With a compact design and the ability to operate from just 20mV, this device is perfect for powering wireless sensors and other innovative applications, making it an eco-friendly choice for tech-savvy professionals. ## Description OperationThe 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.This converter has three power outputs:1. A LDO voltage regulator with fixed 2.2V output2. Vout with selectable voltage and3. Vout2 which follows Vout in terms of voltage levelOutput voltage level is selected on the two solder jumpers, where the following combination is used:1+3 Vout = 5V1+4 Vout = 4.1V2+3 Vout = 3.3V2+4 Vout = 2.35VIn the above example, images, the selected Vout is 4.1 volts.There are also two control signals:1. PGood indicator signals the host micro-controller that the main output voltage is within regulation.2. Vout2_en is an input to the converter which is used to turn on the Vout2 output. ## Features - Based on LTC3108 with 1F and 0,1F storage caps and selectable output voltages - 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. - ou can light a LED with heat generated from your palm (with some setup). - LTC3108 board can extract electricity from heat. ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | ElectronicNuts | | Item model number | 4ChAcDimmer | | Item Weight | 0.81 ounces | | Product Dimensions | 2.36 x 2.09 x 0.79 inches | | Item Dimensions LxWxH | 2.36 x 2.09 x 0.79 inches | | Color | Multicolor | | Manufacturer | ElectronicNuts | | ASIN | B07495HDJH | | Is Discontinued By Manufacturer | No | | Date First Available | July 26, 2017 | ## Product Details - **Brand:** ElectronicNuts - **Color:** Multicolor - **Input Voltage:** 5 Volts - **Item dimensions L x W x H:** 2.36 x 2.09 x 0.79 inches - **Output Voltage:** 5 Volts ## Images ![Thermal Energy Harvesting power supply w/ LTC3108 and supercapacitor storage- Thermoelectric Collector - Image 1](https://m.media-amazon.com/images/I/81SgqJGbfUL.jpg) ![Thermal Energy Harvesting power supply w/ LTC3108 and supercapacitor storage- Thermoelectric Collector - Image 2](https://m.media-amazon.com/images/I/71jbmWCOnpL.jpg) ![Thermal Energy Harvesting power supply w/ LTC3108 and supercapacitor storage- Thermoelectric Collector - Image 3](https://m.media-amazon.com/images/I/81X9AypYN5L.jpg) ![Thermal Energy Harvesting power supply w/ LTC3108 and supercapacitor storage- Thermoelectric Collector - Image 4](https://m.media-amazon.com/images/I/71+Y+ZefC7L.jpg) ![Thermal Energy Harvesting power supply w/ LTC3108 and supercapacitor storage- Thermoelectric Collector - Image 5](https://m.media-amazon.com/images/I/71hM5mT4hCL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Solid build, works as expected! *by J***D on October 19, 2018* This product worked exactly as described. One thing to note, it takes a while for the super capacitors to charge, if you are using a very low power input (but after which point, forward voltage will occur, at expected output voltage). They have a website with FAQ, if you run into any issues. I am just an amateur/hobbyist, but it was easy to incorporate. Well built, and I will definitely be ordering more items from ElectronicNuts! ### ⭐⭐⭐⭐⭐ Works great *by L***A on December 30, 2018* Works as it should --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/46520674-thermal-energy-harvesting-power-supply-w-ltc3108-and-supercapacitor-storage](https://www.desertcart.hr/products/46520674-thermal-energy-harvesting-power-supply-w-ltc3108-and-supercapacitor-storage) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-10*
