TPS54060DGQR Overview
A buck (step-down) converter is a switching DC-DC regulator that efficiently lowers a higher input voltage to a lower regulated output voltage by chopping the input with a power switch and averaging the resulting pulse train through an LC filter. Buck converters sit inside the broader switching regulator → DC-DC converter → power management IC hierarchy. They are preferred over linear regulators whenever the input-to-output voltage differential is large, because switching conversion avoids the linear regulator's I·(Vin-Vout) thermal loss. The TPS54060's low-quiescent Eco-Mode pulse skipping further improves light-load efficiency, making it well-suited to always-on applications.
Key features include 116 µA operating quiescent current, 1.3 µA shutdown supply current via the enable pin, internal 0.8-V reference with ±1% accuracy, frequency synchronization to an external clock, power-good output, internal soft start, cycle-by-cycle current limit, and thermal shutdown. Current-mode control provides simple external compensation and flexible component selection, allowing engineers to optimize the loop for ceramic or electrolytic output capacitors. The integrated high-side MOSFET eliminates external switch selection and reduces BOM count.
Typical applications include 24-V industrial automation rails, 48-V telecom and PoE point-of-load converters, HVAC and building automation sensor supplies, eMeter and grid infrastructure auxiliary rails, battery charging and management systems, and after-market automotive accessories operating from 12-V/24-V buses. The wide VIN range also suits distributed 12-V to 5-V/3.3-V/2.5-V intermediate buses in factory and process-control equipment.
When designing with this part, place the bootstrap capacitor (BST to SW) close to the IC and keep the high-current SW loop area minimal to reduce ringing and EMI. Use the WEBENCH Power Designer tool to generate a complete reference schematic, compensation network, and inductor selection. The PowerPAD must be soldered to a sufficient copper area for thermal dissipation — up to ~1 W is achievable with a 1-in² copper pad on a standard 4-layer FR-4 board.

Typical Applications
TPS54060DGQR is suitable for 7 applications: 24-V Industrial Automation Rails, 48-V Telecom and PoE Point-of-Load Converters, HVAC and Building Automation Sensor Supplies, Smart E-Meter and Grid Infrastructure Auxiliary Rails, 12-V/24-V After-Market Automotive Accessories, Battery Charging and Management Systems, Distributed 12-V to 5-V/3.3-V/2.5-V Intermediate Buses.
24-V Industrial Automation Rails
The TPS54060DGQR's 3.5-60 V input range directly accepts 24-V industrial bus voltage with substantial margin for transients, while the integrated 200-mΩ MOSFET and 0.5-A output cleanly power PLC I/O, sensor signal chains, and isolated communication transceivers. Eco-Mode pulse skipping holds quiescent current at 116 µA during standby, extending efficiency in always-on industrial nodes. According to TI's SWIFT family datasheet, the 100 kHz to 2.5 MHz adjustable switching frequency lets designers shrink inductors for DIN-rail-mounted PCBs where vertical real estate matters most.
Recommended
48-V Telecom and PoE Point-of-Load Converters
PoE Powered Devices (PD) present a nominal 48-V input with significant cable-induced transients, and the TPS54060DGQR survives the full 60-V maximum with margin. Its high-side-only switch topology requires only a Schottky diode on the low side, simplifying synchronous-replacement architectures while keeping BOM low. Per TI's WEBENCH design tool, the 2.5-MHz max switching frequency supports the small LC filters demanded by compact PoE modules. The 1.3-µA shutdown current extends standby for IEEE 802.3az energy-efficient Ethernet compliance.
Recommended
HVAC and Building Automation Sensor Supplies
Building automation nodes (thermostats, CO2 sensors, occupancy detectors) are often wired to 24-VAC rectified rails that present wide DC variations. The TPS54060DGQR's 3.5-60 V input tolerates these fluctuations without additional pre-regulation. Eco-Mode's 116-µA quiescent supports the long standby required by wireless battery-backed sensors. According to TI's design notes, the wide output range (0.8-58 V) allows one design to serve 3.3-V microcontroller rails, 5-V analog supplies, and 12-V actuator drivers with minor resistor-divider swaps, reducing SKU proliferation.
Recommended
Smart E-Meter and Grid Infrastructure Auxiliary Rails
Smart electricity meters derive auxiliary power from the line voltage, producing a poorly regulated intermediate DC rail that commonly ranges from 12 V to 50 V. The TPS54060DGQR's 60-V maximum covers this range with headroom, and its internal cycle-by-cycle current limit and thermal shutdown provide the fault tolerance required for unattended grid equipment. Per TI application note SLVA477, the integrated high-side switch and small MSOP-10 footprint suit the dense PCB layouts of single-phase meter modules. Power-good output enables deterministic supervision by the meter's MCU.
Recommended
12-V/24-V After-Market Automotive Accessories
Aftermarket automotive accessories must survive load-dump transients up to ~40 V on 12-V systems and double that on 24-V truck systems. The TPS54060DGQR's 60-V absolute maximum input absorbs these spikes without additional TVS clamping (although a TVS is still recommended for ISO 7637-2 compliance). Eco-Mode extends battery life when the engine is off, reducing parasitic drain. According to the TI SWIFT family overview, the 200-mΩ high-side MOSFET keeps junction temperature rise modest in the under-hood environment when the PowerPAD is soldered to adequate copper.
Recommended
Battery Charging and Management Systems
Auxiliary battery chargers and DC-DC conversion stages in 12-V/24-V lead-acid or Li-ion battery stacks use the TPS54060DGQR to step the pack voltage down to logic-level rails. The wide VIN tolerates the pack's full charge voltage range, and the 1.3-µA shutdown current enables true zero-draw sleep modes. Per TI's TPS54060EVM user guide, cycle-by-cycle current limit and the soft-start pin protect battery cells against inrush faults. Power-good signaling also informs the battery management MCU of valid conversion status.
Recommended
Distributed 12-V to 5-V/3.3-V/2.5-V Intermediate Buses
In factory and process-control equipment, a 12-V or 24-V distribution bus powers multiple lower-voltage rails through point-of-load (POL) converters. The TPS54060DGQR's 0.8-58 V adjustable output covers all common logic rails, and the small HVSSOP-10 footprint lets engineers place converters close to their loads for optimal transient response. Per TI's SWIFT family design guide, the external frequency sync capability coordinates multiple POLs to avoid beat-frequency EMI in dense cabinet layouts.

Design Notes
The TPS54060DGQR's HVSSOP PowerPAD is the primary heat-dissipation path; the datasheet specifies RθJA of approximately 50 °C/W on a 4-layer JEDEC test board with 1-in² PowerPAD copper. Per TI's layout guide (SLVA477), keep the high-current SW loop (VIN → internal MOSFET → SW → external diode → PGND) tight, place the bootstrap capacitor (BST-to-SW) within 5 mm of pins 9-10, and use a PGND copper island under the IC connected to PowerPAD with multiple thermal vias. Failing to observe these can add 20 °C of junction rise and reduce efficiency 2-3% at full load.
Estimated: at VIN=24 V, VOUT=5 V, IOUT=0.5 A, power dissipation is approximately (24-5) × 0.5 + VIN × IQ ≈ 9.6 W. With the integrated 200-mΩ MOSFET and 90% typical efficiency, junction rise should remain manageable on a 1-in² copper pad. For VIN-VOUT differentials above 15 V at full load, derate output current or add airflow; the thermal shutdown threshold (~165 °C junction) protects against catastrophic failure but should not be relied on in normal operation.
Do not omit the bootstrap capacitor (typically 0.1 µF X7R between BST and SW) — without it the high-side MOSFET lacks gate drive and the regulator will not start. Ensure the EN pin is pulled above the rising threshold (~1.2 V) for reliable startup across temperature. The SS/TR pin must have a capacitor (typically 10-100 nF) to limit inrush; do NOT leave SS/TR floating. In Eco-Mode, the SW node stays low until the next pulse, so ripple may slightly increase at microamp loads — this is normal, not a fault.
For EMI-sensitive designs, place the input bulk capacitor close to VIN (pin 1) and connect its return directly to the PowerPAD/PGND copper island to minimize the input current loop. Use an external SYNC clock to set a fixed frequency that avoids sensitive bands (e.g. 400 kHz for AM-bands, 1.7 MHz for shortwave). The datasheet suggests shielded ferrite inductors and a snubber (RC across the Schottky) can further reduce SW-node ringing by 5-10 dB at 100-200 MHz.
Compliance Information
RoHS compliant per TI datasheet. Standard DGQR is industrial/consumer grade; for AEC-Q100 qualification choose TPS54060QDRCRQ1 (different VSON-10 package, NOT a drop-in).
