USES TINY CAPACITORS AND INDUCTORS  
AVAILABLE IN DFN 3x3 EXPOSED PAD  
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, a schottky diode 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 ST1S03 is  
available in DFN6 package.

DESCRIPTION  
The ST1S03 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 3V to 16V. An high
