UCC28730QDRQ1 Description
UCC28730QDRQ1 is a kind of zero-power standby PSR flyback controller that is designed to provide constant-voltage and constant-current output regulation requiring no optical coupler. The information from the primary power switch and an auxiliary flyback winding can be processed by UCC28730QDRQ1 for precise control of output voltage and current.
UCC28730QDRQ1 Features
Internal 700-V start-up switch
Dynamically controlled operating states
A tailored modulation profile
Low switching loss
High conversion efficiency
Available in the SOIC package
UCC28730QDRQ1 Applications
Automotive power supplies
Standby and auxiliary power supplies
Hybrid and electric vehicles in automotive
SMPS for home appliances and industrial automation
