General Description

The UC3879 controls a bridge power stage by phase shifting the switching of one half-bridge with respect to the other.

This allows constant frequency pulse width modulation in combination with resonant, zero-voltage switching for high efficiency performance.

The UC3879 can be configured to provide control in either voltage mode or current mode operation, with overcurrent shutdown for fast fault protection.
