Description
The STEVAL-ISA042V1 demonstration board is a step-down DC-DC converter based on ST’s ST1S03 switching regulator, 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 DCDC converter
• Output voltage, Vout: 1.2 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
