Description
The Adafruit PowerBoost 1000C is the ultimate power supply module for portable electronics and DIY projects. Featuring a built-in load-sharing battery charger circuit, it lets you keep your power-hungry projects running continuously even while recharging the battery. Powered by any 3.7V Li-ion or LiPo battery, this high-efficiency DC/DC boost converter steps the output up to 5.2V DC to safely run 5V electronics like Arduino, Raspberry Pi, or BeagleBone.
The output is cleverly tweaked to 5.2V instead of a straight 5.0V to provide essential “headroom” for long cables, high current draw, or voltage drops, preventing annoying brown-outs. At its heart is TI’s TPS61090 boost converter chip, offering a 2A internal switch, synchronous operation, low battery detection, and high-frequency operation. The onboard smart load-sharing LiPo charger runs off a Micro-USB jack, recharging your battery at a 1000mA max rate while automatically switching power sources so you can use the module as an uninterruptible power supply (UPS).
Note: Product images are for reference only; actual appearance or component packaging may vary slightly based on manufacturing batches. (Note: This board is designed to be used with a LiPoly battery ; it will not operate without one.)
Key Features
- Smart Load-Sharing UPS Functionality: Automatically switches between USB power and battery power, allowing you to charge and boost simultaneously without output interruption.
- Optimized 5.2V DC Output: Provides safe 5.2V power to eliminate brown-outs caused by USB cable resistance and high current draw.
- High-Current Power Delivery: 2A internal switch (~2.5A peak limiting) delivers 1000mA+ output current from a compatible 3.7V LiPo/LiIon battery.
- Synchronous Enable Control: Completely disconnects the output by pulling the ENable pin to ground, dropping quiescent current down to just 20uA.
- Dual Charge Status LEDs: Includes independent yellow (charging) and green (fully charged) indicators, plus a red low-battery warning LED that lights up when voltage dips below 3.2V.
- Onboard iOS Data Resistors: Built-in 1000mA charge-rate resistors allow you to plug in an iPad, iPhone, or iPod for rapid charging.
Benefits
- Continuous Uninterruptible Power: Perfect for portable field gear, robotics, and remote data loggers that require reliable backup power.
- High Operating Efficiency: Achieves 90%+ operating efficiency in most cases with low quiescent current draw.
- Ultra-Compact Footprint: Measures just 19 × 32 mm and weighs a mere 2.5 grams, making it effortless to integrate into tight enclosures.
Applications
- Portable Electronics & Robotics: Ideal power supply module for mobile robots, handheld instruments, and field electronics.
- DIY Single-Board Computers: Reliable 5V power source for Raspberry Pi Zero, Arduino boards, and custom microcontroller builds.
- Custom Power Banks & UPS Units: Build your own smart battery backup systems with integrated LiPo charging and boosting.
