Product Overview

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! This little DC/DC boost converter module can be powered by any 3.7V LiIon/LiPoly battery, and convert the battery output to 5.2V DC for running your 5V projects. 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!
  • Synchronous operation means you can disconnect the output completely by connecting the ENable pin to ground. This will completely turn off the output
  • 2A internal switch means you can get 500mA+ from a 3.7V LiPoly
  • Low battery indicator LED lights up red when the voltage dips below 3.2V, optimized for LiPo
  • Onboard 500mA charge-rate 'iOS' data resistors. Solder in the USB connector and you can plug in any iPhone or iPod for 500mA charge rate.
  • Full breakout for battery in, control pins and power out
  • 90%+ operating efficiency in most cases (see datasheet for efficiency graphs)
