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.

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.
