As a maker, we are always looking for the best way to power our projects. Usually, buck and boost converters are a considerable part of our project, because without good power, then everything else can be compromised. As important as it is, one does not want to splurge huge amounts of money on something that barely contributes to the end experience, but we also want the power supply to be reliable and sleep without wondering if everything can burn down easily, i.e. is protected. But enough mumbling about safety. Today, we bring you a cool boost converter that you may want to include into your next projects.
Over on Tindie, there is this interesting step up converter that can handle up to 600W of power. The interesting power rating is backed by adjustable voltage from 12 to 60 V and current from 0.2 to 10 A, starting with a 10 to 60 V input. Besides that, the input is protected through a fuse, so if you mess up too badly, there is the savior, ready to sacrifice itself for your circuitry. Looking at the outside, the connections are bare wires, which is justifiable due to the high currents, since not all connectors would handle that much current (and you probably do not intend to keep changing the connected cables), and the adjustments of both voltage and current are made through a trimmer potentiometer, that can surely handle with precision the large scales.
Regarding specifications, what is there for us to consider? Let us take a look:
- Input voltage from 10 to 60 V DC
- Continuously adjustable output voltage from 12 to 60 V
- Constant adjustable current range from 0.2 to 10 A
- Output current of up to 10 A (but needs a beefier heatsink for more than 6 A of current)
- Static operating current of 10 mA
- Maximum input current of 10 A, protected by a fuse
- Operating switching frequency of 150 kHz (no audible hissing)
- Conversion efficiency ranging from 92 to 96 %
- Operating temperature range from -40 to +85 ºC
- Dimensions of 85 x 52 x 21 mm and weight of 80 grams
