26.7 A 100A 93.4%-Peak-Efficiency LLC Resonant Converter with an Embedded Primary-Current-Extracted Regulator
Abstract
This paper presents a$100 \mathrm{A} 93.4 \%$-peak-efficiency LLC resonant converter with an embedded primary-current-extracted regulator. The proposed regulator powers the gate drivers of the LLC converter, eliminating the need for an external auxiliary buck converter or additional auxiliary windings. Fabricated in a$0.18 \mu \mathrm{m}$BCD process, the proposed regulator occupies a die are of$8.3 \text{mm}^{2}$and achieves a 60 V-to-2 V conversion at 1 MHz with a peak efficiency of 93.4%.
