STEVAL-ISA088V1:1 A step down switching regulator (Vin=4 to 36 V, Vout=1.235 to Vin) based on L5970D

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.
