DifQuasi-Resonant Converters ferences between members of this device family result from the various combinations 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).
Reference The primary control blocks implemented include an error amplifier to com• Programmable Restart Delay pensate the overall system loop and to drive a voltage controlled oscillator Following Fault (VCO), featuring programmable minimum and maximum frequencies.
