Due to increase consumption of non-renewable energy for example, petroleum and the urgency of improving the ecological environment, energy harvesting, and solar energy, has become a hot topic in the world. More products choose solar as the power resource. The typical system powered by solar cell includes solar panel, energy storage element, similar to supercap or NiMH battery and the DC/DC device for charging the energy storage element from the solar panel, and others DC/DC to regulate output voltage. The result is specifically designed to the system powered by solar energy (less than 5 W). The Buck CC/CV feature ensures that the energy storage similar to super-cap or NiMH battery can be charged well. This result can nearly realize MPPT (Maximum Power Point Tracking) by using bi-directional buck or boost feature in TPS61094. And TPS61094 integrates a 60-nA ultra-low Iq boost converter to regulate output voltage no matter that the solar energy is strong or weak.
