STEVAL-ISA089V1
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 STEVALISA089V1 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.
