DESCRIPTION  
The UCC28710 family of flyback power supply  
controllers provides isolated-output Constant-Voltage  
(CV) and Constant-Current (CC) output regulation  
without the use of an optical coupler. The devices  
process information from the primary power switch  
and an auxiliary flyback winding for precise control of  
output voltage and current.

Programmable Cable Compensation  
(UCC28710, UCC28714 and UCC28715)  
An internal 700-V start-up switch, dynamically-  
controlled operating states and a tailored modulation  
profile support ultra-low standby power without  
sacrificing start-up time or output transient response.  
NTC Resistor Interface (UCC28711, UCC28712  
and UCC28713) with Fixed Cable  
Compensation Options  
Control algorithms in the UCC28710 family allow  
operating efficiencies to meet or exceed applicable  
standards. The output drive interfaces to a MOSFET  
power switch. Discontinuous conduction mode (DCM)  
with valley switching reduces switching losses.  
Modulation of switching frequency and primary  
current peak amplitude (FM and AM) keeps the  
conversion efficiency high across the entire load and  
line ranges.

SIMPLIFIED APPLICATION

–
VAC  
The controllers have a maximum switching frequency  
of 100 kHz and always maintain control of the peak-  
primary current in the transformer. Protection features  
help keep primary and secondary component  
stresses in check. The UCC28710, UCC28714 and  
UCC28715 allow the cable compensation to be  
programmed. The UCC28711, UCC28712 and  
UCC28713 devices allow remote temperature  
sensing using a negative temperature coefficient  
(NTC) resistor while providing fixed cable-  
compensation levels.
