    Power supply 1V for FPGA

    Hello, I need to get 1V from 5V, it is for an FPGA, Could someone recomend a circuit or IC?. Most of the DC DC converters that i found work from 1.5V and so on. I found this DC-DC_Step_UP-Down_ZK-SJVA-4X module , which can give from 0.5V output, but i could find the schematic. I hope can...
