Description  
Enable  
The ST1S40 is an internally compensated 850  
kHz fixed-frequency PWM synchronous step-  
down regulator. ST1S40 operates from 4.0 V to  
18 V input, while it regulates an output voltage as  
Cycle-by-cycle current limiting  
Current fold back short-circuit protection  
VFQFPN4x4-8L, HSOP-8, and SO-8 and  
low as 0.8 V and up to V .  
packages  
IN  
The ST1S40 integrates a 95 mΩ high side switch  
and 69 mΩ synchronous rectifier allowing very  
high efficiency with very low output voltages.  
Applications  
μP/ASIC/DSP/FPGA core and I/O supplies  
The peak current mode control with internal  
compensation delivers a very compact solution  
with a minimum component count.  
Point of load for: STB, TVs, DVD  
Optical storage, hard disk drive, printers,  
audio/graphic cards  
The ST1S40 is available in VFQFPN 4 mm x 4  
mm 8 lead package, HSOP-8 and standard SO-8.
