TPS62130RGTR 概要
A buck converter, or step-down converter, is a switching voltage regulator that efficiently reduces a higher input voltage to a lower regulated output. It is a fundamental power management IC building block, converting energy from 12V rails, batteries, or unregulated sources into the low-voltage rails required by processors, FPGAs, and sensors.
Key features include an adjustable output from 0.9V to 6V, a 2.5MHz switching frequency, and approximately 17uA quiescent current in power-save mode. Integrated synchronous rectification eliminates the external Schottky diode and improves efficiency. The device provides an enable pin, open-drain power-good output, and soft-start/tracking pin for controlled startup and power sequencing.
Technically, the TPS62130 uses DCS-Control (Direct Control with Seamless transition into Power Save Mode) topology, combining voltage-mode and current-mode control for excellent load and line regulation with seamless PWM/power-save transitions across the load range. The 2.5MHz switching frequency permits small inductors and capacitors, shrinking the total solution footprint. Overcurrent and overtemperature protection ensure robust operation.
Typical applications include standard 12V rail POL supplies, converters from single or multiple Li-ion battery stacks, solid-state drives, embedded systems, and LDO replacements where efficiency matters. High efficiency across light and heavy loads suits battery-powered portable devices, industrial control, and networking equipment.
Design tip: place input and output capacitors close to the pins to minimize parasitic inductance, solder the exposed pad to a thermal relief pattern, and use the SS/TR pin to set the output ramp or implement voltage tracking.

主な用途
TPS62130RGTR の用途: 6 件s: 12V Rail Point-of-Load Supply, Battery-Powered Portable Devices, Solid-State Drives and Storage, Industrial Control and Automation, Automotive Infotainment and Body Electronics, Networking and Communication Equipment.
12V Rail Point-of-Load Supply
The TPS62130RGTR fits standard 12V industrial and networking rails directly thanks to its 3V-17V input range, converting down to 0.9V-6V adjustable outputs at up to 3A. In a typical POL stage, a 2.2uH inductor and small ceramic capacitors are sufficient at 2.5MHz switching, yielding a compact solution. Synchronous rectification keeps efficiency high across light and heavy loads, and the DCS-Control loop provides tight regulation.

Battery-Powered Portable Devices
With approximately 17uA quiescent current in power-save mode and seamless PWM/power-save transitions, the TPS62130RGTR preserves battery life in portable and handheld instruments. It accepts single or multiple Li-ion cell stacks up to 17V input and delivers 3A peak loads for radios, displays, and processors. The wide 0.9V-6V output range supports lithium-ion charging rails and low-voltage core supplies with high light-load efficiency.
おすすめ
Solid-State Drives and Storage
SSD controllers and NAND power planes benefit from the TPS62130RGTR's compact 3x3 mm QFN footprint, 2.5MHz operation with small external components, and power-good flag for POR supervision. The SS/TR pin sets a controlled output ramp to prevent inrush stress on storage rails, while the DCS-Control topology delivers fast transient response for bursty NAND read/write current profiles up to 3A.
おすすめ
Industrial Control and Automation
Factory automation and PLC I/O modules use the TPS62130RGTR to derive 5V, 3.3V, or custom low-voltage rails from 24V-derived or 12V intermediate buses within its 17V maximum. Overcurrent and overtemperature protection support robust 24/7 operation, and the -40C to +85C operating range covers industrial cabinets. The enable and power-good pins enable rail sequencing in multi-supply control boards.
おすすめ
Automotive Infotainment and Body Electronics
The AEC-Q100 qualified family variant TPS62130QRGTRQ1 shares the identical pinout, allowing automotive designs to reuse the same PCB as industrial versions. The converter's 3-17V input tolerates car-battery load-dump-adjacent rails with upstream protection, and its 3A capacity supplies infotainment SoC, display, and connectivity modules. Soft-start tracking coordinates startup across multiple powered domains in the vehicle ECU.
おすすめ
Networking and Communication Equipment
Routers, switches, and small-cell modules employ the TPS62130RGTR as a distributed POL converter from 12V intermediate buses. Its 2.5MHz switching frequency keeps switching noise above sensitive RF bands and enables small magnetics in dense board layouts, while power-save mode maintains efficiency at light standby traffic loads. The open-drain power-good output integrates with system monitoring for fault reporting in managed network hardware.

主な差別化要因
- Full 3A output at 2.5MHz （vs TPS62140RGTR)

- Automotive-grade pin-compatible variant exists （vs TPS62130QRGTRQ1)
設計ノート
Place the input capacitors (e.g., 10uF ceramic plus 0.1uF high-frequency bypass) as close as possible to the PVIN pins (11, 12) and GND. Keep the SW node (pins 2, 3, 15) loop area minimal with the inductor. Solder the exposed thermal pad to a ground-plane thermal relief pattern; the pad is the primary thermal and power-ground path for the 3A load current.
For 12V-to-3.3V at 3A, select an inductor with a saturation current above the peak switch current limit (approximately 4A class) and low DCR to preserve efficiency. Use X7R/X5R ceramics with adequate DC bias derating on both input and output. The SS/TR capacitor sets the output ramp rate - size it per the datasheet formula for the desired startup time.
Do not exceed 17V on PVIN/AVIN; upstream transients on industrial 12V or automotive rails require TVS protection. When substituting family members, note the current rating difference (TPS62140 is 2A, TPS62150 is 1A) - drop-in does not mean performance-equivalent. Respect the -40C to +85C ambient range; power dissipation in the QFN limits junction temperature margin at full 3A load.
