High-Efficiency Buck Regulator for Industrial Power Systems & Embedded Computing
The TPS5430DDAR is a high-performance synchronous buck converter delivering 3A continuous output current with 95% peak efficiency. Designed for industrial automation, networking equipment, and portable electronics, this regulator features a 5.5V-36V wide input range and ±1% output voltage accuracy for precision power management. Its integrated 110mΩ N-channel MOSFET reduces heat dissipation, while adaptive PWM/PFM modes optimize efficiency across load conditions (0.1mA to 3A).
110mΩ MOSFET Delivers 3A Continuous Output with Multi-Mode Protection
Key Benefits for Engineers:
✔ Industrial-Grade Reliability: Over-temperature/short-circuit/UVLO protection
✔ Multi-Mode Operation: Auto-switches between PWM, PFM, and low-power modes
✔ Space-Saving Design: 8-SOIC package (4.9mm × 3.9mm) for compact PCBs
✔ Wide Compatibility: Ideal for 12V/24V rail systems in routers, PLCs, and motor drives
