High Performance Current Mode Controllers
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 operation of VCC.
Other functions contained are a temperature compensated 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...
