Product Summary

The MC33167T is a high performance fixed frequency power switching regulator that contains the primary functions required for dc-to-dc converters. This MC33167T was 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. The MC33167T consists of an internal temperature compensated reference, fixed frequency oscillator with on–chip timing components, latching pulse width modulator for single pulse metering, high gain error amplifier, and a high current output switch.
