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
DFN6 (3x3mm)
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.
