The STEVAL-ISA088V1 demonstration board 
provides a platform for evaluation of the L5970D, 
a step-down monolithic power switching regulator 
capable of delivering up to 1 A of current at output 
voltages from 1.2 V to 35 V.

The input supply voltage of the STEVAL-
ISA088V1 can range from 4.4 V to 25 V based on 
the rated voltage of the input capacitor, while the 
output voltage is adjustable from 1.235 V to V
