Two-Stage Power Supply Reference Design for Field Transmitters
Description
This dual output reference design provides an example of how to power FPGAs: ASICs: or MCUs when space-constraints are a primary concern. The wide 6-V to 60-V input voltage range and the use of ultra-small and highly efficient DC/DC converters makes the design well suited for applications like industrial sensors: field transmitters: motor drives: and PLC modules. The two-stage approach provides a 1.5% accurate 5-V rail and a 1.5-V point of load rail with 1% accuracy across the entire temperature range. The output voltages are adjustable and can be adapted to the specific needs of the user.
