The combination of Solar energy, rechargeable batteries, and LED lighting can create light sources that provide the same amount of light as traditional incandescent bulbs but with lower power consumption, longer life, faster response and smaller size. This application note describes implementation of a high efficiency DC-DC step-up converter to deliver constant current to power a serial LED string from a single cell Li−Ion battery that's recharged from a solar cell.
