{"title":"TPS62827 3.3V Buck Converter Breakout - 3.3V Output 2 Amp Max","handle":"tps62827-3-3v-buck-converter-breakout-3-3v-output-2-amp-max","url":"/products/tps62827-3-3v-buck-converter-breakout-3-3v-output-2-amp-max","description":"This little buck converter based on the TPS62827 is super handy, taking up to 5.5V input and providing a 3.3V output with up to 2A current. It's great for supplying power to hungry 3.3V voltage circuits from a range of battery or power options.  This chip provides up to 2 Amp load current across the entire input voltage range of 3.4 to 5.5V. It's not a huge range but does cover LiPoly batteries, 3 alkalines, and USB power.Great for your portable project, we made this \"pin compatible\" with the LM1117-3.3V TO-220 chip so you can swap it in for better performance (90-95% efficiency!) There's also an ENable pin, tie it low to shut down the output completely.The Adafruit TPS62827 Breakout runs at 2.2-MHz fixed-frequency. Even though the chip itself supports up to 4A, we found that 2 Amps or so was a good max to stick to for constant current draw and 3 Amps for temporary peak current draws. We did use a 2 oz copper double-layer PCB.If you need a wider input range, check out the 3.3V output MPM3610 breakout with up to 20V input!Comes with a fully assembled and tested breakout board.  We also include header to plug it into a breadboard.","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":3470,"title":"Default Title","sku":"AF-4920","price":12.72,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":73,"option1":"Default Title"}]}
