Re: Oct 11 - Part IV: Current Hot Topic 1: Energy Harvesting Using Energy Harvesting to Power Wireless Sensors

NO RATINGS
For solar applications, there are some nice chips that automatically limit current to keep operation in the most efficient oprating zone for the PV cell (MPPT). But they seem to be very expensive, and not widely stocked. For example, the LTC3105 is $3.33 at 2500, but only 419 in stock at Digi-Key. Do you know of any good chips that are inexpensive and available enough for consumer products?

 Some info provided at teh following link but I do not know if the MPPT is part of their capability:
