CN0190 is a reference solution for multivoltage power systems. The design can easily be adapted to customer requirements and provides the most popular system voltages. The circuit uses an optimum combination of switching and linear regulators to provide an overall efficiency of approximately 78% when the outputs are fully loaded. Output power delivered under full load is approximately 25 W.
The circuit supplies most of the typical power rails required for digital and analog circuits and also demonstrates an easy way to realize overvoltage, undervoltage, and overcurrent detection and protection. In addition, this module shows how to implement sequencing and power margining control.
The circuit is flexible and can accept a wide input voltage range from 6 V to 14 V. This is possible because the highly efficient switching controllers and regulators used in the first stage of each power rail have correspondingly wide input ranges. The ADM1178 block provides overvoltage and overcurrent detection and protection for the input supply, as well as hotswap control for the whole system. The ADM1066 offers a single-chip solution for power supply monitoring and sequencing control for all of the 12 power rails and also margining control for the 3.3V(2A) rail.
