Product Summary
The MC34167T is a high performance fixed frequency power switching regulator that contain the primary functions required for dc–to–dc converters. The MC34167T is specifically designed to be incorporated in step–down and voltage–inverting configurations with a minimum number of external components and can also be used cost effectively in step–up applications.
