Overview
NX2155H Single Power Supply Synchronous PWM Controller Description The NX2155H controller IC is a single input supply synchronous Buck controller IC designed for step down DC to DC converter applications.
The NX2155H is optimized to convert bus voltages from 8V to 22V to output as low as 0.
8V voltage.
An internal regulator converts the bus voltage to 5V, which provides voltage supply to internal logic and driver circuits.
The NX2155H operates at a programmable frequency of 2MHz, and employs loss-less current limiting by sensing the Rdson of synchronous MOSFET followed by hiccup feature.
Feedback undervoltage triggers the Hiccup mode.
Other features of the device are: Internal Schottky diode...
