Typical Applications
TPSM82816SIER is suitable for 6 applications: FPGA and Processor Point-of-Load Power, Telecommunication Equipment, Test and Measurement Instruments, Medical and Diagnostic Equipment, Industrial Automation and Robotics, Compact and Portable Instrumentation.
FPGA and Processor Point-of-Load Power
The TPSM82816's 6A capability and 0.6-5.5V adjustable output directly cover FPGA core and I/O rail requirements, while its fast peak current-mode transient response handles sharp load steps typical of processor clocks. Integrated shielding reduces switching noise near sensitive digital circuits, and SS/TRACK sequencing simplifies multi-rail power-up. Placing the module within millimeters of the load pin minimizes parasitic drop; one layout also supports 1A-4A family siblings for derivative boards.
Recommended
Telecommunication Equipment
TI cites telecommunication as a primary market for the TPSM8281x family, where dense line cards need compact, efficient 6A point-of-load conversion from 5V distribution rails. The 2.7-6V input range and over 90% peak efficiency reduce thermal load in sealed enclosures. Frequency synchronization lets hundreds of modules switch in phase, avoiding audible beat tones and easing EMC qualification across the card.
Recommended
Test and Measurement Instruments
Bench instruments and modular measurement systems require clean, low-EMI rails for ADCs and clock circuitry; the TPSM82816's shielded inductor and synchronized switching minimize spurious noise pickup. Its pin-to-pin family lets a common carrier PCB populate 1A to 6A modules for different instrument tiers, cutting qualification effort. The adjustable 0.6-5.5V output covers analog, digital, and interface supplies from one BOM position.
Recommended
Medical and Diagnostic Equipment
TI explicitly lists medical applications for the TPSM8281x family. Diagnostic platforms use the 6A module for processor and memory rails where power density is limited, and the integrated protection set (overcurrent, overvoltage, thermal shutdown) supports fail-safe operation. The complete-module construction reduces component count, simplifying design verification. For patient-adjacent systems, pair with isolated upstream supplies and verify IEC 60601 compliance at the system level.
Recommended
Industrial Automation and Robotics
Industrial controllers drive relays, sensors, and communications from 5V buses; the TPSM82816's 2.7-6V input and 6A output deliver robust point-of-load power for PLC I/O and edge compute. Fixed-frequency current-mode control gives predictable behavior across line and load, and wide protection coverage handles fault conditions common on factory floors. Single-layout scalability to 1A-4A variants supports product families with mixed power budgets.
Recommended
Compact and Portable Instrumentation
The MicroSiP package with integrated inductor achieves high power density for handheld and board-space-constrained designs. Eliminating external magnetics cuts solution height and BOM risk, while over 90% peak efficiency extends battery runtime in portable testers and field instruments. Adjustable soft-start limits inrush from battery sources, and the family's pin-to-pin compatibility allows a 6A engineering build to be cost-reduced to lower-current variants in production.

Key Differentiators
- Highest current tier in pin-compatible family (vs TPSM82814SIER)
- Frequency synchronization standard (vs TPSM82810SIER)
- Trade-off: higher cost than lower-current tiers (vs TPSM82813SIER)
Design Notes
Place input ceramic capacitance (per datasheet recommendation) directly at the PVIN/PGND pins; even with an integrated inductor, high di/dt loops remain at the module pins. Use solid ground planes under the MicroSiP footprint to minimize loop area and support thermal dissipation through the package. Keep the VFB divider traces short and away from the switch node to preserve regulation accuracy.
Although peak efficiency exceeds 90% for 5V-to-1.8V conversion, at 6A continuous load, losses of roughly 0.5-1W occur depending on VOUT. Verify junction temperature against the datasheet theta-JA with your PCB copper area; larger ground pours reduce thermal resistance. Thermal shutdown protects the device, but repeated trips indicate inadequate copper or airflow.
Do not exceed the 6V absolute maximum input - 5V rails with transients can approach the limit. When paralleling or cascading modules, use frequency synchronization to avoid beat frequencies. When using SS/TRACK for sequencing, ensure the tracked rail matches the ratio expected by the target FPGA/processor, and re-verify output stability with the actual output capacitance selection.
