Product Summary
The UC2875DWP is a Phase Shift Resonant Controller. It is an integrated circuit implement controlling 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. The UC2875DWP may be configured to providecontrol in either voltage or current mode operation, with a separateover-current shutdown for fast fault protection.
