Linear Technology Dual Output DC/DC Converter Solutions for Xilinx FPGA Based Systems Handbook
The document addresses the power requirements of Xilinx FPGAs, which need multiple voltage rails including Vecint, Veco, and sometimes Vecaux. It highlights the importance of supply sequencing, tracking, and ramp time in these applications.
Three specific dual output DC/DC regulators are detailed: the LTC3407 for currents up to 600mA, the LTC3736 for 5A loads using 2-phase operation, and the LTC3708 for high-current applications exceeding 10A. The text provides application schematics, efficiency curves, and feature descriptions such as output tracking and programmable current limits.
