DESCRIPTION

(1)

Qualification Pedigree

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.

Power Up/Down Tracking For Sequencing

30-mΩ, 12-A Peak MOSFET Switches for High

Efficiency at 6-A Continuous Output Source

or Sink Current

Wide PWM Frequency:

Fixed 350 kHz or Adjustable 280 kHz to

700 kHz

Power Good and Enable

Load Protected by Peak Current Limit and

Thermal Shutdown

Integrated Solution Reduces Board Area and

Component Count

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.

Componentqualification in accordance with JEDEC and industry

standards to ensure reliable operation over an extended

temperature range. This includes, but is not limited to, Highly

Accelerated Stress Test (HAST) or biased 85/85, temperature

cycle, autoclave or unbiased HAST, electromigration, bond

intermetalliclife, and mold compound life. Such qualification testing

should not be viewed as justifying use of this component beyond

specified performance and environmental limits.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during

storage or handling to prevent electrostatic damage to the MOS gates.
