**Energy harvester for wireless remote sensor application.

Operates from Inputs of 20mV ( can change transformer to other energy sources. 1:20 ratio for peltier , 1:100 for small solar cell)

Complete Energy Harvesting Power Management System**

• Selectable V OUT of 2.35V, 3.3V, 4.1V or 5V
• LDO: 2.2V at 3mA
• Logic Controlled Output
• Reserve Energy Output
• Store energy on capacitor, supercapacitor, lithium cell or ceramic flexible cell.
• Can supply low power iot radio modules and sensors periodically.

DC/DC converter ideal for harvesting and managing surplus energy from extremely low input voltage sources such as TEGs (thermoelectric generators) and thermopiles. The step-up topology operates from input voltages as low as 20mV. It is a power source for wireless sensor applications where a Peltier element can be used on the input side. Operation

The DC/DC converter uses a small transformer to create an ultra-low input voltage step-up. It is ideally suited for low power wireless sensors and other applications in which surplus energy harvesting is used to generate system power because traditional battery power is inconvenient or impractical. The LTC3108 manages the charging and regulation of multiple outputs in a system in which the average power draw is very low, but there may be periodic pulses of higher load current required. This is typical of wireless sensor applications, where the quiescent power draw is extremely low most of the time, except for transmit bursts when circuitry is powered up to make measurements and transmit data. The converter can also be used to trickle charge a standard capacitor, super capacitor or rechargeable battery, using energy harvested from a Peltier element. A storage capacitor provides power when the input voltage source is unavailable. It can take an hour for all capacitors to receive their full charge.

This converter has three power outputs:

1. A LDO voltage regulator with fixed 2.2V output

2. Vout with selectable voltage and

3. Vout2 which follows Vout in terms of voltage level
