DESCRIPTION

The L4960 is a monolithic power switching regula-

tor delivering 2.5A 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 operation mode.

HEPTAWATT

BLOCK DIAGRAM

The L4960 is mounted in a Heptawattplastic power

package and requires very few external compo-

nents.

Efficient operation at switching frequencies up to

150KHz allows a reduction in the size and cost of

external filter components.
