The PowerBoost 1000C 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.
Features
Sale!
Synchronous operation means you can disconnect the output completely by connecting the ENable pin to the ground. This will completely turn off the output
2A internal switch (~2.5A peak limiting) means you can get 1000mA+ from a 3.7V LiPoly/LiIon battery. Just make sure your battery can handle it!
Low battery indicator LED lights up red when the voltage dips below 3.2V, optimized for LiPo/LiIon battery usage
Onboard 1000mA charge-rate ‘iOS’ data resistors. Solder in the USB connector and you can plug in any iPad, iPhone or iPod for a 1000mA charge rate.
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 disabled (power and low batt LED are off)
