FEATURES  
DESCRIPTION  
D
30-mΩ, 12-A Peak MOSFET Switches for High  
Efficiency at 6-A Continuous Output Source  
or Sink Current  
Adjustable Output Voltage Down To 0.9 V  
With 1.0% Accuracy  
As a member of the SWIFTfamily of dc/dc regulators,  
the TPS54610 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 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 or externally set slow-start circuit to limit  
inrush currents; and a power good output useful for  
processor/logic reset, fault signaling, and supply  
sequencing.  
D
D
Wide PWM Frequency:  
Fixed 350 kHz, 550 kHz or  
Adjustable 280 kHz to 700 kHz  
Synchronizable to 700 kHz  
Load Protected by Peak Current Limit and  
Thermal Shutdown  
Integrated Solution Reduces Board Area and  
Component Count  
D

The TPS54610 is available in a thermally enhanced  
28-pin TSSOP (PWP) PowerPADpackage, which  
eliminates bulky heatsinks. TI provides evaluation  
modules and the SWIFTdesigner software tool to aid  
in quickly achieving high-performance power supply  
designs to meet aggressive equipment development  
cycles.
