Typical Applications
TPSM5601R5 is suitable for 6 applications: 24-V and 48-V Industrial Bus Power Supplies, Factory Automation and PLC I/O Modules, Test and Measurement Point-of-Load Rails, Distributed Power Systems, Motor Drive and Motion Control Logic Supplies, Networking and Communications Infrastructure.
24-V and 48-V Industrial Bus Power Supplies
The TPSM5601R5's 4.2-V to 60-V input range directly accommodates 24-V and 48-V industrial distribution rails with transient headroom up to 60 V. Its 1-V to 6-V adjustable output at 1.5 A covers common logic and analog rails (3.3 V, 5 V) derived from the bus. Placed as the final regulation stage after bulk conversion, the integrated shielded inductor and internal compensation produce a compact, low-EMI solution requiring only about four external components, reducing BOM and layout risk in dense industrial control cabinets.
Recommended
Factory Automation and PLC I/O Modules
PLC digital and analog I/O cards need a compact, reliable point-of-load from a 24-V backplane. The TPSM5601R5's -40C to +125C junction range and integrated magnetics withstand cabinet temperature swings without external inductor derating concerns. The 400-kHz fixed switching simplifies input filter design for EMI compliance, and the EN pin supports controlled power-up sequencing of card rails. All perimeter pins and a single thermal pad make automated optical inspection and rework straightforward in high-volume PLC manufacturing.
Recommended
Test and Measurement Point-of-Load Rails
Instrumentation boards frequently combine a high-voltage input stage with sensitive analog loads. The TPSM5601R5 generates a clean 1-V to 6-V rail from a 60-V capable input, letting designers derive logic and analog supplies directly from wide-range auxiliary inputs. The Enhanced HotRod QFN's low EMI and integrated shielded inductor minimize switching artifacts coupling into measurement paths, and the adjustable output via one resistor divider speeds board bring-up and optioning across instrument product variants.
Recommended
Distributed Power Systems
In distributed architectures, a 48-V intermediate bus feeds multiple point-of-load converters. The TPSM5601R5 provides local regulation at each load point, with its 60-V rating absorbing bus transients. Its small 5-mm x 5.5-mm footprint and integrated magnetics fit at the point of load without dedicated magnetics area, and the fixed 400-kHz frequency keeps ripple filter components predictable. The single-resistor output adjustment lets one PCB layout serve multiple rail voltages across a product family.
Recommended
Motor Drive and Motion Control Logic Supplies
Motor drives combine high-voltage stages with 24-V or 48-V control buses from which logic supplies are derived. The TPSM5601R5 powers gate-driver bias and controller rails (3.3 V/5 V at 1.5 A) from the control bus while tolerating bus transients up to 60 V. Its integrated shielding limits switching noise that could couple into encoder and feedback circuits, and the -40C to +125C junction range suits drive enclosures with limited airflow near power stages.
Recommended
Networking and Communications Infrastructure
Telecom and networking equipment use 48-V plant power, making the TPSM5601R5's 60-V input a natural fit for board-level point-of-load conversion. The compact module delivers 3.3-V or 5-V rails for control processors and transceivers at up to 1.5 A. The 400-kHz fixed switching and integrated inductor ease compliance with conducted EMI limits, and the EN pin enables orderly sequencing with upstream hot-swap controllers during card insertion in live backplanes.

Key Differentiators
- Integrated shielded inductor and compensation (vs TPS54360QDDARQ1 (discrete buck))
- Spread-spectrum EMI variant in identical footprint (vs TPSM5601R5S)
- Extended output and temperature variants (vs TPSM5601R5H / TPSM5601R5H EXT)
Design Notes
Because the shielded inductor is integrated, all heat dissipation is concentrated in the module package. TI recommends a minimum 1-square-inch copper pour on the ground layer connected to the exposed thermal pad through an array of thermal vias. Without adequate copper, full 1.5-A operation at 60-V input and high ambient temperatures may hit the +125C junction limit. Use the datasheet thermal derating curves for your exact VIN/VOUT operating point.
Place the input ceramic capacitor as close as possible to the VIN and GND pins to minimize high-frequency loop area. Keep the feedback resistor divider traces short and away from the SW node to avoid noise pickup on the output sense line. All functional pins are on the package perimeter, simplifying routing and inspection versus BGA-style modules.
The fixed 400-kHz switching frequency produces a predictable fundamental for input filter design. If conducted EMI limits are aggressive, choose the TPSM5601R5S variant, which operates identically but adds spread-spectrum modulation to reduce peak emissions. This can remove several dB of peak energy around 400 kHz without any PCB change since the footprint is identical.
