ST1S30  
3 A, 1.5 MHz PWM step-down switching regulator  
with synchronous rectification  
Features  
1.5 MHz fixed frequency PWM with current  
control mode  
3 A output current capability  
Typical efficiency: > 90%  
2 % DC output voltage tolerance  
Two versions available: power good or inhibit  
Integrated output over-voltage protection  
DFN8 (4 x 4 mm)  
Non switching quiescent current: (typ) 1.5 mA  
over temperature range  
R  
(typ) 100 mΩ  
DSon  
Moreover, since the required synchronous  
rectifier is integrated, the number of the external  
components is reduced to minimum: a resistor  
divider, an inductor and two capacitors. The  
Power Good function continuously monitors the  
output voltage. An open drain Power Good flag is  
released when the output voltage is within  
regulation. In addition, a low output ripple is  
guaranteed by the current mode PWM topology  
and by the use of low ESR SMD ceramic  
Utilizes tiny capacitors and inductors  
Operating junction temp. -25 °C to 125 °C  
Available in DFN8 (4 x 4 mm) exposed pad  
Description  
The ST1S30 is a step-down DC-DC converter  
optimized for powering low output voltage  
applications. It supplies a current in excess of 3 A  
over an input voltage range from 2.7 V to 6 V.  
capacitors. The device is thermally protected and  
the output current limited to prevent damages due  
to accidental short circuit. The ST1S30 is  
available in the DFN8 (4 x 4 mm) package.  
A high PWM switching frequency (1.5 MHz)  
allows the use of tiny surface-mount components.
