The ISL6406EVAL3, ISL6406EVAL2 and ISL6406EVAL1 evaluation boards highlight the operation of the ISL6406 adjustable frequency, synchronous buck switching regulator in an embedded application. Each evaluation board is shipped "ready to use" right from the box. The board accepts a 3.3V input from a standard power supply. The output can be exercised through the use of an external load. Additionally, there are posts available on the board for introducing power to the board and for drawing current from the regulated output. Two probe points are also available, which provide kelvin connections to CPVOUT (TP1) and CT1 (P6).
