Description
The STEVAL-ISA089V1 demonstration board
provides a platform for evaluation of the L5972D,
a step-down monolithic power switching regulator
with a minimum switch current limit of 2 A capable
of delivering more than 1.5 A of DC current to the
load depending on application conditions.
The input supply voltage of the STEVAL-
ISA089V1 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_CC.
