Dear RsBogdan,

Below is an excerpt from the older 'Re: About the issue of TWR-VF65GS10 power supply circuit' thread:

  1. If your customer does not use USB as a power source, all the below information is irrelevant.
  2. The issue was with a type of the previously used Switch IC controlling the USB power on the board - MIC2026, whose built-in current threshold appeared to be marginal for the latest SW applications, so it had to be replaced with a drop-in replacement, MIC2506, with a higher threshold.
  3. The next schematic revision (in progress) with MIC2506 instead of MIC2026 will be G1.

Best regards, Naoum Gitnik.
