TPS62130ARGTT - 3-17V 3A Step-Down Converter | Texas Instruments
MPN: TPS62130ARGTT ✓ Hoạt độngTPS62130ARGTT Tóm tắt
A DC-DC buck converter is a switch-mode voltage regulator that steps a higher DC input voltage down to a lower DC output voltage by rapidly switching an inductor/capacitor network. It belongs to the broader family of voltage regulators (linear regulators, switching regulators) inside power management ICs for semiconductors. Switching regulators like the TPS62130 family are preferred over LDOs when high efficiency, wide input range, or high load current make linear regulation impractical due to power dissipation.
Key features include 3 V to 17 V input voltage range, up to 3 A output current, adjustable output from 0.9 V to 6 V, pin-selectable nominal / +5% output voltage, programmable soft-start and tracking, power-good output, output discharge, and 17 uA quiescent current. The 2.5 MHz typical switching frequency permits use of chip inductors under 1 uH, enabling designs smaller than 25 mm² total solution area. The VQFN-16 (RGT) package provides a thermal resistance of approximately 38 C/W on a 4-layer JEDEC standard test board.
The TPS62130A uses TI's DCS-Control topology, which combines the fast transient response of hysteresis control with the DC accuracy of a voltage-mode loop. This gives the converter stable operation with ceramic output capacitors and pseudo-fixed-frequency switching under continuous load, while still entering power-saving mode at light load for high efficiency across the full load range.
Typical applications include 12 V distributed bus POL converters for industrial PCs, USB Type-C / PD powered device rails, portable equipment battery-powered systems, FPGA/CPLD core and I/O supplies, and compact solid-state drives. A 12 V to 3.3 V conversion at 2 A is a common use case for this part.
When designing with this device, choose a low-DCR power inductor with saturation current at least 30% above the maximum DC load; insufficient headroom causes output ripple and possible sub-harmonic instability in DCS-Control. Place input ceramic capacitors as close as possible to PVIN and PGND to minimize switching noise on the input rail.

Ứng dụng tiêu biểu
TPS62130ARGTT phù hợp cho 6 Áp dụngs: 12 V Distributed-Bus POL Converter, USB Type-C Powered Device Rails, Portable Battery-Powered Systems, FPGA / CPLD Core and I/O Supplies, Solid-State Drive (SSD) Power Tree, Industrial Sensor and PLC Modules.
12 V Distributed-Bus POL Converter
The TPS62130ARGTT's 17 V maximum input makes it well suited to step down a 12 V industrial or server bus to 3.3 V or 5 V rails for downstream ICs. The 2.5 MHz switching enables small ceramic output capacitors and a chip inductor under 1 uH for compact POL footprints under 25 mm squared. The 90% plus typical efficiency at 12 V to 3.3 V / 1 A reduces thermal stress in fanless enclosures, while the 17 uA quiescent current helps idle-mode power budgets. Pair the TPS62130ARGTT with TLV62569 or TPS62130A family for higher current rails in the same power tree.

USB Type-C Powered Device Rails
USB Type-C sinks negotiate 5 V, 9 V, 15 V, or 20 V over CC pin; the TPS62130ARGTT can be used after the Type-C PD controller to step the negotiated voltage to a stable 3.3 V or 5 V system rail at up to 3 A. The wide 3-17 V input covers 5 V and 9 V PDO cases directly, and the small VQFN-16 (RGT) 3x3 mm package fits the space-constrained Type-C dongle and hub form factors. The power-good output drives USB-C attached LEDs and the MCU status GPIOs cleanly. Recommend pairing with TPS61288RQQR as the PD front-end.

Portable Battery-Powered Systems
The 3 V minimum input lets the TPS62130ARGTT run directly from a single-cell Li-ion or 2-cell alkaline / NiMH pack down to its 3.0 V cutoff, while its 17 V maximum also covers 2-cell Li-ion and 12 V lead-acid stacks. The 17 uA quiescent current extends battery life during sleep, and the 90% plus efficiency at moderate load minimizes runtime loss. The 3 x 3 mm VQFN package suits wearables, e-readers, and handheld instruments. Pair with TPS3700DDCR for the undervoltage lockout supervisor on the input rail.

FPGA / CPLD Core and I/O Supplies
The TPS62130ARGTT's fast transient response from DCS-Control suits the dynamic load step typical of FPGA core rails spinning between active and idle states. A 3.3 V I/O or 1.2 V core rail can be sourced from 5 V or 12 V upstream, with sub-1 uH inductor allowing dense routing around the FPGA BGA. The exposed thermal pad easily handles the multi-second 2 A bursts typical of FPGA configuration cycles. TI E2E reports this part is widely used as an FPGA companion to SoC designs in industrial controllers.

Solid-State Drive (SSD) Power Tree
Inside a small M.2 or mSATA SSD, the 3.3 V system rail typically needs to be sequenced for the NAND, controller, and DRAM at sub-1 A currents but with tight ripple and fast load steps. The TPS62130ARGTT delivers 3 A with 17 uA quiescent, plus programmable soft-start and output discharge to drive the NAND/Controller/DRAM power-on sequence. The 2.5 MHz switching keeps the converter outside of baseband noise, and the small VQFN-16 (RGT) package is ideal below the SSD PCB keep-out zones.

Industrial Sensor and PLC Modules
The 24 V industrial-bus range is stepped to 5 V / 3.3 V at the PLC input module with the TPS62130ARGTT or pin-compatible TPS62140 / TPS62150 family. The 17 V input cap covers most 12-15 V industrial rails; for higher-voltage 24 V systems the TPS62140 family is preferred. The 17 uA quiescent suits loop-powered field instruments. The exposed thermal pad provides robust operation across the -40 C to +125 C industrial temperature range required by IEC 61010.

Ghi chú thiết kế
Estimated: at VIN=12 V, VOUT=3.3 V, IOUT=3 A, power dissipation is approximately (12-3.3)*3 = 26.1 W losses converted to heat, but actual dissipation at 90% efficiency is around 1 W. With RGT package thermal resistance near 38 C/W on a 4-layer JEDEC test board, junction temperature rises approximately 38 C above ambient at 1 W, leaving plenty of margin for the 125 C TJ max. Verify on your specific PCB layout using EVM data; derate ambient above 85 C for safety.
Place the input ceramic capacitor as close as possible to PVIN and PGND pins (under 1-2 mm via length) to minimize switching noise on the input rail. Use a 22 uF X7R 25 V ceramic on PVIN and a 22 uF X7R 10 V ceramic on the output. Keep the SW node traces short and avoid routing sensitive analog signals directly above the SW plane. Connect the exposed thermal pad directly to a PGND copper island on the top layer with multiple thermal vias to inner PGND layers for heatsinking.
Avoid inductors with saturation current less than peak IOUT plus 30% headroom; undersized inductors cause DCS-Control sub-harmonic instability and audible noise at light load. Do not place an R-C snubber across SW and PGND unless required by EMI - the part is optimized for clean switching without snubbers. Ensure the FB trace is shielded from the SW node by a PGND guard ring to avoid output noise pickup that degrades load regulation.
