Open Position for Step-Up Converter

For a current project I need a step-up converter to get 5 volts from 2.5V-5.5V input. The output of this converter is used to power sensors which drive motors and small heat elements from this source. The average consumed current is 160mA with a peek at 320mA.

In the photo you can see the latest Boldport project with a test setup for the XC9142B50DMR-G from Torex Semiconductor. I made the mistake and just relied on the specifications stated on the website from Mouser:

This looks really good: 500mA output current… So I did a quick test. Obviously the magic smoke in the photo is a composition, but this is what actually happened somewhere at a constant ~250mA load with 5V input. Continue reading Open Position for Step-Up Converter
