DESCRIPTION
The UC1861-1868 family of ICs is optimized for the control of Zero Current Switched and Zero Voltage Switched quasi-resonant converters. Differences between members of this device family result from the various combinations of UVLO thresholds and output options. Additionally, the one-shot pulse steering logic is configured to program either on-time for ZCS systems (UC1865-1868), or off-time for ZVS applications (UC1861-1864).

FEATURES
• Controls Zero Current Switched (ZCS) or Zero Voltage Switched (ZVS)
   Quasi-Resonant Converters
• Zero-Crossing Terminated One-Shot Timer
• Precision 1%, Soft-Started 5V Reference
• Programmable Restart Delay Following Fault
• Voltage-Controlled Oscillator (VCO) with Programmable Minimum and Maximum Frequencies
   from 10kHz to 1MHz
• Low Start-Up Current (150µA typical)
• Dual 1 Amp Peak FET Drivers
• UVLO Option for Off-Line or DC/DC Applications
