The NX9511B is synchronous buck switching converter in multi chip module designed for step down DC to DC converter applications. They are optimized to convert bus voltages from 2V to 25V to as low as 0.8V output voltage. The output current can be up to 9A. The NX9511B offer an Enable pin that can be used to program the converter's start up. NX9511B operates at fixed internal frequency of 1MHz and employ loss-less current limiting protection by sensing the Rdson of synchronous MOSFET followed by latch out feature. Feedback under voltage triggers Hiccup.
