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

SWITCHER WITH INTEGRATED FETs (SWIFT)

FEATURES

DESCRIPTION

Qualified for Automotive Applications

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

TPS54311, TPS54312, TPS54313, TPS54314,

60-mΩ MOSFET Switches for High Efficiency

at 3-A Continuous Output Source or Sink

Current

0.9-V, 1.2-V, 1.5-V, 1.8-V, 2.5-V, and 3.3-V Fixed

Output Voltage Devices With 1% Initial

Accuracy

Internally Compensated for Low Parts Count

Fast Transient Response

Wide PWM Frequency: Fixed 350 kHz,

550 kHz, or Adjustable 280 kHz to 700 kHz

Load Protected by Peak Current Limit and

Thermal Shutdown

TPS54315, and TPS54316 low-input-voltage high-output

current synchronous-buck PWM converters integrate 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.

The TPS54311, TPS54312, TPS54313, TPS54314,

TPS54315, and TPS54316 devices are 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.

Integrated Solution Reduces Board Area and

Total Cost

APPLICATIONS

Low-Voltage, High-Density Systems With

Power Distributed at 5 V or 3.3 V

Point of Load Regulation for High

Performance DSPs, FPGAs, ASICs, and

Microprocessors

Broadband, Networking and Optical

Communications Infrastructure

Automotive Telematics

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.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments

semiconductor products and disclaimers thereto appears at the end of this data sheet.

PowerPAD and SWIFT are trademarks of Texas Instruments.

PRODUCTION DATA information is current as of publication date. Products

conform to specifications per the terms of Texas Instruments standard warranty.

Production processing does not necessarily include testing of all parameters.
