P14254: Underwater Thermoelectric Power Generation


Back to MSD 2

To test the TI TPS54426 regulation circuit, the chip was mounted on a breakout board and soldered onto a prototype board. Top:


A capture of the oscilloscope is shown below though the testing data is given in the testing section.

Though the prototype regulator circuit did not yield the desired results, the proper components were mounted on the main PCB and is shown below.

The following image is a zoomed view of the TPS54426 regulator soldered to the main board.
