FEATURES  
DESCRIPTION  
D
Tracks Externally Applied Reference Voltage  
As a member of the SWIFTfamily of dc/dc regulators,  
the TPS54872 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 3.8 V; an internally set  
slow-start circuit to limit in-rush currents; and a status  
output to indicate valid operating conditions.

APPLICATIONS  
The TPS54872 is available in a thermally enhanced  
28-pin TSSOP (PWP) PowerPADpackage, 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.
