PWM controller from TI delivers 85% efficiency at full load

TI's new off-line green mode PWM controller UCC28610 delivers 85 percent at full load by using frequency and peak current modulation. TI claims, UCC28610 uses 30 percent fewer external components compared to standard flyback controllers. The UCC28610 is designed for applications with an output power range of 15W to 65W. Examples include AC/DC adapters, gaming, notebook and printer adaptors, LCD TVs and monitors, set top boxes, appliance power supplies, bias supplies or other supplies that need to meet ENERGY STAR efficiency standards or requirements under the Energy using Products (EuP) directive of the EU across the entire load range.

The key features of UCC28610 are:

125-mW no-load power consumption
Over current and overload protection
Cascoded MOSFET configuration enables better line surge raggedness than internal high-voltage FETs
