  Hi Kazuto, We recommend using switching FETs with low Ciss as well. For example, the CSD17551Q3A FETs that are used on the EVM have a typical Ciss of 1050 pF. If the Ciss is large, then the switching FETs will have slower turn on/turn off times, which…

  Resolved

  Hi Kazuto, I have emailed you some more data regarding the REGN current capability. The REGN current limit has a typical value of 65 mA when the converter is enabled, which should be enough to support the customer's application with 30 nC FETs. However…

  We used to use wide trace for gate drive. You may try TI-FETs CSD17551Q3A since they have low gate capacitance.
