Description

Who doesn??t occasionally need power regulation? 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 125m?? high-side power MOSFET/68m?? low-side 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
