PWM drivers are used in analysing, testing, installing and powering all kinds of electronic and electrical devices. We have published a few designs in Elektor over the years: here we present a ‘de luxe’ version suitable for a very wide range of applications. As usual the software for the project (source code and hex file) can be downloaded for free from the accompanying pages on the Elektor website  and ready-programmed microcontrollers are also available.
