DESCRIPTION
The L4964 is a stepdown 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
plas-
tic 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 ex-
ternal filter components.
