1 / 4 page Data brief For further information contact your local STMicroelectronics sales office. April 2011 Doc ID 018690 Rev 1 1/4 4 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.
