{"title":"Adafruit MiniBoost 5V @ 1A - TPS61023","handle":"adafruit-miniboost-5v-1a-tps61023","url":"/products/adafruit-miniboost-5v-1a-tps61023","description":"The Adafruit MiniBoost 5V @ 1A is a compact inductor-based boost converter that delivers up to 1 A of regulated 5 V output from a 2–5 V input. About the size of a linear regulator, it's perfect for powering microcontrollers, displays, and peripherals from a single LiPo battery or a pair of alkaline cells.\n\nBuilt around the TI TPS61023 with integrated dual 3 A MOSFET switches, this board achieves approximately 88% efficiency at typical loads and includes a true-disconnect enable pin that completely de-powers the output when pulled low. The output is set to 5.2 V to compensate for cable voltage drop. For lower-current needs, see the MiniBoost 100 mA Charge Pump.\n\nKey Features\n\n\n5.2 V Regulated Output – Slightly above 5 V to account for cable drop\n\nUp to 1 A Output – From a 3.5 V input (LiPo nominal); see output table below\n\nWide Input Range – 2–5 V DC (boots from as low as 2 V)\n\nHigh Efficiency – ~88% at loads up to 500 mA from 3.7 V input\n\nTrue Disconnect Enable – Pull EN low to completely de-power the output\n\nUltra-Compact – Similar footprint to a TO-220 linear regulator\n\nPre-Assembled – Fully soldered breakout board, just add header\n\n\nOutput Current by Input Voltage\n\n\n2.0 V in → 300 mA max at 5 V (minimum boot voltage)\n\n2.5 V in → 500 mA max (two NiMH cells)\n\n3.0 V in → 800 mA max (two alkalines or near-flat LiPo)\n\n3.5 V in → 1100 mA max (LiPo nominal voltage)\n\n4.0 V in → 1400 mA max (three NiMH or fresh LiPo)\n\n\nEfficiency at 3.7 V Input\n\n100 mA out → 160 mA in (88%)\n250 mA out → 400 mA in (88%)\n500 mA out → 800 mA in (88%)\n1000 mA out → 1800 mA in (78%)\n\n\nIdeal For\n\nLiPo/LiIon battery-powered projects needing 5 V\nPowering microcontrollers, servos, and small displays from battery\nPortable electronics with moderate current requirements\nProjects using 2–3 AA/AAA alkaline or NiMH cells\n\n\nPackage Contents\n\n1× Adafruit MiniBoost 5V @ 1A Breakout (assembled)\n1× Header strip\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2964,"title":"Default Title","sku":"AF-4654","price":7.93,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
