The small controller size of the ISL68200/01, coupled with the high performance of Renesas' R4 modulator, allows for exceptionally small overall design size. In this example reference design, the full supply, including controller, power stage, inductor, input caps, output caps, and supporting resistors and capacitors, fits in a space saving 13 mm x 13 mm footprint, giving a total area of 169 mm2. For size comparison, a US dime has a diameter of 18 mm and total area of 255 mm2. As boards become smaller and denser with ASICs, FPGAs and processors, small overall design size is becoming a critical design requirement.
