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.
