FEATURES  
DESCRIPTION  
D
60-mΩ MOSFET Switches for High Efficiency  
at 3-A Continuous Output Source or Sink  
Current  
0.9-V to 3.3-V Adjustable Output Voltage With  
1% Accuracy  
Externally Compensated for Design Flexibility  
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 members of the SWIFT family of dc/dc regulators,  
the TPS54310 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 provides high performance  
under transient conditions; an undervoltage-lockout  
circuit to prevent start-up until the input voltagereaches  
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.

The TPS54310 device is available in a thermally  
enhanced 20-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.
