NB680A Overview
The NB680A is a fully integrated, highfrequency, synchronous, rectified, step-down, switch-mode converter with a fixed 3.36V Vout and low-power mode voltage scaling. It offers a very pact solution to achieve an 8A continuous output current and a 10A peak output current over a wide input supply range with excellent load and line regulation. The NB680A operates at high efficiency over a wide output current load range...
