MARKING  
The NCP3063 Series is a higher frequency upgrade to the popular  
MC34063A and MC33063A monolithic DC−DC converters. These  
devices consist of an internal temperature compensated reference,  
comparator, a controlled duty cycle oscillator with an active current  
limit circuit, a driver and a high current output switch. This series was  
specifically designed to be incorporated in Step−Down, Step−Up and  
Voltage−Inverting applications with a minimum number of external  
components.
