UC1866 Overview
Controls Zero Current Switched (ZCS) The UC1861-1868 family of ICs is optimized for the control of Zero Curor Zero Voltage Switched (ZVS) rent Switched and Zero Voltage Switched quasi-resonant converters. DifQuasi-Resonant Converters ferences between members of this device family result from the various binations of UVLO thresholds and output options. Additionally, the Zero-Crossing Terminated One-Shot one-shot...
