DESCRIPTION

The L4962 is a monolithic power switching regula-

tor delivering 1.5A at a voltage variable from 5V to

40V in step down configuration.

Features of the device include current limiting, soft

start, thermal protection and 0 to 100% duty cycle

for continuous operating mode.

The L4962 is mounted in a 16-lead Powerdip plastic

package and Heptawatt package and requires very

few external components.

Efficient operation at switching frequencies up to

150KHz allows a reduction in the size and cost of

external filter components.
