for Automotive
1 Features 3 Description The UCC28730-Q1 isolated-flyback power supply
controller provides Constant-Voltage (CV) and
Constant-Current (CC) output regulation without the
use of an optical coupler. A minimum switching
frequency of 30 Hz facilitates achieving less than 5
mW of no-load power. This device processes
information from the primary power switch and an
auxiliary flyback winding for precise control of output
voltage and current. Qualified for Automotive Applications
