Frequently Asked Questions
What are the output voltage and current capabilities of the TPSM5D1806RDBR for FPGA power rail design?
The TPSM5D1806RDBR provides two independent output rails each adjustable from 0.5 V to 5.5 V, each rated at 6 A continuous output current. This makes it well-suited for powering FPGA core voltages at 0.85 V or 1.0 V while simultaneously supplying I/O banks at 1.8 V or 3.3 V, all from a single 12 V input bus without requiring separate discrete regulators.
How does the integrated module design of TPSM5D1806RDBR reduce PCB design complexity compared to discrete solutions?
As a fully integrated power module, the TPSM5D1806RDBR embeds the switching inductors, control IC, and passive components within a single 51-pin package. This eliminates the need for external inductors and reduces the PCB area required versus a discrete dual-channel buck design. Engineers can achieve 12 A total load capacity (6 A per channel) with minimal external components, speeding up layout and reducing EMI optimization effort.
What input voltage range does TPSM5D1806RDBR support, and which system bus architectures are compatible?
The TPSM5D1806RDBR operates from 4.5 V to 15 V input, with a nominal input of 12 V. This range is compatible with standard 5 V, 9 V, and 12 V distribution buses used in telecom equipment, industrial controllers, and server infrastructure. The wide input tolerance also accommodates voltage droop on 12 V rails common in loaded backplane environments, ensuring reliable regulation down to 4.5 V.
When was the TPSM5D1806RDBR introduced, and what is its expected product lifetime for long-lifecycle industrial designs?
Texas Instruments introduced the TPSM5D1806RDBR in December 2020 with a YTEOL (years to end-of-life) rating of 15 years, indicating long-term production commitment through approximately 2035. This extended lifecycle assurance is important for industrial and telecom equipment manufacturers who require supply chain continuity for 10+ year product support obligations, reducing redesign risk.
