HIGH PERFORMANCE  
The MC34129/MC33129 are high performance current mode switching  
regulators specifically designed for use in low power digital telephone  
applications. These integrated circuits feature a unique internal fault timer  
that provides automatic restart for overload recovery. For enhanced system  
efficiency, a start/run comparator is included to implement bootstrapped

reference, reference amplifier, fully accessible error amplifier, sawtooth  
oscillator with sync input, pulse width modulator comparator, and a high  
current totem pole driver ideally suited for driving a power MOSFET.  
Also included are protective features consisting of soft–start,  
undervoltage lockout, cycle–by–cycle current limiting, adjustable deadtime,  
and a latch for single pulse metering.
