SWITCHER WITH INTEGRATED FETs (SWIFT )  
FEATURES  
DESCRIPTION  
D
15-mMOSFET Switches for High Efficiency  
at 9-A Continuous Output  
0.9-V to 2.5-V Adjustable Output Voltage  
Externally Compensated With 1% Accuracy  
Fast Transient Response  
Wide PWM Frequency:  
Fixed 350 kHz, 550 kHz or  
Adjustable 280 kHz to 700 kHz  
Load Protected by Peak Current Limit and  
Thermal Shutdown  
Integrated Solution Reduces Board Area and  
Total Cost  
As a member of the SWIFT family of dc/dc regulators,  
the TPS54910 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 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 TPS54910 is available in a thermally enhanced  
28-pin TSSOP (PWP) PowerPAD package, which  
eliminates bulky heatsinks. TI provides evaluation  
modules and the SWIFT designer software tool to aid  
in quickly achieving high-performance power supply  
designs to meet aggressive equipment development  
cycles.
