Linear Technology IC solutions for renewable energy applications
Each of the products listed in Table 1 has specific features and performance criteria, which make it viable as the optimum solution depending on the type of ambient energy source.
In general terms, these include:
. Low standby quiescent currents – typically less than 6µA and as low as 450nA
. Low start-up voltages – as low as 20mV
. High input voltage capability – up to 34V continuous and 40V transients
. Ability to handle AC inputs
. Multiple output capability and autonomous system power management
. Auto-polarity operation
. Maximum Power Point Control (MPPC) for solar inputs
. The ability to harvest energy from as little as 1°C temperature delta
. Compact solution footprints with minimal external components
