A blisteringly fast 400V monolithic gallium nitride power buck converter featured at the International Solid-State Circuit Conference this week. Its figures speak for themselves: 50MHz operation, sub-200ps dead-time, and 120V/ns slew rate at the switching node. The child of National Chiao Tung University and Realtek Semiconductor, both in Taiwan, the IC is all GaN-on-silicon, combining a ...
