Hello, I'm working on a solar powered nixie watch (similar to the Kopriso Nixie watch).
It's crucial that I dramatically reduce stand-by power as much as possible and within 2.5uA, which is where the solar panels will balance off the stand-by current. Regardless of which power supply I use, even using the shutdown pin, the power supply still takes 2.5uA. This is perfectly in line with the electrical specifications of the datasheets. So, my question is, can I 'brute force' a shutdown, effectively removing the power from the VIN pin via a PNP high speed mosfet such as MMBTA42 or it will introduce too much of a delay in starting the power supply? I'm going to try it on the fly but if anyone has any suggestions on how to bring to 0 or to 0.01uA the stand-by current that would be great. As an example, I'm using the LT1308B DC/DC converter as on page 17 of the datasheet https://www.analog.com/media/en/technical-documentation/data-sheets/1308abfb.pdf Any suggestions will be much appreciated.
