Product description: AP63203 - step-down buck converter with screw connector - 3,3V 2A - SparkFun COM-18356

Voltage regulator in the form of a step-down converter, made by SparkFun. AP63203 converter is designed to change input voltage from 3,8V to 32V to output: 3,3 V. Its current capability is 2 A with a fully integrated 125 mΩ MOSFET on the high side and a 68 mΩ MOSFET on the low side, providing highly efficient DC-DC conversion. All components are housed on a low profile board and enclosed in a TSOT26 enclosure. Voltage input / output can be provided in two ways: using screw connectors available on the board, or through holes with marked pins, where you can solder, for example, goldpin pins. In addition, the manufacturer has prepared a place on the bottom of the board where you can glue a heatsink to dissipate any heat from the board.

In our shop's assortment there are also other step-down converters available, as well as step-up and step-up / step-down converters.
