Resonant-Mode Power Supply Controllers  
FEATURES  
DESCRIPTION  
• Controls Zero Current Switched (ZCS) The UC1861-1868 family of ICs is optimized for the control of Zero Current  
or Zero Voltage Switched (ZVS)  
Quasi-Resonant Converters  
Switched and Zero Voltage Switched quasi-resonant converters. Differ-  
ences between members of this device family result from the various com-  
binations 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).  
• Zero-Crossing Terminated One-Shot  
Timer  
• Precision 1%, Soft-Started 5V  
Reference  
The primary control blocks implemented include an error amplifier to com-  
pensate the overall system loop and to drive a voltage controlled oscillator  
(VCO), featuring programmable minimum and maximum frequencies. Trig-  
gered by the VCO, the one-shot generates pulses of a programmed maxi-  
mum width, which can be modulated by the Zero Detection comparator.  
This circuit facilitates “true” zero current or voltage switching over various  
line, load, and temperature changes, and is also able to accommodate the  
resonant components' initial tolerances.  
• 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  
Under-Voltage Lockout is incorporated to facilitate safe starts upon  
power-up. The supply current during the under-voltage lockout period is  
typically less than 150µA, and the outputs are actively forced to the low
