TPS54380-Q1

SLVS836 − JUNE 2008

3-V TO 6-V INPUT, 3-A OUTPUT TRACKING SYNCHRONOUS BUCK

PWM SWITCHER WITH INTEGRATED FETs (SWIFT) FOR SEQUENCING

FEATURES

DESCRIPTION

Qualified for Automotive Applications

Power-Up/Down Tracking for Sequencing

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.

60-mΩ MOSFET Switches for High Efficiency

at 3-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 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.
