NCP3122  
Dual 2.0 A, Step-Down  
DC/DC Switching Regulator  
The NCP3122 is a dual buck converter designed for low voltage  
applications requiring high efficiency. This device is capable of  
producing an output voltage as low as 0.8 V. The NCP3122 provides  
dual 2.0 A switching regulators with an adjustable 200 kHz 2200  
kHz switching frequency. The switching frequency is set by an  
external resistor. The NCP3122 also incorporates an autotracking  
and sequencing feature. Protection features include cyclebycycle  
current limit and undervoltage lockout (UVLO). The NCP3122 comes  
in a 32pin QFN package.
