We certainly do, so we've designed the SparkFun BabyBuck Regulator Breakout to help us with just such a task. Featuring the AP63203 from Diodes Inc, this breakout board takes advantage of a 2A synchronous buck converter that has a wide input voltage range of 3.8V to 32V and fully integrated 125mΩ high-side power MOSFET/68mΩ lowside power MOSFET to provide high-efficiency step-down DC/DC conversion. All of this snuggled up in a low-profile, TSOT26 package that's integrated into a 0.4in by 0.5in board.Unlike it's sibling, the BabyBuck sacrifices power option flexibility for space. Don't worry, though, because you can still use the plated through holes for input and output power. With some simple right-angle headers, you'll be up and running in no time.Frequency Spread Spectrum (FSS) reduces EMI and a proprietary gate driver scheme resists switching node ringing without sacrificing MOSFET turn-on and turn-off times, which further erases high-frequency radiated EMI noise.Get Started with the SparkFun Buck Regulator Hookup GuideFeatures:\nLow-Profile Footprint\nVIN 3.8V to 32V\nVOUT 3.3V\nUp to 2A Continuous Output Current\n0.8V ± 1% Reference Voltage\n22µA Ultralow Quiescent Current\nSwitching Frequency - 1.1MHz\nSupports Pulse Frequency Modulation (PFM) \nUp to 80% Efficiency at 1mA Light Load\nUp to 88% Efficiency at 5mA Light Load\n\n\nFixed Output Voltage - 3.3V\nProprietary Gate Driver Design for Best EMI Reduction\nFrequency Spread Spectrum (FSS) to Reduce EMI\nPrecision Enable Threshold to Adjust UVLO\nProtection Circuitry \nOvervoltage Protection\nCycle-by-Cycle Peak Current Limit\nThermal Shutdown\n\n\nDocuments:\nSchematic\nEagle Files\nDimensional Drawing\nHookup Guide\n\nDatasheet (AP63203)\nGitHub Hardware Repo\nVideos","vendor":"SparkFun","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":3279,"title":"Default Title","sku":"SF-COM-18357","price":9.71,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
