The STEVAL-ISA070V1 is a demo board based on the ST1S31 switching regulator in SO-8 package. The ST1S31 is an internally compensated 1.5MHz fixed frequency PWM synchronous step down regulator. The regulator operates from 2.8V to 5.5V input, while it regulates an output voltage as low as 0.8V and up to VIN. The ST1S31 integrates a 60mohm high side switch and 45mohm synchronous rectifier allowing very high efficiency with very low output voltages. The peak current mode control with internal compensation delivers a very compact solution with a minimum component count.

• 3A peak output current
• Internal soft start and enable
• All ceramic capacitors
• Power good (POR)
• Cycle by cycle current limiting
• Current foldback short circuit protection
