MC34166, MC33166

3.0 A, Step−Up/Down/

Inverting Switching

Regulators

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.

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.

undervoltage lockout, and thermal shutdown. Also included is a low

power standby mode that reduces power supply current to 36 mA.
