| PowerBoost 1000 Basic - 5V USB Boost @ 1000mA from 1.8V+
PowerBoost is the perfect power supply for your power-hungry portable project! This little DC/DC boost converter module can run from 1.8V batteries or higher, and convert that voltage to 5.2V DC for running your 5V projects. With a beefy 4A DC/DC converter, it can give you 1A+ from as low as 2V.
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" 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 1000 has at the heart a TPS61030 boost converter from TI. 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 low as 1.8V, 1500mA+ from 2 NiMH or Alkaline batteries, and at least 2000mA from a 3.7V LiPoly/LiIon battery or 3 NiMH/Alkalines. Just make sure your batteries can actually supply the required 2-4A
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 out90%+ 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) 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, a loose 2-PH JST jack, a 2-pin Terminal block 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). Then choose either JST for input (JST is often used for our LiIon batteries, but the connector is only rated for 2A) or a terminal block.
The 1000 version comes with a 2-pin terminal block so you can solder it to the output spot where the USB jack would go. Or don"t solder any connectors in for a more compact power pack and go with 22AWG wires soldered directly in.
Dimensions: 29mm x 23mm x 2mm
Height w/ JST: 7.5mm
Hey there"s a typo on the back, it says TPS61090 but we really use the TPS61030 - the "90 is the 2A version, the "30 is the 4A version! We"ll fix on the next PCB run. Read more about the TPS61030 boost converter from TI here
