This application note is part of a series providing guidance for its readers to implement and validate a proven switch-mode power supply circuit for use in remote vital sign monitoring devices using Maxim Biosensing Analog Front Ends (AFEs).
The PMP9444 reference design provides all the power supply rails necessary to power Xilinx's Kintex UltraScale family of FPGAs. It features two UCD90120A's for flexible power up and power down sequencing as well as voltage monitoring, current monitoring, and voltage margining through the PMBus interface. This design uses a 12V input.
This reference design provides a power-supply circuit with an input voltage of 10.8V to 13.2V, an output voltage of 1.0V, and an output current of 5A using the MAX20751 and VT1697 chipset. The circuit was developed to power a MGTAVCC rail on a Xilinx® Kintex® Ultrascale™ FPGA, but it is also suitable for similar applications such as the MGTAVTT rail of Xilinx Virtex Ultrascale FPGAs.
