The NCV33163 series are monolithic power switching regulators that contain the primary functions required for DC−to−DC converters.
This series is specifically designed to be incorporated in step−up, step−down, and voltage−inverting applications with a minimum number of external components.
These devices consist of two high gain voltage feedback comparators, temperature compensated reference, controlled duty cycle oscillator, driver with bootstrap capability for increased efficiency, and a high current output switch. Protective features consist of cycle−by−cycle current limiting, and internal thermal shutdown.
Also included is a low voltage indicator output designed to interface with microprocessor based systems.
These devices are contained in a 16 pin dual−in−line heat tab plastic package for improved thermal conduction.
