TPS54060DGQ Overview
A buck (step-down) converter is a switched-mode power supply topology that converts a higher DC input voltage to a lower DC output voltage by rapidly switching an inductor/capacitor energy-storage network. Within the broader hierarchy, the TPS54060 belongs to the power management IC category, specifically the synchronous/non-synchronous buck converter sub-family. Current-mode control provides simple external compensation, a low-ripple pulse-skip Eco-Mode enables high efficiency at light loads, and the wide VIN range makes it ideal for industrial, automotive, and battery-powered applications with high transient rails.
Key features include a precision enable pin with tighter threshold than its predecessor, internal soft-start, cycle-by-cycle current limit, thermal shutdown, and frequency foldback for short-circuit protection. The 10-pin MSOP PowerPAD package offers a low thermal resistance path that keeps junction temperature manageable even at sustained 500 mA loads. Internal compensation and minimum BOM (one inductor, input/output caps, feedback divider) simplify design-in.
Architecturally, the device uses peak current-mode control with an internal 200-mΩ high-side N-channel MOSFET. The high-side drive and bootstrap capacitor are integrated, removing external complexity. Eco-Mode operation skips switching cycles at light loads to maintain high efficiency down to a few hundred microamperes of load, while pulse-width modulation (PWM) at 2.5 MHz keeps the output ripple low and enables small inductor selection.
Typical applications include 24-V industrial sensor rails, 48-V telecom and PoE point-of-load conversion, battery-powered systems up to 60 V, HVAC fan/valve control, and small appliance motor supplies. The wide VIN range also suits automotive 12-V/24-V load-dump environments when post-transzorbs are present.
When designing with this part, ensure the bootstrap capacitor (CBST) is a high-quality 0.1-µF X7R ceramic placed close to the BST and SW pins. Keep the SW node copper area compact to minimize EMI, and use a feed-through via pattern under the thermal pad for low-junction-temperature operation.

Typical Applications
TPS54060DGQ is suitable for 6 applications: Industrial 24V Sensor and PLC Power Rails, 48V Telecom and PoE Auxiliary Power, Battery-Powered Systems Up To 60V, HVAC Fan and Valve Control Boards, Automotive 12V/24V Load-Dump Environments, Small Appliance and White Goods Motor Supplies.
Industrial 24V Sensor and PLC Power Rails
The TPS54060DGQ's 3.5 V to 60 V input range and 0.5 A output make it a strong fit for industrial 24-V sensor rails and PLC auxiliary outputs. With 60-V abs-max it tolerates the 24-V industrial common-mode transients. The 116 µA quiescent current lets the regulator stay biased continuously without draining standby budgets, while Eco-Mode keeps light-load efficiency high in sparsely-loaded PLC backplanes. Designers typically place the TPS54060DGQ between a 24-V input and a 5-V or 3.3-V sensor rail, using a 4.7 µH to 10 µH inductor. The internal 200 mΩ high-side MOSFET dissipates roughly 0.1 W at 100 mA, so no external heatsink is needed for typical sensor loads.
Recommended
48V Telecom and PoE Auxiliary Power
The TPS54060DGQ is well suited for 48-V telecom and PoE auxiliary point-of-load conversion, where the wide 3.5 V to 60 V input accepts the nominal -48 V telecom rail directly after rectification. It delivers up to 500 mA at voltages commonly used in PoE PD controllers and small-form-factor network switches. Eco-Mode pulse skipping keeps efficiency above 80% even at 10 mA loads, an important consideration for energy-efficient ethernet (EEE) idle states. The 2.5-MHz switching frequency keeps the converter above the AM-band and below typical cellular bands, simplifying EMI compliance. A typical application uses a 22 µH inductor and 4.7 µF ceramic input/output capacitors.
Recommended
Battery-Powered Systems Up To 60V
For battery-powered systems up to 60 V - such as e-bike controllers, portable medical carts, and industrial battery backups - the TPS54060DGQ provides a compact, efficient step-down solution. Its 1.3 µA shutdown current (EN low) preserves battery life in standby, and Eco-Mode keeps quiescent draw to 116 µA when active. The 60-V abs-max rating handles multi-cell Li-ion stacks (10S nominal 36 V, full charge 42 V) directly without front-end protection. At 24-V battery and 5-V output, the converter runs at approximately 85% efficiency at 200 mA load. Designers should add reverse-battery protection (Schottky or P-FET) on VIN for safety.
Recommended
HVAC Fan and Valve Control Boards
In HVAC systems running from 24-V AC rectified rails, the TPS54060DGQ provides a robust 5-V or 3.3-V supply for microcontroller logic and sensor interfaces. Its 60-V input tolerance handles the rectified 24-V AC peak (approximately 34 V) plus transient overshoot from inductive loads. The internal cycle-by-cycle current limit and thermal shutdown protect against motor inrush and stalled-fan conditions. The 10-pin PowerPAD MSOP package mounts discreetly on a crowded control board. A typical 5-V output at 300 mA load runs at about 1.4 W dissipation, which the PowerPAD handles comfortably with 1 square inch of copper pour.
Recommended
Automotive 12V/24V Load-Dump Environments
While not AEC-Q100 qualified itself, the TPS54060DGQ can serve non-safety automotive 12-V/24-V body and accessory loads (infotainment auxiliary, lighting controllers) where load-dump transients are clamped externally to <60 V. The wide VIN handles jump-start and double-battery conditions common in 24-V truck systems. The internal soft-start prevents inrush on cold-crank events. For safety-critical or AEC-Q100 applications, prefer the TPS57060QDRCRQ1 instead. Always include a TVS/transZorb on VIN rated for the load-dump profile per ISO 7637-2.
Recommended
Small Appliance and White Goods Motor Supplies
The TPS54060DGQ delivers the regulated 5-V or 3.3-V rails used by microcontroller and BLE/Wi-Fi modules in small appliances such as coffee machines, blenders, and white-goods control boards. The 60-V input accepts rectified mains (after a small step-down transformer or capacitive dropper) and the 500-mA output comfortably drives logic plus a low-power wireless radio. Eco-Mode maintains high efficiency during standby, important for ErP and energy-star standby budgets. The MSOP-10 PowerPAD package drops directly onto crowded appliance PCBs. Recommended BOM uses a 6.8 µH inductor and 2.2 µF X7R ceramic output cap.

- Pin-compatible same-package A revision upgrade (vs TPS54060ADGQR)
Design Notes
Place the 0.1 µF bootstrap capacitor (CBST) as close as possible between the BOOT and SW pins, using a short, wide trace. The high-side gate driver draws transient current through this capacitor at every switching cycle. A long trace creates parasitic inductance that can cause BOOT undervoltage and missed switching pulses. Also keep the SW node copper area compact to minimize radiated EMI; use a single ground plane with PGND and GND connected at the exposed thermal pad.
Estimated: at VIN = 24 V, VOUT = 5 V, and IOUT = 500 mA, power dissipation is approximately (24-5)*0.5 + 24*0.000116 = 9.5 W + 2.8 mW ≈ 9.5 W if the converter runs in continuous conduction. In practice Eco-Mode reduces switching loss and the high-side MOSFET Rds(on) of 200 mΩ adds about 0.05 W at 500 mA, so realistic dissipation is much lower. For sustained 500 mA loads, solder the thermal pad to at least 1 square inch of 2-oz copper to keep junction temperature rise acceptable.
Do not exceed 60 V on VIN - even brief transients above 65 V can damage the internal high-side MOSFET. Add a TVS or transZorb on VIN sized for the expected transient envelope (e.g., automotive load-dump profile). Also ensure the feedback resistor divider uses 1% tolerance parts to maintain output voltage accuracy; the internal reference is 0.8 V with ±1% tolerance. Finally, do not skip the RT/SS resistor - leaving it open disables the internal clock.
Use a star-ground topology with the exposed thermal pad as the single tie point between PGND (pin 10) and GND (pin 7). Route the input capacitor return directly to PGND and the feedback resistor divider ground to GND to avoid ground-loop noise coupling into the feedback path. Place the RT/SS resistor close to pin 4 with the compensation components (RC + C) on pin 6 referenced to GND.
