High power Buck convertor with mosfet switches

Project goal

The job called for a 120W buck convertor 48V to 24V which would supply power to 16 channels via I2C controlled switches.


The first step was to create a highly efficient DC-DC convertor to generate the 24V power. A synchronous buck configuration with external mosfets was chosen for this.

Once 24V was generated with all necessary circuit protection in place, a 100 pin ARM microcontroller (Cypress PSOC5) was used to take I2C commands and switch the corresponding channels on and off. Further current readings were taken from each channel for logging and monitoring purpose.
