•
Qualified for Automotive Applications  
Wide Input Voltage Range: 5.5 V to 36 V  
As a member of the SWIFT™ family of dc/dc  
regulators, the TPS5430 is a high-output-current  
pulse-width modulation (PWM) converter that  
Up to 3-A Continuous (4-A Peak) Output  
Current  
integrates  
MOSFET. Included on the substrate with the listed  
features are high-performance voltage error  
a
low-resistance high-side N-channel  
•
•
•
•
•
•
High Efficiency up to 95% Enabled by 110-mΩ  
Integrated MOSFET Switch  
a
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.  
Wide Output Voltage Range: Adjustable Down  
to 1.22 V With 1.5% Initial Accuracy  
Internal Compensation Minimizes External  
Parts Count  
Fixed 500-kHz Switching Frequency for Small  
Filter Size  
Improved Line Regulation and Transient  
Response by Input Voltage Feed Forward  
System Protected by Overcurrent Limiting,  
Overvoltage Protection, and Thermal  
Shutdown

–40°C to 125°C Operating Junction  
Temperature Range  
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.
