Use of MagI³C power modules as flexibly adjustable constant current sources for a variety of applications

In the basic circuit, the MagI³C VDRM Power Modules deliver an adjustable, constant output voltage. However, applications such as LED lighting, SuperCaps and battery charging require a constant current source. With a simple additional circuit, the modules can be converted into such an adjustable constant current source with adjustable maximum voltage.

We will explain this conversion in detail on the basis of the reference design 178004 – MagI³C Current Source and invite you to learn more about it.
