Product details
Overview
TPS54060DGQ from Texas Instruments is a 60-V, 0.5-A synchronous step-down DC-DC converter with integrated 200-mΩ high-side MOSFET, Eco-Mode™ pulse-skipping operation, 116-μA no-load quiescent current, and adjustable 100-kHz to 2.5-MHz switching frequency - used in industrial power rails requiring wide-input, low-quiescent-current regulation.
For engineers reviewing the TPS54060DGQ datasheet, TPS54060DGQ pinout, TPS54060DGQ application, or TPS54060DGQ equivalent, key selection considerations include input voltage range (3.5–60 V), output voltage adjustability down to 0.8 V, UVLO programmability via EN pin, PWRGD monitoring, and thermal performance in the 3-mm × 3-mm VSON package.
Technical Context
The TPS54060DGQ implements peak current-mode control with internal slope compensation to prevent subharmonic oscillation across duty cycles. Its Eco-Mode™ dynamically disables switching at light loads when peak inductor current falls below ~500 mV on COMP, reducing quiescent current to 116 μA while maintaining regulation.
A dedicated RT/CLK pin supports both resistor-set frequency tuning (100–2500 kHz) and external clock synchronization via PLL lock-in. The BOOT-PH UVLO circuit enables >99% effective duty cycle by monitoring gate-drive voltage and forcing refresh cycles only when BOOT-PH drops below 2.1 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.5 V to 60 V - supports 12-V, 24-V, and 48-V industrial bus inputs with margin for transients. |
| Output Current | 0.5 A continuous - delivers regulated power to microcontrollers, sensors, and interface ICs without external current boosting. |
| Quiescent Current | 116 μA (no load, Eco-Mode™ active) - extends battery life in always-on remote monitoring systems. |
| Switching Frequency | Adjustable 100 kHz to 2.5 MHz - enables optimization of inductor size vs. efficiency for space-constrained designs. |
| Internal Reference | 0.8 V ±1.5% - sets minimum output voltage; allows precise scaling to 3.3 V, 5 V, or custom rails using resistor divider. |
| Power Good Threshold | 94% to 107% of VOUT - provides reliable system reset signaling without external supervision circuitry. |
| Shutdown Current | 1.3 μA - ensures ultra-low leakage during deep sleep or fault shutdown in portable equipment. |
Pinout & Package
TPS54060DGQ is housed in a thermally enhanced 10-pin VSON (DRC) package measuring 3.00 mm × 3.00 mm with an exposed thermal pad (Pin 11) that must be soldered to PCB ground for proper thermal performance and electrical stability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input supply connection | Accepts 3.5–60 V; internal UVLO threshold is 2.5 V (adjustable via EN pin resistor divider). |
| GND | Power and signal reference | Common return path; thermal pad (Pin 11) must be electrically connected to GND plane for thermal dissipation. |
| PH | High-side MOSFET source node | Switching node tied to inductor; requires low-inductance layout to minimize EMI and ringing. |
| BOOT | Bootstrap capacitor connection | Connects to PH via 0.1-μF X7R/X5R ceramic capacitor; supplies gate drive for high-side MOSFET. |
| VSENSE | Feedback input | Inverting input of error amplifier; monitors output via resistor divider to regulate voltage to 0.8 V reference. |
| COMP | Error amplifier output | Provides compensation network connection point; controls peak current limit and loop stability. |
| EN | Enable and UVLO control | Pull below 1.2 V to disable; internal pull-up allows floating = enabled; resistor divider adjusts UVLO threshold. |
| SS/TR | Slow-start and tracking | Capacitor sets soft-start time; voltage override enables sequencing with other rails or tracking configurations. |
| RT/CLK | Frequency setting/synchronization | Resistor-to-GND sets fSW; external clock input when pulled above PLL threshold for system-level timing alignment. |
| PWRGD | Open-drain power-good indicator | Asserts low if VOUT < 94% or > 107% of nominal; requires external pull-up for logic-level signaling. |
Key Features
| Feature | Design Value |
|---|---|
| Eco-Mode™ pulse skipping | Reduces no-load input current to 116 μA by disabling switching while maintaining regulation - critical for battery-powered IoT nodes. |
| Integrated 200-mΩ high-side MOSFET | Eliminates external switch and driver, simplifying BOM and layout while enabling 0.5-A output in compact 3-mm × 3-mm footprint. |
| Adjustable UVLO with EN pin | Allows programmable input undervoltage lockout using two resistors - supports custom brown-out thresholds for 24-V or 48-V systems. |
| Open-drain PWRGD with hysteresis | Signals valid output within ±6% window (94–107%) - enables safe processor reset and rail sequencing without external comparators. |
| Thermal shutdown & frequency foldback | Protects against overload by reducing fSW and latching off above 182°C - prevents thermal runaway during short-circuit or startup faults. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM5164QPWPRQ1 | 42-V max input, 0.6-A output, 35-μA IQ, requires external MOSFETs | Better suited for automotive AEC-Q100 systems needing higher reliability grade | Choose LM5164QPWPRQ1 when AEC-Q100 qualification and lower IQ are mandatory, accepting added external FET complexity. |

FAQ
What is the maximum input voltage rating for the TPS54060DGQ?
The TPS54060DGQ has an absolute maximum input voltage rating of 65 V, with recommended operation from 3.5 V to 60 V. This 60-V upper limit supports common industrial bus voltages (24 V, 48 V) and accommodates transient surges such as load dump in automotive environments. Operation beyond 60 V risks permanent damage and violates TI's recommended conditions.
How does Eco-Mode™ reduce power consumption in the TPS54060DGQ?
Eco-Mode™ in the TPS54060DGQ reduces no-load quiescent current to 116 μA by entering pulse-skipping operation when peak inductor current falls below ~500 mV on the COMP pin. During this mode, switching halts until output droop triggers reactivation - eliminating gate drive and switching losses while maintaining regulation, which is essential for battery-backed systems.
Can the TPS54060DGQ synchronize its switching frequency to an external clock?
Yes, the TPS54060DGQ supports external clock synchronization via the RT/CLK pin. When pulled above the PLL upper threshold (~1.25 V), the internal oscillator amplifier disables and the pin becomes a high-impedance clock input. The internal PLL locks to falling edges of the external clock, enabling deterministic timing alignment across multiple regulators in noise-sensitive or EMI-constrained systems.
What is the role of the BOOT and PH pins in the TPS54060DGQ?
The BOOT and PH pins form the bootstrap gate-drive circuit for the internal high-side MOSFET. A 0.1-μF ceramic capacitor connects BOOT to PH; it is charged during the low-side conduction phase and supplies the gate voltage needed to fully enhance the MOSFET. The BOOT-PH UVLO circuit disables the FET if this voltage drops below 2.1 V, ensuring reliable operation even at near-100% duty cycle.
Does the TPS54060DGQ provide power-good status indication?
Yes, the TPS54060DGQ features an open-drain PWRGD pin that asserts low when the output voltage falls below 94% or rises above 107% of its nominal value. This provides precise, hysteresis-based power-good signaling for system reset controllers or sequencers - eliminating the need for external voltage supervisors in most applications.
