NX2113/2113A  
300kHz & 600kHz SYNCHRONOUS PWM CONTROLLER WITH  
PROGRAMMABLE BUS UVLO

FEATURES  
DESCRIPTION  
n Synchronous Controller in 10 Pin Package  
The NX2113 controller IC is a synchronous Buck con-  
troller IC designed for step down DC to DC converter  
applications. Synchronous control operation replaces the  
traditional catch diode with an Nch MOSFET resulting  
in improved converter efficiency. The NX2113 controller  
is optimized to convert bus voltages from 2V to 25V to  
outputs as low as 0.8V voltage using Enable pin to  
program the BUS voltage start up threshold. The NX2113  
operates at 300kHz while 2113A is set at 600kHz  
operation which together with less than 50 nS of dead  
band provides an efficient and cost effective solution.  
Other features of the device are:

n Internal 300kHz for 2113 and 600kHz for 2113A  
n Internal Digital Soft Start Function  
n Separated power ground and analog ground for  
extra noise filtering  
n Pb-free and RoHS compliant
