1.5 A step down switching regulator (Vin=4 to 36 V, Vout=1.235 to Vin) based on L5972D
  • active 活性

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 VCC.
