DC Switching Voltage Regulators

TPS56628DDA Description

The TPS56628DDA from Texas Instruments is a high-efficiency, 6A synchronous buck converter designed for demanding power management applications. This adjustable output regulator operates over a wide 4.5V to 18V input range, delivering a tightly regulated output voltage from 0.765V to 5.5V. With a 650kHz switching frequency, it balances efficiency and component size, making it suitable for space-constrained designs. Packaged in an 8-pin SOP (HSOP-8) with surface-mount compatibility, it integrates a synchronous rectifier for improved thermal performance and efficiency. Compliant with ROHS3 and REACH, it meets stringent environmental standards while offering active product status for long-term availability.

TPS56628DDA Features

• High Efficiency: Synchronous rectification reduces power loss, achieving peak efficiency for 6A output currents.
• Wide Input Range: Supports 4.5V–18V, ideal for industrial, automotive, and telecom systems.
• Adjustable Output: 0.765V–5.5V flexibility for diverse load requirements.
• Compact Design: 650kHz fixed frequency minimizes external inductor size.
• Robust Protection: Built-in thermal shutdown, overcurrent, and undervoltage lockout (UVLO).
• Low Noise: Optimized switching reduces EMI, critical for sensitive applications.
• Industry Compliance: ROHS3, REACH, and ECCN EAR99 certified.

TPS56628DDA Applications

• Point-of-Load (POL) Regulation: Precision voltage delivery for FPGAs, ASICs, and processors.
• Industrial Automation: Powering sensors, PLCs, and motor drives in harsh environments.
• Telecom Infrastructure: Efficient DC/DC conversion in base stations and networking equipment.
• Consumer Electronics: Compact power solutions for set-top boxes, displays, and IoT devices.
• Automotive Systems: Reliable performance in infotainment and ADAS modules (non-safety-critical).

Conclusion of TPS56628DDA

The TPS56628DDA stands out for its high current capability, wide input range, and compact footprint, making it a superior choice over non-synchronous or lower-current alternatives. Its synchronous topology and adjustable output cater to modern power designs requiring efficiency and flexibility. Whether for industrial, automotive, or telecom applications, this regulator delivers reliable, high-performance power conversion with minimal external components. Texas Instruments’ reputation for quality ensures this device is a dependable solution for engineers prioritizing efficiency and space savings.
