Integrated Load Switches versus Discrete MOSFETs
https://www.electronics-lab.com/integrated-load-switches-versus-discrete-mosfets/
Alek Kaknevicius @ ti.com discuss about load switches and the advantages of intergrated switches over discrete ones. The most common approach to load switching solutions is to use a Power MOSFET surrounded by discrete resistors and capacitors; however, in most cases using a fully integrated load switch has significant advantages. While both discrete and integrated […]

A 400W (1kW Peak) 100A Electronic Load Using Linear MOSFETs
https://www.electronics-lab.com/400w-1kw-peak-100a-electronic-load-using-linear-mosfets/
Kerry Wong built a 400W/100A electronic load using linear MOSFETs. He writes: I bought a couple of IXYS linear MOSFETs (IXTK90N25L2) a while ago to test their capabilities when used as electronic load, and the result was quite impressive. So I decided to build another electronic load using both MOSFETs. As you can see in the […]
