Solar Power Energy Harvester Reference Design Using a Super Cap
Texas Instruments
This reference design is a solar charger and energy harvester using a highly integrated power management solution that is well-suited for ultra-low power applications. The product is specifically designed to efficiently acquire and manage the microwatts (μW) to milliwatts (mW) needed to power your design. The storage method is a 47nF super capacitor that is charged and maintained by 4 series low power solar elements using MPPT (maximum power point tracking) .
Features
- MPPT (maximum power point tracking) provides optimal energy extraction from solar panelsInternal battery charging and protection cicruitsInput voltage regulation prevents collapsing high impedance input sources (boost)Programmable step-down regulated output (buck)Energy is stored in a super capacitor: for use in a low power applicationThis design is a complete solution: including the solar current source: charge management solution: super cap and a built-in LDO regulator
