STEVAL-ISA089V1

1.5 A step-down switching regulator based on the L5972D

Features

■ Max output current: 1.5 A

■ Output voltage from 1.235 V to 35 V

■ Operating input voltage from 4.4 V to 36 V

■ Internal switching frequency: 250 kHz

■ Synchronization pin for cases where a higher

frequency (up to 500 kHz) is required

■ Short-circuit protection

■ Inhibit pin

■ Thermal shutdown

■ RoHS compliant

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 VCC.
