Description

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 VCC.
