• 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 pulse steering logic is configured to program either on-time for Timer ZCS systems (UC1865-1868), or off-time for ZVS applications (UC1861• Precision 1%, Soft-Started 5V 1864).
