{"title":"PowerBoost 500 Basic - 5V USB Boost @ 500mA from 1.8V+","handle":"powerboost-500-basic-5v-usb-boost-500ma-from-1-8v","url":"/products/powerboost-500-basic-5v-usb-boost-500ma-from-1-8v","description":"The PowerBoost 500 Basic is a compact DC/DC boost converter that takes input from 1.8V or higher and outputs a steady 5.2V — perfect for powering portable 5V projects from batteries. The slightly elevated 5.2V output provides headroom for cable resistance and high-current draws, preventing brown-outs while remaining safe for all 5V electronics.\n\nBuilt around the TI TPS61090 boost converter with synchronous conversion, the module delivers excellent efficiency (90%+) and includes a low-battery indicator LED. Each board comes with a loose USB-A jack for optional soldering.\n\nKey Features\n\n\n1.8V+ Input – Works with LiPo, NiMH, alkaline, and other battery types\n\n5.2V Regulated Output – Safe for all 5V devices with headroom for cable losses\n\n90%+ Efficiency – Synchronous conversion for minimal power waste\n\nLow Battery Indicator – Red LED lights when input drops below 3.2V\n\nEnable Pin – Completely disconnect output by pulling EN to ground\n\nUSB Charging Resistors – On-board 500 mA charge-rate data resistors\n\n\nSpecifications\n\n\nConverter IC: TI TPS61090\n\nInput Voltage: 1.8V+\n\nOutput Voltage: 5.2V DC\n\nOutput Current: 500 mA+ @ 1.8V, 750 mA+ @ 2.4V (2× NiMH), 1000 mA+ @ 3.7V (LiPo)\n\nInternal Switch: 2A (~2.5A peak)\n\nSwitching Frequency: 700 kHz\n\nQuiescent Current: 5 mA (enabled), 20 µA (disabled)\n\n\nIdeal For\n\nBattery-powered Arduino and Raspberry Pi projects\nPortable robotics\nWearable electronics\nField-deployed sensors and data loggers\n\n\nPackage Contents\n\n1× PowerBoost 500 Basic PCB (assembled and tested)\n1× USB-A Jack (loose, for optional soldering)\n\n\nResources\n\nTPS61090 Datasheet (TI)\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":13119,"title":"Default Title","sku":"AF-1903","price":20.18,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
