The L4964 is a step-down power switching regulator delivering 4A at a voltage variable from 5.1V to 28V. Features of the device include overload protection, soft start, remote inhibit, thermal protection, a reset output for microprocessors, and a PWM comparator input for synchronization in multichip configurations. The L4964 is mounted in a 15-lead Multiwatt) plastic power package and requires very few external components. Efficient operation at switching frequencies up to 120kHz allows a reduction in the size and cost of external filter components.
