MOTOROLA ANALOG IC DEVICE DATA
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 digital telephone
systems, they can be used cost effectively in many other applications.
