Product description: SparkFun Buck Regulator Breakout - step-down converter 5 V 3 A - AP63357 - SparkFun COM-21255

Step-down converter equipped with the AP63357 voltage regulator by Diodes Inc. It lowers the input voltage from 6 V to 32 V, giving the output voltage 5 V, current efficiency is 3 A. The module has a fully integrated 74 mOhm MOSFET on the high side and a 40 mOhm MOSFET on the low side, providing highly efficient DC-DC conversion. At the back of the module, the manufacturer placed a copper washer that dissipates excess heat generated by the plate during operation.

The manufacturer has prepared a detailed user's guide that makes it much easier to start working with SparkFun Buck Regulator Breakout - check it out!

SparkFun Buck Regulator Breakout has screw connections and outputs in the form of soldering pads

SparkFun Buck Regulator Breakout has screw connections and outputs in the form of soldering pads.

Pin description

The board has outputs in the form of solder pads, to which wires should be soldered and connected according to the following dependencies:

  • VIN - input voltage from 6 V to 32 V
  • GND - system ground
  • VOUT - output voltage (adjustable 5 V)
  • EN - high voltage control pin

In addition, the module also has a screw connection as an alternative connection.

Technical specification of the converter

  • Inverter type: step-down
  • Input voltage: 6V to 32V
  • Output voltage: 5V
  • Continuous output current: 3 A (according to the specification, the system has a current efficiency of 3.5 A, however, the manufacturer notes that due to the high heating of the module, this value may not be achievable)
  • Reference voltage: 0.8V ± 1%
  • Quiescent current: 22 µA
  • Switching frequency: 450kHz
  • Supports pulse frequency modulation (PFM): up to 86% efficiency at 5 mA load
  • Patented design provides the best EMI reduction
  • Frequency Spread Spectrum (FSS) for EMI reduction
  • LDO mode
  • Security:
    • undervoltage lockout (UVLO)
    • undervoltage outputs (UVP)
    • cycle-by-cycle peak current limit
    • thermal shutdown
In the rear part of the module there is an element dissipating the generated heat.
