Produktbeskrivning
The SparkFun 5V Buck Regulator Breakout features the AP63357 from Diodes Inc., a 3.5A synchronous buck converter with a wide input voltage range of 3.8V to 32V. The fully integrated 74mO high-side power MOSFET/40mO low-side power MOSFET provides a high-efficiency step-down DC/DC conversion.
This full-size, 1in. x 1in. version of our buck regulator boards is configured to provide a regulated 5V output (from a 6 to 32V input voltage range) and features a high-voltage EN (enable) control pin that is rated up to 32V. On the back of the board, a small copper pad is available to dissipate excess heat with a heat sink.
As a full-size buck regulator breakout, additional options for connecting input and output power. There is a pre-assembled screw terminal for a non-permanent connection, the option to solder on a barrel jack for an external power supply, and five PTH pins to create a more permanent installation. Our full-size buck regulators also come with a red, power indication LED that light up when the power output is enabled and two mounting holes compatible with 4-40 hardware.
Note: While the AP63357 is rated up to a 3.5A output, users should expect a 3A maximum with our boards due to thermal constraints. The boards can output 3.5A but would require a sufficient amount of active cooling.
