Simple electronic load 2.0

Overview

The radiator is an old-fashioned AMD CPU radiator. It can be used naked if it is below 30W. It is recommended to use it in air cooling or soaking in water if it is above 30W.

The power supply is battery powered or draws power from the power source under test

I haven’t tested the reserved function of the fan interface. I mainly tested high-power water cooling.

The input is recommended to be below 30V and the current below 15A (if you want to strengthen it, you need to change the circuit. For example, I can measure 350W with IRFP250MOS tube)

Ask a question about the bootloader of TMS320C5517
I have a question about TMS320C5517 bootloader. The manual requires CLK_IN to be 11.2896, 12.0, 12.288, 16.8, or 19.2 MHz. If the 5517 has CLK_SEL = 1, CLK_IN = 26MHz, and Boot Modes selects 24-bit SP
