1875-SP, Phase Shift Resonant Controller

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 efficiency performance at high frequencies.
