The ISL8203M, for example, is a complete power supply in a package. Ideal for point of load (POL) applications where a step-down voltage is required from 3.3V or 5V, the ISL8203 is capable of producing two independent outputs each rated at 3A. It is possible to current share the device utilizing a current mode control loop, thus allowing the two outputs to be combined to a single 6A output. With the QFN based module packaging, the full 6A output current can be delivered at ambient temperatures as high as 85°C without the need for heat sinks or fans. The ISL8203 provides a high power density design with minimal board space, and is offered in a small over molded 9mm x 6.5mm QFN package.
