Looking for a low, LOW voltage boost converter in a tidy package? Dimension Engineering's LVBoost is just the solution!


Description [Hide]

What's the LVBoost do? Simply put, it takes a low voltage, and makes it higher and much more useful. There are many ways to do this, but the geniuses at Dimension Engineering have done a great job at doing this efficiently and in a tidy package. Of course, nothing comes for free, so what you are doing is converting extra current capacity into higher voltage. The LVBoost does this conversion while only losing ~15% of the energy - very nice! When it's just sitting there, it's only chewing up ~0.4mA - very little current.

What this means in a practical sense is that the LVBoost takes a voltage as low as 0.5V (like most large-ish solar cells put out), and can turn it into a useful voltage level adjustable between 2.2V to 5V, up to 1A output (assuming you have enough current in your source). It's also a tiny device, only weighing 3.5 grams.

These sorts of characteristics make the LVBoost ideal for boosting & regulating alternate power sources like small wind, solar, hand or hydro generators. Or plug it into one or two high-capacity alkaline cells to get a convenient 5V power source in a tiny package. This device will easily generate you some geek cred if you build it into something like a hamster-powered cellphone charger.

Here's the dirt on this neat device:

Specifications:

  • Input Voltage: 0.5V min - 5V max
  • Output Voltage: 2.5V min - 5V max
  • Continuous Input Current: 1A typ, 1.5A max
  • Continuous Output Current: 1.5A max
  • Output Ripple (Vpp): 20mV typ, 100mV max
  • quiescent Current Draw: 0.142mA min, 0.357mA typ, 1.310mA max
  • Efficiency: 85.6% typ, 92% max

L7805CV

5V Positive Voltage Regulator

The ST Micro L7805CV is a 1.5A, 5V positive linear regulator. It is the stronger older brother of the 78M05 but ironically it is the same size and shape, go figure. It may look like your everyday 7805 but looks can be deceiving!
