Typical Applications
TPSM82822A is suitable for 6 applications: FPGA and Processor Core Power, Optical Modules and Network Transceivers, Solid-State Drives and Storage, Industrial Automation and Control, Portable and Battery-Powered Devices, Automotive Infotainment and Clusters.
FPGA and Processor Core Power
The TPSM82822A fits FPGA, DSP, and ASIC power rails because its 0.6 V to 4 V adjustable output covers modern low-voltage core requirements while delivering 2 A continuous current. Forced PWM operation at 2.2 MHz keeps switching ripple low and the EMI spectrum predictable, important for noise-sensitive digital cores. Placed as a point-of-load regulator next to the processor, the integrated inductor reduces the solution to a few mm2, and the power-good output supports sequencing supervision in multi-rail processor systems.
Recommended
Optical Modules and Network Transceivers
Optical module power stages demand tiny footprints, low profile, and clean rails, all strengths of the TPSM82822A. The 2 x 2.5 x 1.1 mm MicroSiP with integrated inductor fits within the strict height envelope of SFP-class transceivers, while the 2.4 V to 5.5 V input accepts 3.3 V module supplies directly. Forced PWM provides constant-frequency, low-ripple output for sensitive laser driver and TIA circuits, and efficiency up to 95% limits heat inside the sealed module enclosure.
Recommended
Solid-State Drives and Storage
SSD controllers require compact, efficient point-of-load conversion from a 5 V or 3.3 V rail. The TPSM82822A's 5.5 V maximum input and 2 A output cover typical SSD controller and NAND rail needs, while the integrated inductor minimizes component height for slim drive form factors. Forced PWM mode maintains low output ripple under bursty NAND read/write load transients, and the power-good flag lets the storage controller verify rail integrity during power-up before initializing firmware.
Recommended
Industrial Automation and Control
In industrial control boards, the TPSM82822A powers MCUs, sensors, and interface ICs from 5 V backplane rails. The forced PWM mode gives a deterministic EMI signature that simplifies compliance with industrial EMC requirements, and operation at 2.2 MHz keeps switching noise above sensitive analog signal bands. The module's integrated inductor withstands vibration better than wire-wound discretes, improving reliability in factory automation and motor control environments with 2 A logic rails.
Recommended
Portable and Battery-Powered Devices
The 2.4 V minimum input accepts single-cell lithium-ion supplies near end of discharge, and efficiency up to 95% at typical loads extends battery runtime in handheld instruments and wearables. The 1.1 mm profile and 5 mm2 footprint suit space-constrained portable PCBs. Forced PWM trade-off: unlike power-saving mode variants, the TPSM82822A draws constant-frequency switching current at light load, so choose the TPSM82822 sibling instead if light-load efficiency dominates the use case.
Recommended
Automotive Infotainment and Clusters
Automotive display and infotainment subsystems use 5 V intermediate rails feeding multiple point-of-load converters. The TPSM82822A's 2 A output, power-good flag, and small footprint suit camera-module, cluster, and connectivity-module rails on TI Sitara/Jacinto designs. Forced PWM keeps output ripple low for adjacent high-speed serializers, and TI offers related Q1-qualified power modules in the family roadmap - verify automotive qualification requirements per project before final selection.

Key Differentiators
- Forced PWM constant-frequency operation (vs TPSM82822SILR)
- Right-sized 2 A rating (vs TPSM82823)
- Smaller footprint than discrete-inductor modules (vs TPS82085SILR)
Design Notes
Place the input ceramic capacitor within 1-2 mm of the PVIN and GND pins to minimize the high-frequency switching loop; this is the single most important layout rule for module-based bucks. Use a solid ground plane and short, wide power traces. Follow the TPSM8282x datasheet recommended layout exactly - the integrated inductor simplifies design but does not eliminate the input loop concern.
At high duty-cycle conversions (e.g., 5 V to 1.8 V at 2 A), module losses near 0.5 W require thermal relief. Add an array of thermal vias under and around the package connecting to internal ground planes, and allocate at least 1 square inch of copper for sustained full-load operation. Verify junction temperature stays within datasheet limits at worst-case ambient.
Do not confuse TPSM82822A (forced PWM) with TPSM82822 (light-load efficiency mode) when ordering - the suffix letter changes operating mode and light-load behavior. Use ceramic capacitors with the exact capacitance and ESR ranges specified in the datasheet; excessive output capacitance or very low-ESR combinations can affect loop stability of the internal compensation.
