Output voltage can be dynamically changed  
Internal Boost Schottky Diode  
The NX2147 controller IC is a step down switching con-  
troller with ability to dynamically adjust the output volt-  
age designed for applications such as Graphic Proces-  
sor Core voltage in Notebook PC products. It allows  
this by adjusting the reference input of the PWM  
comprator as oppose to the traditional method of feed-  
back adjustment. This device has three mode of opera-  
tions; a) Constant ON Time Synchronous Mode, b) Non  
Synchronous PFM mode or c) Ultrasonic PFM mode of  
operation. When selected in Non Synchronous mode,  
the device automatically disables the synchronous  
MOSFET in order to improve efficiency at light load.  
This device provides excellent dynamic response and  
nearly constant frequency for operation from 4.5V to  
24V of input voltage operation. Other features of the  
device are; internal logic level signal MOSFETs for out-  
put dynamic voltage adjustment, internal boost schotcky  
diode, less than 1uA VIN shutdown current, adjustable  
current limiting using lower MOSFET Rds-On and feed-  
back UVLO followed by latchdown, overvoltage protec-  
tion , internal digital soft start and soft stop shutdown  
using and internal 20 ohm MOSFET pull down.  
Ultrasonic mode operation available  
Bus voltage operation from 4.5V to 24V  
Less than 1uA VIN shutdown current with Enable  
low  
Excellent dynamic response with constant on time  
control  
Selectable between Synchronous CCM mode and  
diode emulation mode to improve efficiency at  
light load  
Programmable switching frequency  
Current limit and FB UVLO with latch off  
Over voltage protection with latch off  
Pb-free and RoHS compliant
