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.

POWER SWITCHING

REGULATORS

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.

SEMICONDUCTOR

TECHNICAL DATA

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 µA.
