DESCRIPTION
PowerBoost 1000C is the perfect power supply for your portable project! With a built-in load-
sharing battery charger circuit, you'll be able to keep your power-hungry 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.
If you dont need the 1A battery charger, smart load-sharing, or 1A iOS resistors, check out the
Powerboost 500C
Like our popular 5V 1A USB wall adapter, we tweaked the output to be 5.2V instead of a
straight-up 5.0V so that there's a little bit of 'headroom' for long cables, high draw, the addition
of a diode on the output if you wish, etc. The 5.2V is safe for all 5V-powered electronics like
Arduino, Raspberry Pi, or Beagle Bone while preventing icky brown-outs during high current
draw because of USB cable resistance.
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. 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 (~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 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)
To make this even more useful, we stuck a smart load-sharing Lipoly 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 1000mA 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.
Since the built-in battery charger has load-sharing, it will automatically switch over to the USB
power when available, instead of continuously charging/draining the battery. This is more
efficient, and lets you charge-and-boost at the same time 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 1000mA max, and there's some inefficiency during the
boosting stage, so make super sure that the USB adapter you're using to charge with is high
quality, can supply 2A and has thick power wires. This one from Adafruit is ideal and has
been tested, lower quality ones will not act well due to the voltage drop on the wires or droop
on the power supply. This is especially true if you're actually drawing 1000mA out of the
PowerBoost 1000C, the MCP73871 maxes out at 1.8A.You do have to always have a LiPo
plugged into manage the load spikes, it's not optional!
This charger-booster is great for powering your robot, Arduino project, single-board-computer
such as Raspberry Pi or BeagleBone! 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, pick up a 3.5mm 2pin
block here and solder to the output spot where the USB jack would go. Or dont solder anything
in for a more compact power pack.

DOCTOR!
You may get an off-white or black JST connector.
