3 Description
This part is identical to UCC28063 with the exception
that the TSET pin Open/ Short Fault Detect and the
CS pin Open Fault Detect features are removed.
Removal of these Fault Detect features provides a
higher degree of noise immunity to provide increased
"ride-through" for applications where significant
voltage noise could be coupled onto the TSET or CS
pins during conditions of fast transient, surge or
impulse noise on the AC Supply.
Improved Efficiency and Design Flexibility Over
Traditional Single-Phase Continuous Conduction
Mode (CCM)
•
Inrush-Safe Current Limiting:
–
–
Prevents MOSFET Conduction During Inrush
Eliminates reverse Recovery Events in Output
