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 components and can also be used cost effectively in step−up applications.
These devices consist 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.
