SLVS412DDECEMBER 2001REVISED FEBRUARY 2007  
3-V TO 6-V INPUT, 3-A OUTPUT SYNCHRONOUS-BUCK PWM  
SWITCHER WITH INTEGRATED FETs (SWIFT)  
FEATURES  
DESCRIPTION  
60-mMOSFET Switches for High Efficiency  
at 3-A Continuous Output Source or Sink  
Current  
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  
Adjustable Output Voltage Down to 0.9 V With  
1% Accuracy  
Externally Compensated for Design Flexibility  
Fast Transient Response  
provides  
high  
performance  
under  
transient  
conditions; an undervoltage-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.  
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  
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.  
APPLICATIONS  
Low-Voltage, High-Density Systems With  
Power Distributed at 5 V or 3.3 V  
Point of Load Regulation for High  
Performance DSPs, FPGAs, ASICs, and  
Microprocessors
