ORDERING INFORMATION- -
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. Current Mode Operation to 300 kHz Automatic Feed Forward Compensation Latching PWM for Cycle–by–Cycle Current Limiting Continuous Retry after Fault Timeout Soft–Start with Maximum Peak Switch Current Clamp Internally Trimmed 2% Bandgap Reference High Current Totem Pole Driver Input Undervoltage Lockout Low Startup and Operating Current Direct Interface with Motorola SENSEFET Products
