DESCRIPTION
As a member of the SWIFT family of dc/dc regulators,
the TPS54680 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 under-voltage-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 TPS54680 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.
