3-A WIDE-INPUT-RANGE STEP-DOWN SWIFT™ CONVERTER

FEATURES

DESCRIPTION

•

Wide Input Voltage Range: 5.5 V to 36 V

•

Up to 3-A Continuous (4-A Peak) Output

Current

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

regulators, the TPS5430 is a high-output-current

pulse-width modulation (PWM) converter that

•

High Efficiency up to 95% Enabled by 110-mΩ

Integrated MOSFET Switch

integrates

MOSFET. Included on the substrate with the listed

features are high-performance voltage error

low-resistance high-side N-channel

Wide Output Voltage Range: Adjustable Down

to 1.22 V With 1.5% Initial Accuracy

amplifier that provides tight voltage regulation

accuracy under transient conditions, an undervoltage

lockout (UVLO) circuit to prevent start-up until the

input voltage reaches 5.5 V, an internally set

slow-start circuit to limit inrush currents, and a voltage

feed-forward circuit to improve the transient

response. Using the enable (ENA) pin, shutdown

supply current is reduced to 18 µA typically. Other

features include an active-high enable, overcurrent

limiting, overvoltage protection (OVP) and thermal

shutdown. To reduce design complexity and external

component count, the TPS5430 feedback loop is

internally compensated. The TPS5430 regulates a

wide variety of power sources including 24-V buses.

Temperature Range

Available in Small Thermally Enhanced 8-Pin

SOIC PowerPAD™ Package

The TPS5430 device is available in a thermally

enhanced, easy-to-use 8-pin SOIC PowerPAD™

package. 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.
