NCP5422EVB:NCP5422 Dual Out-of-Phase Synchronous Buck Controller Evaluation Board with Current Limit
The NCP5422 evaluation board is a 4.0 in by 2.2 in two-layer printed circuit board. This demonstration circuit can be used to evaluate the performance and functionality of NCP5422, Dual Out-of-Phase Synchronous Buck Controller. With onw 12 V input, two independent synchronous Buck switching regulators provide 1.8 V/10 A and 1.5 V/10 A outputs. The NCP5422 controller contains all the circuitry required for teo independent Buck regulators and uses the V2™ control scheme to achieve the fastest possible transient response and best overall regulation, while using the least number of external components. Another feature of the NCP5422 is out-of-phase synchronizarion between the channels, which rduces the input filter requirement. The NCP5422 also provides under-vo;tage lockout, soft start, built-in adaptive FET non-overlap, and hiccup-node overcurrent protection.
