Using the EL7562 Demo Board
The EL7562 is a Buck (Step Down) DC:DC controller with integrated synchronous MOSFETs in a 16-pin QSOP package. With very few external components, a 2A step-down DC:DC converter can be very easily built, resulting in saved board space (0.5in2), minimal design effort, and improved design time.
There are 2 demo boards, one for nominal 5V input and another for 3.3V input. This document outlines the design consideration and lists the bill of materials and the layout. Please also refer to the advanced data sheet of EL7562 for detailed applications of the features.
