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 are contained in a 16 pin dual–in–line heat tab plastic
package for improved thermal conduction.
