The need for a constant current source has been illustrated in this project which uses the TPS54232 step down swift DC/DC converter. The need for a constant current source has been illustrated in this ...

Having a big block of hot to dump current into is a very useful thing to have if you’re testing batteries, power supplies, high power LEDs, electroplating, or any thing else that would normally ...

Performance specs can be trumped, but elegance persists. Consider the most basic task in industrial control: driving sensors and bridges. It doesn’t matter if you’re dealing with a strain-gauge bridge ...
