Abstract
A 5V-input, high-frequency, high-density (9A/mm 2 ) buck converter featuring a low-voltage GaN power transistor (with 5-10× better FoM than Si) with on-die gate clamps, integrated with a CMOS companion die in 4mm × 4mm package, achieves 94.2% peak efficiency for 5V in /1V out at 3MHz switching frequency with a 40nH inductor.
