It’s pin-compatible with LM1117-3.3V TO-220, includes an enable pin, and comes assembled with header for breadboarding.\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e\n\u0026lt;\u0026gt;\n\u003cp\u003eSort out your power supply headaches with this Adafruit 3.3V Buck Converter Breakout, designed to efficiently power low-voltage circuits from a single Li-Ion cell or USB power. The onboard converter can supply up to 600mA load current across an input range of 3.5V to 5.5V, making it a great fit for portable builds and battery-powered projects.\u003c\/p\u003e\n\u003cp\u003eIt’s designed to be pin-compatible with the LM1117-3.3V TO-220, so you can swap it in as a drop-in upgrade for much better performance — with 90–95% efficiency. There’s also an EN (Enable) pin, which you can pull low to shut the output off completely.\u003c\/p\u003e\n\u003cp\u003eThe converter runs at a fixed 2MHz switching frequency in PWM mode, and it also supports PFM mode to help extend battery life by reducing current draw during light loads or standby operation.\u003c\/p\u003e\n\u003cp\u003eSupplied as a fully assembled and tested breakout board, with header included so you can plug it straight into a breadboard.\u003c\/p\u003e\n\u003cp\u003e\u003ciframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/uSBgcaizZNk?si=5knGzHbe-2jGcQDa\u0026amp;start=99\" title=\"YouTube video player\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eWeight: 0.9g\u003c\/li\u003e\n\u003cli\u003eDimensions: 16mm x 10mm x 3mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDatasheet\u003c\/li\u003e\n\u003cli\u003eEagleCAD files on GitHub\u003c\/li\u003e\n\u003cli\u003eFritzing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePackage Contents\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1x LM3671 3.3V Buck Converter Breakout - 3.3V Output 600mA Max\u003c\/li\u003e\n\u003cli\u003e1x 6-pin header\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":48623661809882,"sku":"yys1789674987490","price":5.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0824\/8318\/3834\/files\/lm3671-33v-buck-converter-breakout---33v-output-600ma-max_1.jpg?v=1789674991","url":"https:\/\/memoryfoamwear.shop\/products\/lm3671-33v-buck-converter-breakout-33v-output-600ma-max","provider":"My Store","version":"1.0","type":"link"}
