FEATURES

DESCRIPTION

(1)

Qualification in Accordance With AEC-Q100

Qualified for Automotive Applications

Customer-Specific Configuration Control Can

Be Supported Along With Major-Change

Approval

As members of the SWIFT family of dc/dc regulators,

the TPS54310 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 provides high performance

under transient conditions, an undervoltage-lockout

circuit to prevent start up until the input voltage reaches

3 V, an internally and 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.

60-mΩ MOSFET Switches for High Efficiency

at 3-A Continuous Output Source or Sink

Current

0.9-V to 3.3-V Adjustable Output Voltage With

1% Accuracy

Externally Compensated for Design Flexibility

Fast Transient Response

Wide PWM Frequency: Fixed 350 kHz,

550 kHz, or Adjustable 280 kHz to 700 kHz

The TPS54310 device is available in a thermally

enhanced 20-pin TSSOP (PWP) PowerPAD

package, which eliminates bulky heatsinks. Texas

Instruments 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.

Load Protected by Peak Current Limit and

Thermal Shutdown

Integrated Solution Reduces Board Area and

Total Cost
