DESCRIPTION
As a member of the SWIFT family 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) 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.
