A Buck converter is a type of switching regulator. It is also known as a step-down converter, where the input voltage is “stepped down” from a higher voltage to a lower output voltage. The Buck converter also maintains, or regulates, this new output voltage at the desired level. The operating voltage requirements of different electronic devices can vary widely. A stable voltage needs to be supplied for each of these devices, thus requiring the use of Buck converters. A synchronous Buck converter uses integrated power MOSFETs as its switching elements. This is portrayed as Q1, the high-side FET, and Q2, the low-side FET, in the picture here. Additional external passive elements like an inductor and capacitor are used to store energy for proper operation. The AP6xxxx family of parts is the nomenclature of Diodes’ new generation of synchronous Buck converters.
