DESCRIPTION  
Current Sense Discharge Transistor for  
Improved Noise Immunity  
The UCC28220 and UCC28221 are a family of BiCMOS  
interleaved dual channel PWM controllers. Peak  
current mode control is used to ensure current sharing  
between the two channels. A precise maximum duty  
cycle clamp can be set to any value between 60% and  
90% duty cycle per channel.  
Accurate Line Under and Over-Voltage Sense  
with Programmable Hysteresis  
Opto-Coupler Interface  
110-V Internal Start-Up JFET (UCC28221)  
Operates from 12-V Supply (UCC28220)  
Programmable Soft-Start  
UCC28220 has an UVLO turn-on threshold of 10 V for  
use in 12-V supplies while UCC28221 has a turn-on  
threshold of 13 V for systems needing wider UVLO  
hysteresis. Both have 8-V turn-off thresholds.
