9-A OUTPUT, 3-V TO 4-V INPUT 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 regulators,  
the TPS54972 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 3.0 V; an internally set slow-start  
circuit to limit in-rush currents; and a status output to  
indicate valid operating conditions.  
15-mMOSFET Switches for High Efficiency at  
9-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  
APPLICATIONS  
The TPS54972 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.
