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) .
Merkmale
- MPPT (maximum power point tracking) provides optimal energy extraction from solar panels
- Internal battery charging and protection cicruits
- Input 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 application
- This design is a complete solution, including the solar current source, charge management solution, super cap and a built-in LDO regulator
