IC is a single power supply syn- n chronous Buck controller IC designed for step down DC n to DC converter applications. NX2150 is optimized to n convert bus voltages from 5V to 24V to outputs as low n as 0.8V voltage. An internal regulator converts bus n voltage to 5V, which provides voltage supply to internal n logic and driver circuit. The NX2150 has programmable frequency feature and operates at 300kHz when Rt pin n is open. The NX2150 employs fixed loss-less current limiting by sensing the Rdson of synchronous MOSFET n followed by hiccup feature.Feedback under voltage trig- n gers Hiccup.
