The current growth of always connected electronic devices keeps on pushing the demand for smaller power footprints and power efficiency to the limit.
Different input impedance measurement methods as well as their advantages and disadvantages are presented and compared based on real-life measurement results., 2016 in Eching near Munich (Germany).
Also this year we organized an Open-Lab, in the afternoon prior the Symposium, where participants could use our measurement equipment live and even bring their own designs to be tested.
Starting from first principles the operation and design of the voltage loop, the current loop and the voltage feed forward filter are detailed.
All design equations are presented along with a real life numerical design example.
Nevertheless in high current-slew-rate applications increased controller performance is required to provide tight regulation of the output voltage.
