SLUS769D – JULY 2013 – REVISED DECEMBER 2016 UCC28910, UCC28911 High-Voltage Flyback Switcher
with Primary-Side Regulation and Output Current Control
1 Features 3 Description The UCC28910 and UCC28911 are high-voltage
flyback switchers that provide output voltage and
current regulation without the use of an optical
coupler. Both devices incorporate a 700-V power FET
and a controller that process operating information
from the flyback auxiliary winding and power FET to
provide a precise output voltage and current control.
The integrated high-voltage current source for startup
that is switched off during device operation, and the
controller current consumption is dynamically
adjusted with load. Both enable the very low stand-by
power consumption. 1 Constant-Voltage (CV) and Constant-Current (CC)
