of products is synchronous Buck controller IC 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. These products operate at fixed internal frequency of 300kHz, except that NX2120 operates at 300kHz and n n n n n n 2120A at 600kHz frequency. These products employ lossless current limiting protection by sensing the Rdson of n synchronous MOSFET followed by latch Feedback under voltage triggers Hiccup. out feature.
