Typical Applications
TPSM82816 is suitable for 6 applications: FPGA Point-of-Load Power, Telecommunication Equipment, Test and Measurement Instrumentation, Medical and Diagnostic Equipment, Processor Core Rail in Servers and Switches, Industrial Automation and Control.
FPGA Point-of-Load Power
The TPSM82816 is well suited to FPGA core and auxiliary rails because its 0.6V to 5.5V adjustable output reaches low core voltages and its 6A capability covers mid-density FPGAs. Fixed-frequency peak current-mode control delivers fast transient response during logic switching bursts. The SS/TRACK pin enables core-before-IO sequencing, and the integrated shielded inductor keeps the small MicroSiP footprint clean for placement near the FPGA power pins.
Recommended
Telecommunication Equipment
In telecom line cards and baseband boards, the TPSM82816 converts a 5V intermediate bus down to processor and memory rails at up to 6A. The datasheet explicitly cites telecommunication applications with high power density and ease of use. Optional frequency synchronization lets multiple modules switch in phase or spread spectrum, reducing audible beat frequencies and EMI, while overcurrent and thermal shutdown protect dense multi-rail boards.
Recommended
Test and Measurement Instrumentation
Test and measurement boards demand compact, low-noise point-of-load supplies for ADCs, FPGAs, and clock circuitry. The TPSM82816's shielded integrated inductor minimizes radiated EMI near sensitive analog front ends, and its programmable switching frequency lets designers avoid sensitive spectral bands. The wide 2.7V to 6V input tolerates bench supply variation, and adjustable soft-start prevents inrush issues during instrument power-up.
Recommended
Medical and Diagnostic Equipment
The TI datasheet lists medical applications among the primary uses of the TPSM8281x family. Patient-adjacent diagnostic equipment benefits from the module's high integration, which reduces component count and associated failure points, and its comprehensive protection features including overcurrent, overvoltage, and thermal shutdown. The small MicroSiP footprint supports portable and handheld medical devices where board space and weight are constrained.
Recommended
Processor Core Rail in Servers and Switches
Networking switches and server boards use the TPSM82816 for 6A-class point-of-load rails feeding ASIC cores, memories, and PHYs. The high power density of the integrated-inductor module allows placement directly at the load, reducing PCB losses and improving transient behavior at the load pins. Output voltage tracking supports the strict power-up ordering required by modern network processors and switch silicon.
Recommended
Industrial Automation and Control
Industrial controllers, I/O modules, and motor-drive logic boards need robust 3.3V and lower rails derived from 5V buses. The TPSM82816 provides 6A with thermal shutdown and overcurrent protection suited to electrically noisy factory environments. Its fixed-frequency operation avoids variable-frequency EMI signatures that can interfere with analog sensing, and the compact MicroSiP package fits high-density PLC and drive control cards.

Key Differentiators
- Highest current in the pin-to-pin TPSM8281x family (vs TPSM82813)
- Optional frequency synchronization and tracking (vs TPSM82822A)
- Integrated shielded inductor in MicroSiP package (vs Discrete buck solutions such as TPS54620)
Design Notes
Place input ceramic capacitance (typically 10uF or more, verify per datasheet recommendation table) directly at the PVIN/PGND pins with minimal loop area. Although the inductor is integrated, the input loop still carries pulsed current and dominates conducted EMI. Use a solid ground plane under the module and connect AGND and PGND at a single star point per the TI datasheet layout guidelines.
Use the SS/TRACK pin for multi-rail sequencing in FPGA or processor systems. An external RC on SS/TRACK sets a monotonic soft-start that prevents current-limited startups with large output capacitance. The RT/SYNC pin allows locking to a system clock or shifting frequency; choose the frequency to balance efficiency versus solution size since lower frequency improves efficiency at light load.
Do not substitute other MicroSiP modules (e.g., TPS82085) without verifying pinout - the MicroSiP outline is shared across families but pin functions differ. Ensure the feedback divider and output capacitor selection match the datasheet stability requirements; excessive output capacitance without soft-start adjustment can trip hiccup at startup. Confirm worst-case thermal with the maximum VIN-VOUT differential at 6A load.
Compliance Information
Compliance data not present in the verified web data. Check the TI product page quality section for RoHS and REACH status of the specific orderable part number (e.g., TPSM82816SIER).
