Adafruit MiniBoost 5V @ 1A - TPS61023

Key Features: 1.8-V Minimum input voltage for start-up Two 47-mOhm (LS) / 68-mOhm (HS) MOSFETs 3.7-A Valley switching current limit Output short-circuit protection Auto PFM operation mode at light load This adorable little board will come in very handy whenever you need a good amount of 5V power. It's the size of a linear regulator, but it's actually a mini-booster! Input 2-5VDC on one side, and get 5V at up to 1A supply on the other. Perfect for use with battery-powered projects with 2 or 3 Alkaline, or a single Lithium battery.This booster uses a very small but thermally efficient chip from TI, the TPS61023. This chip has nearly everything integrated, including dual 3A MOSFET switches. Note that the switch doesn't tell you the max output, see the tables below for that!We set the feedback resistors to give a 5.2V output, this is a little higher than 5V which helps account for voltage drop over cables.Item Specifics1 - Breakout Board1 - 0.1" headerInput voltage range: 0.5 V to 5.5 V?1.
