Key Features
- Fully integrated power module with embedded inductor, controller, and FETs enabling single-component 4 A point-of-load regulation
- 0.8 V to 3.6 V adjustable output covering FPGA core, DDR memory, and digital logic rails from a single 2.95 V to 6 V input
- Voltage-mode control in a 39-pin B1QFN module minimizing PCB design effort and reducing time-to-market for dense power trees
Applications
The TPS84410RKGR is designed as a drop-in point-of-load power module for FPGA development boards, network processors, and SoC-based industrial controllers where the 4 A output supplies core logic or DDR memory rails down to 0.8 V. Integrating the inductor and power stage in the B1QFN module eliminates magnetic component selection and layout iterations, shrinking the power supply design cycle from weeks to days. It also fits communications infrastructure line cards and test instrumentation that must regulate sub-1 V rails from a 3.3 V or 5 V intermediate bus with minimal PCB space allocation.

Frequently Asked Questions
How does the TPS84410RKGR's integrated inductor simplify PCB design compared to a discrete step-down controller?
In a discrete step-down design, the engineer selects an inductor rated for at least 4 A DC current, optimizes the switching frequency vs. core loss tradeoff, and must keep the inductor physically close to the switching node to minimize radiated EMI, often consuming 100 mm² to 200 mm² of board area including the power loop. TPS84410RKGR embeds the inductor within the 39-pin B1QFN package, reducing the total footprint to approximately 30 mm² and eliminating all magnetic component selection, pre-layout simulation, and post-layout EMI iteration. The result is a verified, application-optimized power stage that meets the 4 A rating out of the box.
Which FPGA core supply voltages can TPS84410RKGR regulate, and how does it handle the tight load transient requirements?
The TPS84410RKGR's adjustable output range of 0.8 V to 3.6 V covers FPGA core voltages such as 1.0 V for Xilinx 7-series cores, 0.85 V for UltraScale+, and 1.2 V for Intel Cyclone V I/O banks, as well as DDR4 VDD at 1.2 V and DDR3 at 1.5 V. Its voltage-mode control loop and internal compensation are tuned for the 4 A current rating, enabling fast response to load steps of several amps that occur during FPGA reconfiguration or bus activity bursts, keeping the output within ±3 % of the setpoint with modest output capacitance.
What input voltage range does TPS84410RKGR support, and how does that map to common intermediate bus architectures in telecom line cards?
The TPS84410RKGR accepts inputs from 2.95 V to 6 V with a nominal 3.3 V operating point, which aligns directly with the 3.3 V and 5 V intermediate bus voltages common in ATCA, AdvancedTCA, and compact PCI telecom line cards. The 6 V upper limit provides margin above a 5 V bus for transients and long cable drops, while the 2.95 V lower bound allows operation from a 3.3 V rail that has sagged to 90 % of its nominal value during heavy load conditions. This input flexibility removes the need for a pre-regulator stage when powering sub-1 V ASIC cores in shelf architectures that distribute both 3.3 V and 5 V.
