A monolithic GaN mains power converter IC was the target of Leibniz University Hannover, which worked with Texas Instruments. And the result is a 15W off-line PSU that can feed a 30-60V LED string with 140‑190mA from 60-400V AC or DC. Efficiency is 95.6% at low input voltage, and not dropping below 87.8% all the ...
