LTC3108 Li-Ion Battery Charger and 2.2V LDO Powered by a Solar Cell with Indoor Lighting

Li-Ion Battery Charger and 2.2V LDO Powered by a Solar Cell with Indoor Lighting

The LTC3108 is a highly integrated DC/DC converter ideal for harvesting and managing surplus energy from extremely low input voltage sources such as TEGs (thermoelectric generators), thermopiles and small solar cells. The step-up topology operates from input voltages as low as 20mV.
