ZHCSEK1B December 2013 – October 2015 UCC28722
PRODUCTION DATA.
The UCC28722 is intended for AC/DC adapters and chargers with input voltage range of 85 VAC(rms) to 265 VAC(rms) using Flyback topology. This device can be used in other applications and converter topologies with different input voltages. Ensure that all voltages and currents are within the Recommended Operating Conditions and Absolute Maximum Ratings of the device. To maintain output current regulation over the entire input voltage range, design the converter to operate close to fMAX when in full-load conditions. To improve thermal performance, increase the copper area connected to GND pins.
