TPS61090 Power Boost Charger 1000C

The PowerBoost 1000C is a DC/DC boost converter module designed to power portable projects with a load-sharing battery charger circuit. It can be powered by a 3.7V LiIon/LiPoly battery and convert the battery output to 5.2V DC for running 5V projects. With a TPS61090 boost converter chip, it offers low battery detection, synchronous conversion, and high efficiency. The PowerBoost 1000C includes a smart load-sharing Lipoly charger that automatically switches over to USB power when available, making it ideal for uninterrupted power supply. It also features a low battery indicator LED and charge-rate “iOS” data resistors.
