Datasheet

The PowerBoost 1000 has at the heart a TPS61030 boost converter from

TI (http://adafru.it/dLY). This boost converter chip has some really nice extras such as low

battery detection, 4A 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

4A internal switch means you can get 1000mA+ from as lo w as 1.8V,

1500mA+ from 2 NiMH or Alkaline batteries, and at least 2000mA fro m a 3.7V

LiPoly/LiIon battery or 3 NiMH/Alkalines. Just make sure your batteries can actually

supply 3-4A, OK?

Low battery indicator LED lights up red when the voltage dips below 3.2V,

optimized for the most common usage of LiPo/LiIon battery usage

On-board 1000mA charge-rate 'Apple/iOS' data resistors. Solder in the included USB

connector and you can plug in any iPhone or iPod for a speedy 1000mA charge rate.

Works with iPads, both mini and 'classic' type.

Full breakout for battery in, control pins and power out

90%+ operating efficiency in most cases (see datasheet for efficiency graphs),

and low quiescent current: 5mA when enabled and power LED is on, 20uA when
