SLUSDT2C August 2019 – December 2020 UCC28740-Q1
PRODUCTION DATA
The UCC28740-Q1 is well suited for use in isolated off-line systems requiring high efficiency and fault protection features such as USB compliant adapters and chargers for consumer electronics such a smart phones, tablet computers, and cameras. A 10-W application for a USB charger is shown in Figure 8-2.
This procedure outlines the steps to design a constant-voltage, constant-current flyback converter using the UCC28740-Q1 controller. See Figure 8-2 for component names and network locations. The design procedure equations use terms that are defined below.
