Description

The UC2875DWPTRG4 family of integrated circuits 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 combi-nation with resonant, zero-voltage switching for high efficiency performance at high frequencies. This family of circuits may be configured to provide control in either voltage or current mode operation, with a se parate over-current shutdown for fast fault protection. UC2875DWPTRG4 Features • Zero to 100% Duty Cycle Control• Programmable Output Turn-On Delay• Compatible with Voltage or CurrentMode Topologies• Practical Operation at SwitchingFrequencies to 1MHz• Four 2A Totem Pole Outputs• 10MHz Error Amplifier• Undervoltage Lockout• Low Startup Current –150µA• Outputs Active Low During UVLO• Soft-Start Control
