FEATURES  
DESCRIPTION  
D
Low Voltage Separate Power Bus  
15-mΩ MOSFET Switches for High Efficiency  
at 9-A Continuous Output  
Adjustable Output Voltage  
Externally Compensated With 1% Internal  
Reference Accuracy  
Fast Transient Response  
Wide PWM Frequency:  
Adjustable 280 kHz to 700 kHz  
Load Protected at Thermal Shutdown  
Integrated Solution Reduces Board Area and  
Total Cost  
As a member of the SWIFTfamily of dc/dc regulators,  
the SN0401093 low-input voltage high-output current  
synchronous buck PWM converter integrates all  
required active components. Included on the substrate  
with the listed features are a true, high performance,  
voltage error amplifier that enables maximum  
performance under transient conditions and flexibility in  
choosing the output filter L and C components; an  
under-voltage-lockout circuit to prevent start-up until  
the VIN input voltage reaches 3 V; an internally and  
externally set slow-start circuit to limit in-rush currents;  
and a power good output useful for processor/logic  
reset, fault signaling, and supply sequencing.

APPLICATIONS  
The SN0401093 is available in a thermally enhanced  
28-pin TSSOP (PWP) PowerPADpackage, which  
eliminates bulky heatsinks.
