Employ LMP8646 and LMZ12003 for precision current limiting

Posted: 11 Jun 2012 ?? ?Print Version ?Bookmark and Share

Keywords:current limiter? linear regulator? resistive load?

The LMP8646 is a precision current limiter that may be employed to boost the current limit accuracy of any switching or linear regulator with an available feedback node. Many regulators might have an internal current limiter, but its output accuracy is often as high as 30%. The output accuracy of the LMP8646 can be as low as 3%, making it a preferred current limiter for many regulator applications. In this app note, we will discuss how to design the LMP8646 with the LMZ12003 voltage regulator and a resistive load application.
