DESCRIPTION
As a member of the SWIFT™ family of dc/dc regulators,
the TPS54973 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 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
in-rush currents; and a power good output useful for
processor/logic reset, fault signaling, and supply
sequencing.
For reliable power up in output precharge applications,
the TPS54973 is designed to only source current during
startup.
The TPS54973 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.
