PowerBoost 500C is the perfect power supply for your portable project!
With a built-in battery charger circuit, you'll be able to keep your project running even while recharging the battery!
The PowerBoost 500C has at the heart a TPS61090 boost converter from TI. This boost converter chip has some really nice extras such as low battery detection, 2A internal switch, synchronous conversion, excellent efficiency, and 700KHz high-frequency operation. Check out these specs!
To make this even more useful, Adafruit stuck a MicroLipo charger on the other side. The charger circuitry is powered from a microUSB jack, and will recharge any 3.7V/4.2V LiIon or LiPoly battery at 500mA max rate. There's two LEDs for monitoring the charge rate, a yellow one tells you its working, a green one lights up when its done. You can charge and boost at the same time no problem, without any interruption on the output so its fine for use as a "UPS" (un-interruptable power supply). Just be aware that the charge rate is 500mA max, so if you're drawing more than ~300mA continuously from the 5V output side, the battery will slowly drain since the charge rate is less than the dis-charge rate. You do have to always have a LiPo plugged into manage the load spikes, it's not optional!
Each order comes with one fully assembled and tested PCB and a loose USB A jack. If you are powering your project from USB, solder the USB A jack in (a 3-minute soldering task). If you would like to use a terminal block, you'll need to solder a 3.5mm 2pin block (not included) to the output spot where the USB jack would go. Or don't solder anything in for a more compact power pack.
You can also solder a switch in to create an output on/off switch!
Each order comes with a fully assembled and tested PowerBoost 500C + USB jack. Does not come with a Lipoly or LiIon battery, just pick one with more than 500mAh of capacity. Also doesn't come with the nice iPhone or charger cable. Be sure to read Adafruits lovely tutorial for details, schematics, and more!
