DESCRIPTION:Switched-inductor power supplies are pervasive in electronics. 
 This is because they deliver a large fraction of the power they draw from 
 the input source with an output that is largely independent of the load. K
 eeping the output steady this way is ultimately the responsibility of the 
 feedback controller . This talk uses insight and intuition to show how hys
 teretic\, timed\, and clocked peak/valley loops control their outputs and 
 respond to sudden changes. The presentation also describes when sub-harmon
 ic oscillations surface and how slope compensation suppresses them. It the
 n shows how summing comparators work and how they can contract\, offset\, 
 and compensate these control loops and how comparators limit their input-t
 o-output translations in continuous conduction and output current in disco
 ntinuous conduction. With this background and understanding in hand\, desi
 gning compact feedback controllers for switched-inductor IoT power supplie
 s is not only possible but also more straightforward.\n\nCo-sponsored by:

X-ALT-DESC:Description: <br /><p class="p1">Switched-inductor power supplie
 s are pervasive in&nbsp\;electronics. This is because they deliver a large
 &nbsp\;fraction of the power they draw from the input&nbsp\;source with an
  output that is largely independent of&nbsp\;the load. Keeping the output 
 steady this way is <span class="s1">ultimately the responsibility of the f
 eedback </span>controller . This talk uses insight and intuition to show h
 ow hysteretic\, timed\, and clocked peak/valley loops control their output
 s and respond to sudden changes. The presentation also describes when sub-
 harmonic oscillations surface and how slope compensation suppresses them. 
 It then shows how summing comparators work and how they can contract\, off
 set\, and compensate these control loops and how comparators limit their&n
 bsp\;input-to-output translations in continuous&nbsp\;conduction and outpu
 t current in discontinuous <span class="s1">conduction. With this backgrou
 nd and </span>understanding in hand\, designing compact&nbsp\;feedback con
 trollers for switched-inductor IoT&nbsp\;power supplies is not only possib
 le but also more&nbsp\;straightforward.</p>\n<p class="p1">&nbsp\;</p>\n<p
