NCP3163, NCV3163  
3.4 A, Step−Up/Down/  
Inverting 50−300 kHz  
Switching Regulator  
The NCP3163 Series is a performance enhancement to the popular  
MC33163 and MC34163 monolithic DC−DC converters. These  
devices consist of an internal temperature compensated reference,  
comparator, controlled duty cycle oscillator with an active current  
limit circuit, driver and high current output switch. This controller was  
specifically designed to be incorporated in step−down, step−up, or  
voltage−inverting applications with a minimum number of external  
components. The NCP3163 comes in an exposed pad package which  
can greatly increase the power dissipation of the built in power switch.
