SparkFun 5V Buck Regulator Breakouts - AP63357
========================================
These buck regulator boards feature the AP63357 from [Diodes Inc.](https://www.diodes.com/), a 3.5A synchronous buck converter with a wide input voltage range of 3.8V to 32V. The fully integrated 74mΩ high-side power MOSFET/40m low-side power MOSFET provide a high-efficiency step-down DC/DC conversion. The boards are configured to provide a regulated **5V** output and feature a high-voltage `EN` *(enable)* control pin that is rated up to 32V. The boards also include 0.1" spaced PTH pins to connect the input and output power and a copper pad is provided to attach a heat sink to the bottom of the board; to dissipate excess heat.

| The [Buck regulator breakout board](https://www.sparkfun.com/products/21255), has additional options for connecting input and output power. There is a pre-assembled screw terminal for a non-permanent connection and the option to solder on a [barrel jack](https://www.sparkfun.com/products/119) for an [external power supply](https://www.sparkfun.com/categories/308). The board also includes and red, power indication LED for when the power output is enabled. | Unlike its sibling, the [BabyBuck](https://www.sparkfun.com/products/21256) is a minimalistic board that sacrifices the connection options for space. Don't worry, though, because the PTH pins are still available to connect the input and output power. All of this snuggled up in a low-profile, .63" x .52" board. |
