Abstract
A novel high-voltage, ultra-high efficiency monolithic DC-DC Converter is presented. The disclosed architecture was integrated in the X-Fab XT018 SOI process using lateral Super Junction NMOS devices for up to 400V operation. Buck or boost voltage conversion is realized using high-voltage switched-capacitor and gate-driver techniques enabling efficiencies of > 98% peak efficiency, > 97% from 5% to 100% load. The topology is suitable for many applications including charging systems for cell-phones, tablets or other handheld devices, USB power conversion, AC-DC Adapters, DC-DC Point-of-Load (POL) and IoT applications. Block diagrams, simulated and measured results are presented showing the key features of this architecture, areas of interest and the performance summary.
