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.

MARKING

DIAGRAMS

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.

Protective features consist of cycle−by−cycle current limiting,

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

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