Networking Equipment
In networking switches and routers, the TPSM82816 powers high-performance ASICs and PHYs. Its 2.7V to 6V input range accommodates 3.3V and 5V intermediate buses, while the 6A output handles high-current cores. The small MicroSiP™ package saves PCB area, and the optional frequency synchronization reduces electromagnetic interference, which is critical in dense, high-speed systems. Efficiency above 90% minimizes thermal stress in enclosed equipment.
Recommended
Industrial Automation
The TPSM82816 is suitable for industrial control systems, PLCs, and motor drives, providing a regulated supply for microcontrollers, sensors, and communication interfaces. Its wide input range handles unregulated 5V buses, and the adjustable soft-start prevents inrush current during power-up. The module's robust thermal performance and integrated inductor ensure reliable operation in harsh environments with limited airflow.
Recommended
Automotive Electronics
For automotive infotainment and ADAS systems, the TPSM82816 provides a compact power solution for processors and sensors. Its input range covers 5V and 3.3V rails, and the high efficiency reduces heat in cabin-mounted electronics. The optional frequency synchronization helps manage EMI in vehicles, and the integrated inductor simplifies design for space-constrained modules. Note: verify AEC-Q100 qualification for automotive use.
Recommended
Data Center Servers
In server and storage systems, the TPSM82816 powers CPU, memory, and I/O rails. Its 6A output and high efficiency reduce power losses, while the small package allows high-density board layouts. The module supports frequency synchronization to spread switching noise, which is beneficial in large systems with many converters. The integrated inductor simplifies BOM and improves reliability.
Recommended
Portable Devices
The TPSM82816 can be used in battery-powered portable devices where efficiency and size are critical. Its 2.7V minimum input allows operation from a single-cell Li-ion battery (3.0-4.2V), and the high efficiency extends battery life. The integrated inductor reduces footprint, and the adjustable output voltage supports various load requirements. The module's low quiescent current in light-load conditions further enhances battery performance.

Key Differentiators
- Wide input voltage range (2.7V to 6V) (vs LTM4626)
- Programmable switching frequency up to 4MHz (vs LTM4626)
- Integrated inductor in compact MicroSiP™ package (vs Discrete buck converters)
Design Notes
Place input and output capacitors as close to the module pins as possible to minimize parasitic inductance. Use a 10µF ceramic capacitor for input and a 22µF ceramic capacitor for output, as recommended in the datasheet. Ensure a solid ground plane beneath the module for thermal and electrical performance.
The TPSM82816 dissipates heat through the package and PCB. For high-current operation, provide adequate copper area and thermal vias to keep the junction temperature below 125°C. The MagPack™ package offers improved thermal performance compared to the MicroSiP™ package.
Do not exceed the absolute maximum input voltage of 6V. Ensure the feedback resistor divider uses 1% tolerance resistors for accurate output voltage. The soft-start capacitor value controls startup time; too small a value may cause inrush current, while too large delays power-up.
