L4964 Step-Down, adj., 9...36 V, 5.1...28 V, Multiwatt-15

The L4964 is a step-down switching regulator that delivers 4A at a variable voltage of 5.1 V to 28 V. 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 housed in a 15-pin multiwatt plastic package and requires very few external components. Efficient operation at switching frequencies up to 120 kHz enables a reduction in the size and cost of external filter components.
