DESCRIPTION  
The L4962 is a monolithic power switching regula-  
tor delivering 1.5A at a voltage variable from 5V to  
40V in stepdown configuration.  
The L4962is mountedina16-lead Powerdipplastic  
packageand Heptawatt packageand requiresvery  
few external components.  
Features of the device include current limiting, soft  
start, thermal protection and 0 to 100% duty cycle  
for continuous operating mode.  
Efficient operation at switching frequencies up to  
150KHz allows a reduction in the size and cost of  
external filter components.
