At this point I had to decide what to try and control. I wanted something that would be slow enough that the processor could keep up, but fast eno...en-USTelligent Community 12https://community.element14.com/members-area/personalblogs/b/blog/posts/pid-on-a-ek-tmc4c123gxl-evaluation-board-part-2-the-hardwareSun, 12 Mar 2017 19:58:19 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:42fb2d3c-0e9e-443e-a85c-5bcc5a796475DAB0<p>Nice post and good description of your circuit and test.</p><p>&nbsp;</p><p>DAB</p><img src="https://community.element14.com/aggbug?PostID=2666&AppID=293&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/members-area/personalblogs/b/blog/posts/pid-on-a-ek-tmc4c123gxl-evaluation-board-part-2-the-hardwareSun, 12 Mar 2017 09:46:16 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:42fb2d3c-0e9e-443e-a85c-5bcc5a796475michaelkellett1<p>The MOSFET waveform isn&#39;t that fast but it&#39;s nice and clean - so your converter might not be super efficient but it should be quite low noise.</p><p>&nbsp;</p><p>I wouldn&#39;t be that happy about the tantalum bead cap across the input&nbsp; - at least not for a production design because they are notorious for failing short and catching fire in power supply applications.</p><p>&nbsp;</p><p>The ripple current is quite low with no output capacitor - this kind of discrete component&nbsp; switcher is great for understanding how they actually work.</p><p>&nbsp;</p><p>Good luck with the PID.</p><p>&nbsp;</p><p>MK</p><img src="https://community.element14.com/aggbug?PostID=2666&AppID=293&AppType=Weblog&ContentType=0" width="1" height="1">
