According to our customer, the 820uF are quite large for a thermostat, e.g. 16mmx20mm . He have less than half that volume. Is there any repercussions if he replaced it with smaller electrolytic ones?
Also, his design draws current from a battery every cycle. He wants to run off of the HVAC power all the time and keep a battery charged. Is the reference design still suitable for that? He plan to keep my average current consumption less than 25mA from the HVAC.
In addition, he wants to know if there is a need for the load switches. Are they necessary?
Thanks to confirm!
