TPS5430DDAR Buck Regulator
3A Continuous Output meets 36V Wide Input Range – The Professional SWIFT™ DC-DC Converter Silicon Choice for Industrial Controller Mainboards and High-Efficiency Power Modules.
// 500kHz Fixed Frequency Built-in 110mΩ Power MOSFET SO-PowerPAD-8 Portfolio
The High-Efficiency Non-Isolated Step-Down Advantage
The TPS5430DDAR represents a premier professional SO-PowerPAD-8 packaged monolithic PWM step-down buck DC-DC converter solution engineered for space-constrained, high-throughput hardware architectures demanding absolute power conversion efficiency and wide supply rails tolerance. Built on Texas Instruments’ advanced proprietary SWIFT™ technology framework operating at a deterministic 500 kHz frequency node, this module processes high-current load lines up to 3A continuous flawlessly without excessive thermal runaway hazards or systemic performance lagging. Housed in an industry-standard 8-pin SOIC format with an integrated exposed thermal pad underneath, it secures pure, deterministic power routing loops and completely cuts off board layout overhead bottlenecks.
- Wide operating DC input voltage range from 5.5V up to 36V matching industrial bus standards safely
- Integrated high-side N-channel power MOSFET (110 mΩ typical Rdson) maximizing efficiency cleanly
- Comprehensive embedded security protection loops including overcurrent limit and thermal shutdown smoothly
Key Performance Advantages
3A Continuous Current
Supports high peak currents up to 4A, continuously driving heavy load currents safely for complex industrial mainboards and wireless modems cleanly.
95% Power Efficiency
Optimizes active power conversion parameters via low-resistance switching nodes, suppressing systemic thermal generation profiles safely.
SO-PowerPAD-8 Package
Combines standard small-outline packaging layouts with a bottom thermal metal slug, maximizing heat conduction tracks smoothly.
