ST1S06 Description
The ST1S06xx is a step down DC-DC converter optimized for powering low-voltage digital core in HDD applications and, generally, to replace the high current linear solution when the power dissipation may cause an high heating of the application environment. It provides up to 1.5 A over an input voltage range of 2.7 V to 6 V. An high switching frequency (1.5 MHz) allows the use of tiny surface-mount ponents:.
