In summary, the LM27403 from TI enables a high performance DC power solution without a high end solution price. This has been achieved by several advanced features including the DCR temperature compensation current limit utilizing a very simple low priced BJT. The LM27403 is compatible with the most common POL voltage rails including 3.3 V, 5 V, and 12 V. The ideal applications will be those that have a need for high efficiency, accurate current limit, and large loads > 25 A such as POL modules, FPGA power and DDR power to name a few. TI has also made it easier than ever to quickly implement a design from concept to reality by providing several design tools including a quick start calculator, Webench, and a growing list of functional reference designs including test reports at ti.com.
