DESCRIPTION

As a member of the SWIFT™ family of dc/dc regulators,

the TPS54880 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 3.8 V; an

internally or externally set slow-start circuit to limit

inrush currents; and a power good output useful for

processor/logic reset.

The TPS54880 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.
