 | Kit Overview
Modern complex systems using various combinations of FPGAs, CPUs, DSPs, and analog circuits typically require multiple voltage rails. In order to provide high reliability and stability, the power system must not only provide the multiple voltage rails but also include proper sequencing control and necessary protection circuits.
The EVAL-CN0190-EB1ZEVAL-CN0190-EB1Z module 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.
This EVAL-CN0190-EB1ZEVAL-CN0190-EB1Z board 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 CN0190 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.
