NCP3120  
Dual 2.0 A, Step-Down  
DC/DC Switching Regulator  
The NCP3120 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 NCP3120 provides  
dual 2.0 A switching regulators with an adjustable 200 kHz - 750 kHz  
switching frequency. The switching frequency is set by an external  
resistor. The NCP3120 also incorporates an auto-tracking and  
sequencing feature. Protection features include cycle-by-cycle  
current limit and undervoltage lockout (UVLO). The NCP3120 comes  
in a 32-pin QFN package.
