d to provide multi-rail power for use in products such as cable and satellite set-top boxes, VoIP gateways, cable modems, and other home connectivity products as well as a variety of industrial and general purpose applications. This electronic circuit power supply project based on the ISL9440 offer internal soft-start, independent enable inputs for ease of supply rail sequencing, and integrated UV/OV/OC/OT protections in a space conscious 5mmx5mm QFN package. This quad output circuit power supply project based on ISL9440 utilize internal loop compensation to keep minimum peripheral components for compact design and a low total solution cost. These device are implemented with current mode control with feed forward to cover various applications even with fixed internal compensations. This quad output circuit power supply require a 12 volt DC input voltage and will provide the following output voltages : 1. 5 volt at 6 amperes, 2. 5 volt at 6 amperes, 5 volt at 2 amperes and 3. 3 volt at 0. 5 ampere. As you can see in the schematic circuit, this quad-output electronic project power supply require few external electronic parts and is very easy to be designed.
