DC-DC Buck Converter
Input Voltage: 60~140V (input voltage will be variable)
Input Current: 10A max (input current will be variable)
Output: 26~28.8v (Must be regulated by using PWM Frequency)
Output Current: 40A Max.
Design the Efficiency Curve and specially for 80V and 120v
Design the PCB Schematic
Design the PCB Layout
Export the design to GERBER and create a BOM
Let me know the operating frequency and min. max. duty cycles.
Converter must operate with very low loss.
