com MC34129 MC33129 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 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.
Although these devices are primarily intended for use in...
