Description

The STEVAL-ISA070V1 demonstration board is based on the ST1S31, an internally compensated 1.5 MHz fixed-frequency PWM synchronous step-down regulator. This device operates from 2.8 V to 5.5 V input, while it regulates an output voltage as low as 0.8 V and up to Vin.

The peak current mode control with internal compensation delivers a very compact solution with a minimum component count.

Features
■ 4 A peak output current
■ 2.8 V to 5.5 V input voltage
■ Output voltage adjustable from 0.8 V
■ 1.5 MHz switching frequency
■ Internal soft-start and enable
■ Integrated 60 mΩ and 45 mΩ power MOSFETs
■ All ceramic capacitor
■ Power Good (POR)
■ Cycle-by-cycle current limiting
■ Current foldback short-circuit protection
■ RoHS compliant
