In summary, when comparing the power module with the discrete power design approach, there are many advantages to the module approach. Minimal design time is required, which saves hundreds of man hours in development, procurement and PCB layout. Layout risk is eliminated, as Renesas provides the PCB design files for the board layout. The modules allow high density power designs in very small PCB board area without heat sinks or fans. Since the ISL8203M is a fully integrated solution, the BOM cost is much less and the procurement time is reduced. Renesas guarantees the operation, as each module is fully tested. The package supports pick and place for high volume manufacturing. Design support, including application notes, evaluation boards, iSim (schematic capture and simulation), and the PCB board layout files for guaranteed operation are offer by Renesas. The discrete power supply point-of-load designs for driving multiple voltage rails can be tedious, time consuming, and difficult in the development time, procurement and PCB layout. Power modules provide all of the essential power blocks such as the power MOSFETs, power inductor and compensation network in a small package without the requirement for heat sinks or cooling fans. For multiple voltage rails, the power modules are the easiest approach to meet any power requirement.
