SLVS430D–JUNE 2002–REVISED FEBRUARY 2005  
3-A OUTPUT TRACKING/TERMINATION SYNCHRONOUS PWM SWITCHER WITH  
INTEGRATED FETs (SWIFT™)  
FEATURES  
DESCRIPTION  
•
Tracks Externally Applied Reference Voltage  
As a member of the SWIFT™ family of dc/dc regu-  
lators, the TPS54372 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 undervoltage-lockout circuit to pre-  
vent start-up until the input voltage reaches 3 V; an  
internally and externally set slow-start circuit to limit  
in-rush currents; and a status output to indicate valid  
operating conditions.  
•
60-mΩ MOSFET Switches for High Efficiency  
at 3-A Continuous Output Source or Sink  
Current  
•
•
6% to 90% VI Output Tracking Range  
Wide PWM Frequency: Fixed 350 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 TPS54372 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 devel-  
opment cycles.  
APPLICATIONS  
•
DDR Memory Termination Voltage  
•
Active Termination of GTL and SSTL  
High-Speed Logic Families
