L4960 Datasheet PDF - STMicroelectronics

DESCRIPTION
The L4960 is a monolithic power switching regulator 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.
TheL4960 is mountedina Heptawattplastic power 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.
