Overview: MC34167, MC33167 5.0 A, Step−Up/Down/ Inverting Switching Regulators
The MC34167, MC33167 series are high performance fixed frequency power switching regulators that contain the primary functions required for dc−to−dc converters. This series was specifically designed to be incorporated in step−down and voltage−inverting configurations with a minimum number of external ponents and can also be used cost effectively in step−up applications. These devices consist of an internal temperature pensated reference, fixed frequency oscillator with on−chip timing ponents, latching pulse width modulator for single pulse metering, high gain error amplifier, and a high current output switch.
