ENERGY HARVESTING TECHNOLOGY
Energy Harvesting is the process by which energy is derived from external sources (e.g solar power, thermal energy and piezo energy) capture and store for small, wireless autonomous devices used in wearable electronics and wireless sensor network (IOT devices).
Description
The LTC3330 integrates a high voltage energy harvesting power supply plus a DC/DC converter powered by a primary cell battery to create a single output supply for alternative energy applications. The primary cell input powers a buck-boost converter and energy harvesting powers a buck converter. The buck operates when harvested energy is available, reducing the quiescent current draw on the battery to essentially zero, thereby extending the life of the battery. The buck-boost powers VOUT only when harvested energy goes away. A low noise LDO post regulator and a super capacitor balancer are also integrated, accommodating a wide range of output storage configurations. Voltage and current settings for both inputs and outputs are programmable via pin-strapped logic inputs.
