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. See more TI Precision Designs
