The ISL6539EVAL1, ISL6539EVAL2 boards evaluate the ISL6539 wide input range dual pwm controller with DDR option. The board kit includes the application note, ISL6539 datasheet, and evaluation board. The evaluation board supports testing with laboratory power supplies. Both regulated outputs can be exercised through external loads. There are posts available on the two regulated output rails for drawing a load and/or monitoring the voltages.
The ISL6539EVAL2 has two LEDs which indicate the status of the individual channel PGOOD signals. There are also four scope probe points that allow for in depth analysis. Four jumpers have also been provided for control and monitoring purposes.
