Description

The STEVAL-ISA042V2 demonstration board is a step-down DC-DC converter optimized for powering the low-voltage digital core in HDD applications and, more generally, replacing the high-current linear solution when the power dissipation may cause excessive heating of the application environment. It provides up to 1.5 A over an input voltage range of 3 V to 16 V.

Features

■ Adjustable current-mode PWM step-down DC-DC converter

■ Output voltage, Vout : 3.3 V

■ Output current, Iout : 1.5 A

■ Internal compensation to eliminate additional components

■ Pulse skipping for Iout lower than 15 mA, to maintain the regulation with light loads

■ RoHS compliant
