SLUSC61A January 2015 – December 2020 UCC28700-Q1
PRODUCTION DATA
The UCC28700-Q1 is intended for AC/DC converters with input voltage range of 85 VAC(rms) to 265 VAC(rms) using Flyback topology. It can be used in other applications and converter topologies with different input voltages. Be sure 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.
