Product details
Overview
TPS54060ADGQ 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™ for light-load efficiency, adjustable 100 kHz–2.5 MHz switching frequency via RT/CLK pin, and 0.8-V internal reference - used in industrial power rails requiring wide VIN range and low quiescent current.
For engineers reviewing the TPS54060ADGQ datasheet, TPS54060ADGQ pinout, TPS54060ADGQ application, or TPS54060ADGQ equivalent, key selection considerations include input UVLO adjustability via EN pin, PWRGD open-drain monitoring (94–107% VREF window), BOOT-PH bootstrap management, slow-start/sequencing capability via SS/TR, and thermal shutdown protection at 182°C.
Technical Context
The TPS54060ADGQ implements constant-frequency peak-current-mode control with slope compensation to prevent subharmonic oscillation across 0–100% duty cycle. Its error amplifier features 97 μA/V transconductance (reduced during slow start) and compares VSENSE against the lower of 0.8-V internal reference or SS/TR voltage.
Switching frequency is set by an external resistor on RT/CLK (100–2500 kHz) or synchronized to an external clock; the pin includes PLL lock detection and auto-reversion to resistor mode if clock stops. The BOOT-PH UVLO (2.1 V threshold) enables high-duty-cycle operation while ensuring gate drive integrity.
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 dropout recovery down to ~2.5 V startup |
| Output Current | 0.5 A continuous - sufficient for low-power microcontrollers, sensors, and interface ICs without external heatsinking |
| Quiescent Current | 116 μA (non-switching, no load) - enables battery-backed or energy-harvesting applications with multi-week standby |
| Switching Frequency | 100 kHz to 2.5 MHz - allows optimization of inductor size (e.g., 4.7 μH at 500 kHz) and EMI filtering |
| Reference Voltage | 0.8 V ±1.6% (0.784–0.816 V) - sets output accuracy for 3.3 V, 5 V, or custom rails using standard resistor dividers |
| Power Good Window | 94–107% of VREF - provides reliable system reset signaling with hysteresis for noise immunity |
| Thermal Shutdown | 182°C junction - protects against sustained overload or poor PCB thermal design without latch-up |
Pinout & Package
VSON-10 (DGQ) package: 3.0 mm × 3.0 mm body, exposed thermal pad (Pin 11), RoHS-compliant, PowerPAD™ enhanced thermal performance (RθJA = 40°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BOOT (1) | Bootstrap supply node | Connects to 0.1-μF ceramic capacitor between BOOT and PH; monitored for UVLO to prevent high-side MOSFET failure |
| VIN (2) | Main input supply | Accepts 3.5–60 V; powers internal circuitry and high-side driver; requires local bulk and ceramic decoupling |
| EN (3) | Enable / UVLO control | Pull below 1.25 V to disable; internal pull-up enables default operation; two-resistor divider adjusts UVLO threshold |
| SS/TR (4) | Slow-start / tracking input | Capacitor sets soft-start time; external voltage source enables power sequencing with other rails |
| RT/CLK (5) | Frequency setting / sync input | Resistor-to-GND sets fSW; >2.2 V triggers PLL sync mode; auto-reverts to resistor mode if clock stops |
| PWRGD (6) | Open-drain power-good output | Asserts low when VOUT < 92% or >109% of target; deasserts (high-Z) when within 94–107% window |
| VSENSE (7) | Error amplifier inverting input | Feedback node for output regulation; compared to 0.8 V reference or SS/TR voltage; high-impedance (50 nA bias) |
| COMP (8) | Error amplifier output | Drives PWM comparator; connects to Type II/III compensation network; ±7 μA sink/source capability |
| GND (9) | Analog/digital ground | Common return for control circuitry; must be tied to exposed thermal pad for thermal and electrical integrity |
| PH (10) | Power switch node | Connects to inductor and catch diode (or synchronous FET); high dv/dt node requiring careful layout |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM5164QPWPRQ1 | 4.5–65 V input, 0.6 A, 1.5 MHz max fSW, no integrated boot diode, AEC-Q100 qualified | Automotive-grade replacement with higher current but requires external boot diode and stricter qualification | Choose for automotive production where AEC-Q100 compliance is mandatory; not drop-in due to different pinout and compensation requirements |
| TPS54260DGQ | Same family, 2.5 A output, identical pinout/package, higher RDS(on) (110 mΩ), same Eco-Mode and features | Higher-current variant sharing layout and firmware compatibility for scalable designs | Choose when load exceeds 0.5 A; shares same footprint and control architecture - minimal redesign needed |
Compared with LM5164QPWPRQ1, TPS54060ADGQ offers simpler layout (integrated boot diode) and lower quiescent current but lacks automotive qualification; versus TPS54260DGQ, it trades current capability for smaller solution size and lower cost in sub-0.5 A applications.

FAQ
What is the minimum input voltage required for TPS54060ADGQ to start switching?
The TPS54060ADGQ has an internally set undervoltage lockout (UVLO) threshold of 2.5 V, meaning it begins switching when VIN rises above this level. However, the EN pin can be used with external resistors to raise the effective UVLO threshold - for example, to 10 V for 12 V systems - ensuring clean startup after brownout conditions. The TPS54060ADGQ will remain enabled as long as EN voltage stays above 1.25 V.
How does the TPS54060ADGQ achieve high efficiency at light loads?
The TPS54060ADGQ uses Eco-Mode™ pulse-skipping to maintain high efficiency at light loads: it skips switching cycles when output current falls below a threshold, reducing switching losses. This lowers the no-load operating quiescent current to 116 μA. Unlike forced PWM, Eco-Mode dynamically transitions between PWM and skip modes based on load demand - a behavior confirmed in the TPS54060ADGQ datasheet Figure 1 and Section 7.3.1.
Can the TPS54060ADGQ synchronize to an external clock, and how is it configured?
Yes, the TPS54060ADGQ can synchronize to an external clock via the RT/CLK pin. When the pin voltage exceeds 2.2 V (PLL upper threshold), the internal oscillator amplifier disables and the pin becomes a high-impedance clock input to the internal PLL. If the external clock stops, the device automatically reverts to resistor-based frequency setting. The TPS54060ADGQ supports CLK input frequencies from 300 kHz to 2.2 MHz with minimum pulse width of 40 ns.
What is the role of the SS/TR pin on the TPS54060ADGQ, and how is it used for power sequencing?
The SS/TR pin on the TPS54060ADGQ controls output voltage ramp rate during startup (slow-start) or tracks another voltage rail (tracking). For sequencing, an external resistor divider or DAC voltage applied to SS/TR overrides the internal 0.8-V reference, forcing the output to follow that voltage. During faults, the TPS54060ADGQ actively discharges the SS/TR capacitor to ensure repeatable restart - a feature documented in Section 7.1 and Figure 23 of the TPS54060ADGQ datasheet.
Does the TPS54060ADGQ require an external bootstrap diode, and why or why not?
No, the TPS54060ADGQ does not require an external bootstrap diode because it integrates a boot recharge diode internally. This eliminates one external component, reduces board area, and improves reliability - especially in high-duty-cycle applications where external diode reverse recovery could cause inefficiency or noise. The integrated diode is explicitly cited in the TPS54060ADGQ datasheet Feature Description (Section 7.3.3) and Simplified Schematic.
