NCP3121  
Dual 3.0 A, Step-Down  
DC/DC Switching Regulator  
The NCP3121 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 NCP3121 provides  
dual 3.0 A switching regulators with an adjustable 200 kHz 750 kHz  
switching frequency. The switching frequency is set by an external  
resistor. The NCP3121 also incorporates an autotracking and  
sequencing feature. Protection features include cyclebycycle  
current limit and undervoltage lockout (UVLO). The NCP3121 comes  
in a 32pin QFN package.
