Shown here is an easy explanation on how the ISL8117/A makes a system designer’s life easy by making power supply design simple. There are three aspects of power supply design: component selection, circuit design and layout design. ISL8117/A makes design easy on all three fronts. Component selection: Once the ISL8117/A is selected, a designer may not need to select another controller for a different rail on the board or system because the ISL8117/A covers a wide range of input and output combinations. The ISL8117/A has a very low pin count and uses less external components. Its internal compensation and internal default design values further reduce the number of required external components. Circuit design: Less pins and fewer components directly translate to a less complicated circuit. Internal compensation reduces the design effort even further. Layout design: The ISL8117/A pin architecture has been designed in such a way that it can run on a bare minimum circuit for a basic buck converter. All additional function/feature pins have default values and can be sorted out without any additional components. All high power pins and signal pins are placed on opposite sides, therefore reducing any chance of interference. The ISL8117/A pins are organized to avoid layout errors by avoiding trace overlaps.
