Typical Applications
TPS62090 is suitable for 6 applications: FPGA/Processor Point-of-Load Power, Battery-Powered Portable Devices, Automotive Infotainment and Clusters, Industrial Automation Control Boards, Wireless Communication Modules, Test and Measurement Instruments.
FPGA/Processor Point-of-Load Power
The TPS62090 fits POL conversion for FPGA, DSP, and processor core rails because its 3 A continuous output covers typical core currents while the DCS-Control topology delivers fast load-transient response during burst activity. Operating at 2.8 MHz keeps the inductor small (typically 1-2.2 uH), and the 3x3 mm VQFN-16 fits directly beneath or beside the load. The power-good output enables rail sequencing, and the soft-start pin supports voltage tracking in multi-rail processors.
Recommended
Battery-Powered Portable Devices
The TPS62090 is optimized for battery-powered applications: up to 97% efficiency extends battery runtime, and Power Save Mode reduces quiescent current to typically 20 uA at light load, critical for standby battery life. The 2.5 V input floor supports single Li-Ion cells (3.0-4.2 V) and the 6 V maximum covers USB 5 V rails. The 2.8 MHz switching frequency keeps passive components small, and the 3x3 mm package suits smartphone, tablet, and wearable form factors.
Recommended
Automotive Infotainment and Clusters
The AEC-Q100-qualified variant TPS62090QRGTRQ1 makes this converter suitable for automotive displays, infotainment SoCs, and camera modules powered from 5 V or 3.3 V rails. The 2.5-6 V input tolerates cold-crank transients on regulated intermediate rails, while DCS-Control maintains accurate output voltage during sudden load changes from display backlight or processor wake events. Pin-compatible drop-in means the standard TPS62090 can be used in non-qualified industrial variants of the same board.
Recommended
Industrial Automation Control Boards
In industrial PLC I/O modules and motor-control boards, the TPS62090 generates 3.3 V or 1.8 V logic rails from a 5 V intermediate bus with high efficiency, reducing cabinet thermal load. Its 3 A rating powers microcontrollers, transceivers, and sensor front-ends, while the power-good pin allows the host to supervise rail health. The small solution size supports dense modular I/O cards, and ceramic-output designs meet EMC requirements with proper layout.
Recommended
Wireless Communication Modules
RF modules and cellular IoT modems exhibit high peak-to-average current draw; the TPS62090 handles 3 A peaks while DCS-Control's fast transient response limits rail droop during transmit bursts. The 2.8 MHz switching frequency places switching noise far from common IF bands, easing filtering. At idle, 20 uA power-save quiescent current preserves battery life in always-on nodes. The power-good pin can gate module enable to prevent brownout during registration bursts.
Recommended
Test and Measurement Instruments
Handheld meters and portable instruments benefit from the TPS62090's 97% peak efficiency and compact footprint when generating local 1.8 V/2.5 V rails from Li-Ion or USB power. The adjustable output (0.8 V to VIN) lets one design cover multiple SKUs, and the soft-start pin enables sequenced bring-up of analog and digital sections. Excellent output-voltage accuracy supports precision front-end circuitry powered from the same rail.

Key Differentiators
- 6 V maximum input rating (vs TLV62090RGTR)
- Automotive-qualified drop-in option (vs TPS62090QRGTRQ1)
- DCS-Control with 20 uA power save (vs TPS62130RGTR)
Design Notes
Place the input capacitor (10 uF ceramic) as close as possible to PVIN/AVIN and PGND, and keep the SW-to-inductor-to-output-capacitor loop short and wide. Connect the exposed pad directly to a solid PGND plane with multiple vias for thermal dissipation. Keep the VFB feedback trace away from the SW node and inductor to prevent noise coupling into the regulation loop.
The DCS-Control topology requires a minimum output capacitance for stability - do not reduce below the datasheet recommendation. When using the adjustable version, note the datasheet guidance that output voltage accuracy can be improved by programming the output slightly lower (e.g., target 3.3 V programmed as 3.3 V - 0.8%, tightening the window from -1.4%/+3% to -2.2%/+2.2%). Do not exceed 6 V input; for 5 V-rail-only designs the 5.5 V-limited pin-compatible parts are fine.
For sequencing multi-rail processors, use the SS/TR pin for output voltage tracking and the enable plus PGOOD pins for cascade sequencing. Select the inductor per the datasheet table for your output voltage (typically 1-2.2 uH at 2.8 MHz); undersized inductance increases ripple current and may trigger current limit prematurely at 3 A loads.
Compliance Information
RoHS compliant per distributor listings. AEC-Q100 qualification applies only to the TPS62090QRGTRQ1 variant.
