Product Description

DESCRIPTION
The UC1875 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 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.
FEATURES
•Zero to 100% Duty Cycle Control
•Programmable Output Turn-On Delay
•Compatible with Voltage or Current Mode Topologies
•Practical Operation at Switching Frequencies to 1MHz
•Four 2A Totem Pole Outputs
•10MHz Error Amplifier
•Undervoltage Lockout
•Low Startup Current –150µA
•Outputs Active Low During UVLO
•Soft-Start Control
•Latched Over-Current Comparator With Full Cycle Restart
•Trimmed Reference
