Description

The ST1S06 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 1.5A

over an input voltage range of 2.7V to 6V. An high

switching frequency (1.5MHz) allows the use of

tiny surface-mount components: as well as the

resistor divider to set the output voltage value,

only an inductor and two capacitors are required.

Besides, a low output ripple is guaranteed by the

current mode PWM topology and by the use of low

E.S.R. SMD ceramic capacitors. The device is

thermal protected and current limited to prevent

damages due to accidental short circuit. The

ST1S06 is available in DFN6 3x3 package.
