Product details
Overview
TPS54060DGQR 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 for light-load efficiency, 116-μA operating quiescent current, and adjustable 100-kHz to 2.5-MHz switching frequency. It delivers regulated 3.3-V output at 500 mA in industrial power supplies requiring wide-input-voltage operation.
For engineers reviewing the TPS54060DGQR datasheet, TPS54060DGQR pinout, TPS54060DGQR application, or TPS54060DGQR equivalent, key selection considerations include input voltage range (3.5–60 V), UVLO adjustability via EN pin, PWRGD open-drain power-good signaling, slow-start/sequencing capability via SS/TR, and thermal performance in the 3-mm × 3-mm VSON package.
Technical Context
The TPS54060DGQR implements constant-frequency peak-current-mode control with internal slope compensation to prevent subharmonic oscillation across duty cycles. Its error amplifier drives COMP with transconductance of 97 μS (typ) and 26 μS during slow start, enabling stable loop response with minimal external compensation.
It integrates boot UVLO (2.1 V threshold), frequency foldback during overload, thermal shutdown (182°C), and an open-drain PWRGD comparator asserting outside 94–107% of nominal VOUT. The RT/CLK pin supports both resistor-set frequency tuning and external clock synchronization via PLL lock-in (100 μs typical).
Key Specifications

|---|---|
| Input Voltage Range | 3.5 V to 60 V - supports 12-V, 24-V, and 48-V industrial bus rails without pre-regulation |
| Output Current | 0.5 A continuous - sufficient for powering microcontrollers, sensors, and interface ICs in low-power systems |
| Quiescent Current | 116 μA - enables >1-year battery life in always-on IoT nodes with light-load operation |
| Switching Frequency | 100 kHz to 2.5 MHz - allows optimization of inductor size (e.g., 10–47 μH) and EMI filtering |
| Reference Voltage | 0.8 V ±1.6% - sets minimum output voltage; adjustable up to 57 V via external resistor divider on VSENSE |
| High-Side RDS(on) | 200 mΩ @ 12 V - reduces conduction loss and improves full-load efficiency over discrete solutions |
| PWRGD Threshold | 94–107% of VREF - provides precise power-good assertion for system sequencing and fault detection |
| Shutdown Current | 1.3 μA - enables ultra-low standby power in automotive accessory modules during ignition-off |
Pinout & Package
The TPS54060DGQR is housed in a thermally enhanced 3-mm × 3-mm, 10-pin VSON (DRC) package with exposed thermal pad electrically connected to GND. This package achieves 40°C/W junction-to-ambient thermal resistance on standard PCB layouts, supporting reliable 0.5-A operation without forced airflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BOOT | Bootstrap supply node | Connects to 0.1-μF ceramic capacitor between BOOT and PH; enables gate drive for integrated high-side MOSFET |
| COMP | Error amplifier output | Drives PWM comparator; connects to RC network for loop compensation and stability |
| EN | Enable / UVLO control | Pull below 1.2 V to disable; internal pull-up allows floating-enable; resistor divider adjusts UVLO threshold |

| PH | Switch node | Source of internal high-side MOSFET; connects to inductor and catch diode/capacitor |
| PWRGD | Open-drain power-good | Asserts low if VOUT < 94% or >107% of setpoint; requires external pull-up for logic-level signaling |
| RT/CLK | Frequency control | Resistor-to-GND sets fSW; external clock edges synchronize switching via PLL when pulled above threshold |
| SS/TR | Slow-start / tracking | Capacitor sets output ramp time; voltage override enables supply sequencing with other rails |
| VIN | Main input supply | Accepts 3.5–60 V; includes internal 2.5-V UVLO with adjustable hysteresis via EN pin |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM5164QDDARQ1 | Automotive-grade AEC-Q100 qualified; 65-V max input; 0.6-A output; higher 250-μA IQ | Required for automotive safety-critical systems; wider temperature range (–40°C to 150°C) | Select when AEC-Q100 qualification, extended temp, or higher output current is mandatory |
| MP2451DT-LF-Z | 36-V max input; 0.6-A output; fixed 2-MHz fSW; no PWRGD or SS/TR; 250-μA IQ | Suitable for cost-sensitive consumer electronics where sequencing and power-good are not required | Select when input ≤36 V, fixed frequency suffices, and BOM simplicity outweighs feature set |
Compared with LM5164QDDARQ1, the TPS54060DGQR offers lower quiescent current and flexible frequency control but lacks automotive qualification; compared with MP2451DT-LF-Z, it provides superior input voltage range, precision PWRGD, and programmable soft-start-critical for industrial and automotive aftermarket use cases.

FAQ
What is the maximum input voltage the TPS54060DGQR can safely handle?
The TPS54060DGQR has an absolute maximum input voltage rating of 65 V, with recommended operation from 3.5 V to 60 V. It is designed to withstand automotive load-dump transients up to 65 V without damage, making it suitable for 12-V, 24-V, and 48-V industrial and automotive systems. Operation beyond 60 V should be limited to transient conditions only and must comply with TI's absolute maximum ratings.
How does the Eco-Mode™ function improve efficiency in the TPS54060DGQR?
The TPS54060DGQR enters Eco-Mode™ pulse-skipping at light loads to reduce switching and gate-drive losses. When output current drops below ~20 mA (dependent on inductor value), the device clamps COMP at 500 mV and inhibits switching until VOUT decays sufficiently to trigger a recharge pulse. This lowers operating quiescent current to 116 μA, enabling >85% efficiency at 10 mA load-critical for battery-backed or energy-harvested systems.
Can the TPS54060DGQR be synchronized to an external clock signal?
Yes, the TPS54060DGQR supports external clock synchronization via its RT/CLK pin. When pulled above the PLL upper threshold (~2.5 V), the internal oscillator amplifier disables and the pin becomes a high-impedance clock input. The internal PLL locks to external clock edges (300–2200 kHz), enabling deterministic switching alignment for EMI reduction in multi-rail systems. Lock-in time is typically 100 μs.
What is the purpose of the SS/TR pin on the TPS54060DGQR?
The SS/TR (Slow-Start/Tracking) pin on the TPS54060DGQR controls output voltage ramp rate during startup and enables supply sequencing. Connecting a capacitor to ground sets soft-start time; applying an external voltage (e.g., from another rail's SS pin) allows tracking for matched rise/fall behavior. During faults or shutdown, the pin discharges to ensure repeatable restart-preventing erratic behavior after thermal or UVLO events.
Does the TPS54060DGQR require an external bootstrap diode?
No, the TPS54060DGQR integrates the bootstrap diode internally. A 0.1-μF ceramic capacitor (X7R/X5R, ≥10 V) is required between BOOT and PH pins to provide gate drive voltage for the high-side MOSFET. The integrated diode eliminates the need for an external component, reducing board area, BOM count, and potential failure points-particularly beneficial in compact industrial and automotive modules.
