EVL6566B-65W-QR: 19V @ 3.42A, 90 ~ 264V in

Summary

This application note describes the characteristics and features of a 65 W demonstration board (EVL6566B-65W-QR), tailored to the specifications of a typical hi-end portable computer power supply.

The peculiarities of this design are the very high average efficiency of about 90%, without synchronous rectification, and very low no-load consumption of 100 mW at 230 Vac. The result is that this converter is more than compliant with Energy Star® eligibility criteria (EPA rev. 2.0 EPS).
