SparkFun AP63203 Buck/BabyBuck Regulator Breakouts are 2A synchronous buck converter boards that operate at 3.8V to 32V wide input voltage range. These breakouts integrate a 125mΩ high-side and a 68mΩ low-side power MOSFET that provides high-efficiency step-down DC/DC conversion. The AP63203 breakout regulators feature a proprietary gate driver design and Frequency Spread Spectrum (FSS) for Electromagnetic Interference (EMI) reduction. These regulator breakouts offer 0.8V ±1% of the reference voltage, 22µA ultralow quiescent current, and 3.3V output voltage. The Buck regulator is available in a 1-inch x 1-inch board and the BabyBuck regulator is available in a 0.4-inch x 0.5-inch board.
