Product Description

The UC2875NG4 is a Phase Shift Resonant Controller 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. This family of circuits may be configured to provide control in either voltage or current-mode operation, with a separate over-current shutdown for fast fault protection. A programmable time delay is provided to insert a dead-time at the turn-on of each output stage. This delay, providing time to allow the resonant switching action, is independently controllable for each output pair. With the oscillator capable of operation at frequencies in excess of 2MHz, overall switching frequencies to 1MHz are practical.
Programmable output turn-on delay
Compatible with voltage or current mode topologies
Four 2A Totem pole outputs
10MHz Error amplifier
Undervoltage lockout
Outputs active low during UVLO
Soft-start control latched over-current comparator with full cycle restart
Trimmed reference
