PowerBoost 500 Basic - 5V USB Boost @ 1.8V+ 500mA
The DC/DC boost converter module can operate with 1.8V or higher batteries and can convert this voltage to 5.2V DC to power your 5V projects. 5V 1A USB duvar adaptörümüz gibi , We have adjusted the output to be 5.2V instead of a flat 5.0V, allowing for some "headroom" for long cables, high current draw, and the addition of a diode at the output. This makes it safe for all 5V electronic devices like Arduino, Raspberry Pi, or Beagle Bone, and prevents any "brown-outs" during high current draw due to USB cable resistance.
At the heart of the PowerBoost 500, there's a boost converter from TI called TPS61090. This boost converter chip, the TPS61090, comes with some really nice extras, including low battery detection, a built-in 2A switch, synchronous conversion, excellent efficiency, and high-frequency operation at 700KHz.
- Synchronous operation, meaning you can completely shut down the output by connecting the EN pin to ground. This will fully cut off the output.
- Built-in 2A switch (~2.5A peak limit), which means you can draw at least 500mA+ from as low as 1.8V, 750mA+ from 2 NiMH or Alkaline batteries, and at least 1000mA from a 3.7V LiPoly/LiIon battery or 3 NiMH/Alkalines.
- Low battery indicator LED: It lights up red when the voltage drops below 3.2V and is optimized for common use with LiPo/LiIon batteries.
- Built-in 500mA charge rate "Apple/iOS" data resistors: Solder them to the included USB connector, and you can charge any iPhone or iPod at a 500mA charge rate. Not recommended for iPad (which requires a 1A charge rate).
- Full output for battery input, control pins, and power output.
- Over 90% operational efficiency in most cases (refer to the datasheet for efficiency graphs) and low quiescent current: 5mA when enabled and the power LED is on, 20uA when disabled (power and low battery LED off).
Great for powering your robot, Arduino project, Raspberry Pi, or single-board computer like the BeagleBone! Each order comes with a fully assembled and tested PCB and a loose USB A jack. If you are powering your project from USB, solder on the USB A jack (a 3-minute soldering task). If you want to use a terminal block, you can get a 3.5mm 2-pin block from here and solder it to the output point where the USB jack would go. Or leave out anything for a more compact power pack.
