DESCRIPTION  
The UCC28610 brings a new level of performance  
and reliability to the AC/DC consumer power supply  
solution.  
Green-Mode (GM) Burst Switching Packets

Advanced Overcurrent Protection Limits RMS  
Input and Output Currents  
A
PWM modulation algorithm varies both the  
switching frequency and primary current while  
maintaining discontinuous or transition mode  
operation over the entire operating range. Combined  
with a cascoded architecture, these innovations result

Fast Latched Fault Recovery  
The UCC28610 offers a predictable maximum power  
threshold and a timed response to an overload,  
allowing safe handling of surge power requirements.  
Overload fault response is user-programmed for retry  
or latch-off mode. Additional protection features  
include output overvoltage detection, programmable  
maximum on-time, and thermal shutdown.
