Lemontree

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

STEVAL-ISA089V1

 
Overview

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.

Main features

  • Max output current: 1.5 A
  • Output voltage from 1.235 V to 35 V
