App note: Precision current limiting with the LMP8646

in app notes by DP | 2 comments

Here is an app note from Texas Instruments describing how to use their LMP8646 ‘shunt’ current monitor as a current limiter on linear, and switching power supplies.

The LMP8646 is a precision current limiter used to improve 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.

    I’m always worried when I key a part number into octopart and get *zero* availability…

    You can get them from DigiKey but only in TSOT-6 and a minimum order of 1,000 with a lead time of 14 weeks.
