Description

This Verified Design provides the theory, component selection, simulation, PCB design, and measurement details for a SPI controlled 36V power supply capable of sourcing 1A.  It also includes an intergrated high-side current shunt accurate to 1% across multiple decades of current load.  The output of the design is sourced by the DAC8871 which supports both unipolar and bipolar output ranges.  As a result, this circuit can be easily modified to meet the needs of many different applications.
