  Hi Lukas, UVLO can also be connected to the output, e.g. with some external logic you can also stop discharge at a certain level if discharging -> pull UVLO high if standard supply is available. (mIght be just an additional Diode and Resistor) We have…

  Hi Stefan, The switching frequency was reduced and the output voltage increased from 10V to 16V. So I was able to increase the inductor to 3.3uF without any red space. We also used the same MOSFETs used in the EVM. More efficiency and less loss than ever…
