Design UCC28700-Q1
SLUSC61 – JANUARY 2015 UCC28700-Q1 Constant-Voltage, Constant-Current Controller
With Primary-Side Regulation
1 Features 3 Description The UCC28700-Q1 of flyback power supply
controllers provides 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. Low start-up current, dynamically
controlled operating states and a tailored modulation
profile support very low standby power without
sacrificing start-up time or output transient response. 1 Qualified for Automotive Applications
