Pb Free Product  
FEATURES  
DESCRIPTION  
The NX2155H controller IC is a single input supply syn-  
chronous Buck controller IC designed for step down DC  
to DC converter applications. NX2155H is optimized to  
convert bus voltages from 8V to 22V to output as low as  
0.8V voltage. An internal regulator converts bus voltage  
to 5V, which provides voltage supply to internal logic  
and driver circuit. The NX2155H can operates at pro-  
grammable frequency of 2MHz and employs loss-less  
current limiting by sensing the Rdson of synchronous  
MOSFET followed by hiccup feature.Feedback under  
voltage triggers Hiccup.
