MC34163DWG Buck Boost Regulator 16-Pin SOIC-W

The MC34163 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, a controlled duty cycle oscillator, a 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.
