Qualified for Automotive Applications  
Power-Up/Down Tracking for Sequencing  
As a member of the SWIFTfamily of dc/dc regulators,  
the TPS54380 low-input voltage, high-output current,  
synchronous buck PWM converter integrates all  
required active components. Using the TRACKIN pin  
with other regulators, simultaneous power up and down  
are easily implemented. Included on the substrate with  
the listed features are a true, high-performance, voltage  
error amplifier that enables maximum performance and  
flexibility in choosing the output filter L and C  
components; an undervoltage-lockout circuit to prevent  
start-up until the input voltage reaches 3 V; an internally  
or externally set slow-start circuit to limit inrush  
currents; and a power-good output useful for  
processor/logic reset.

The TPS54380 is available in a thermally enhanced  
20-pin TSSOP (PWP) PowerPADpackage, which  
eliminates bulky heatsinks. TI provides evaluation  
modules and the SWIFTdesigner software tool to aid  
in quickly achieving high-performance power supply  
designs to meet aggressive equipment development  
cycles.
