Product Description

Operation
The DC/DC converter makes use of a small transformer to create an extremely low enter voltage step-up. It’s ideally suited to low energy wi-fi sensors and different purposes wherein surplus vitality harvesting is used to generate system energy as a result of conventional battery energy is inconvenient or impractical. The LTC3108 manages the charging and regulation of a number of outputs in a system wherein the common energy draw may be very low, however there could also be periodic pulses of upper load present required. That is typical of wi-fi sensor purposes, the place the quiescent energy draw is extraordinarily low more often than not, aside from transmit bursts when circuitry is powered as much as make measurements and transmit information. The converter can be used to trickle cost a regular capacitor, tremendous capacitor or rechargeable battery, utilizing vitality harvested from a Peltier component. A storage capacitor supplies energy when the enter voltage supply is unavailable.
This converter has three energy outputs:
1. A LDO voltage regulator with fastened 2.2V output
2. Vout with selectable voltage and
3. Vout2 which follows Vout when it comes to voltage degree

Output voltage degree is chosen on the 2 solder jumpers, the place the next mixture is used:
1+Three Vout = 5V
1+Four Vout = 4.1V
2+Three Vout = 3.3V
2+Four Vout = 2.35V

Within the above instance, photographs, the chosen Vout is 4.1 volts.

There are additionally two management indicators:

1. PGood indicator indicators the host micro-controller that the principle output voltage is inside regulation.

2. Vout2_en is an enter to the converter which is used to activate the Vout2 output.

Product Options

  • Primarily based on LTC3108 with 1F and 0,1F storage caps and selectable output voltages
  • DC/DC converter best for harvesting and managing surplus vitality from extraordinarily low enter voltage sources similar to TEGs (thermoelectric mills) and thermopiles.
  • The step-up topology operates from enter voltages as little as 20mV. It’s a energy supply for wi-fi sensor purposes the place a Peltier component can be utilized on the enter aspect.
  • ou can mild a LED with warmth generated out of your palm (with some setup).
  • LTC3108 board can extract electrical energy from warmth.
