AN2093 APPLICATION NOTE ST1S03 BUCK CONVERTERS FOR HDD POWER SUPPLIES 1.

ABSTRACT The ST1S03 is a step down DC-DC converter optimized for powering the low-voltage digital core in HDD applications and, generally, replacing the high current linear solution when the power dissipation may cause excessive heating of the application environment.

It provides up to 1.5A over an input voltage range of 3V to 16V.

A high switching frequency (1.5MHz) allows the use of tiny surface-mount components, as well
