MC34166, MC33166

3.0 A, Step−Up/Down/

Inverting Switching

Regulators

The MC34166, MC33166 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.
