Product details
Overview
TPS54060QDRCRQ1 from Texas Instruments is an automotive-grade 60-V, 1.5-A step-down DC-DC converter with integrated 200-mΩ high-side MOSFET, Eco-mode™ pulse-skip control for light-load efficiency, and adjustable 100-kHz to 2.5-MHz switching frequency via RT/CLK pin. It delivers regulated output down to 0.8 V and supports power-good monitoring, slow-start sequencing, and external clock synchronization - used in 12-V/24-V automotive infotainment and industrial power rails.
For engineers reviewing the TPS54060QDRCRQ1 datasheet, TPS54060QDRCRQ1 pinout, TPS54060QDRCRQ1 application, or TPS54060QDRCRQ1 equivalent, key selection criteria include input voltage range (3.5–60 V), quiescent current (116 µA), thermal performance in DRC package (θJA = 56.5 °C/W), and AEC-Q100 qualification for automotive reliability.
Technical Context
The TPS54060QDRCRQ1 implements constant-frequency peak-current-mode control with internal transconductance error amplifier (97 µA/V), slope compensation to prevent subharmonic oscillation, and PLL-based synchronization on the RT/CLK pin. Its Eco-mode™ operation clamps COMP at 500 mV during light loads to reduce switching losses.
It integrates boot UVLO (2.1 V BOOT–PH threshold), open-drain PWRGD with 92–109% output window detection, and EN-pin-adjustable undervoltage lockout using external resistor dividers. The SS/TR pin enables programmable soft-start, tracking, and overload-recovery discharge.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.5 V to 60 V - supports wide automotive battery transients including cold-crank (4.5 V) and load-dump (60 V). |
| Output Current | 1.5 A continuous - sufficient for powering microcontrollers, sensors, and CAN transceivers in automotive ECUs. |
| Switching Frequency | 100 kHz to 2.5 MHz - adjustable via RT resistor or external clock; enables optimization of inductor size vs. EMI. |
| Quiescent Current | 116 µA - enables always-on subsystems (e.g., body control modules) without excessive battery drain. |
| Reference Voltage | 0.8 V ±2% - sets minimum output voltage; allows precise regulation of 3.3 V, 5 V, or custom rails via resistor divider. |
| Thermal Resistance (θJA) | 56.5 °C/W - measured in DRC 10-pin SON PowerPAD™ package; enables 1.5-A operation up to +125°C ambient with proper PCB copper. |
| Shutdown Current | 1.3 µA - ensures ultra-low leakage during vehicle sleep mode (e.g., ISO 16750-2 Class D). |
Pinout & Package
TPS54060QDRCRQ1 is housed in a 10-pin 3 mm × 3 mm SON (DRC) package with exposed thermal pad, optimized for high-power density and thermal dissipation in space-constrained automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PH | Power switch source node | Connects to inductor; carries full switched current; requires low-inductance layout to minimize ringing. |
| GND | Power and signal ground reference | Must be tied directly to exposed thermal pad; forms return path for high di/dt currents and error amplifier bias. |
| COMP | Error amplifier output | Interface for Type II/III compensation network; sets loop stability and transient response. |
| VSENSE | Inverting input of gm error amplifier | Monitors feedback voltage; compares against 0.8-V reference or SS/TR voltage for regulation. |
| BOOT | Bootstrap capacitor connection | Supplies gate drive for high-side MOSFET; requires 0.1-µF X7R/X5R ceramic capacitor to PH. |
| VIN | Main input supply | Accepts 3.5–60 V; powers internal circuitry and high-side driver; includes overvoltage protection to 65 V. |
| EN | Enable / UVLO adjustment | Pull below 1.25 V to disable; float or bias with resistor divider to raise UVLO threshold above 2.5 V. |
| SS/TR | Slow-start / tracking control | Capacitor sets ramp time; resistor divider enables power sequencing; discharges during fault recovery. |
| PWRGD | Open-drain power-good indicator | Asserts low when VOUT is outside 92–109% of nominal; requires external pullup for system monitoring. |
| RT/CLK | Frequency setting / sync input | Resistor-to-GND sets fSW; pulled above 2.2 V switches to external clock sync mode with PLL lock. |
Key Features
| Feature | Design Value |
|---|---|
| Eco-mode™ pulse-skip control | Maintains >85% efficiency at 10 mA load by disabling switching cycles - critical for low-power wake-up circuits. |
| AEC-Q100 Grade 1 qualification | Rated for –40°C to +125°C junction temperature - validated for engine bay and ADAS module deployment. |
| Integrated boot diode | Eliminates external Schottky diode; reduces BOM count and layout area while maintaining reliable gate drive. |
| Adjustable UVLO with hysteresis | EN pin supports user-defined start/stop thresholds (e.g., 6 V start / 5.2 V stop) to prevent brownout oscillation. |
| Overload recovery with SS/TR discharge | Automatically resets soft-start after thermal shutdown or overcurrent fault - ensures deterministic restart behavior. |
| Power-good window with hysteresis | 92–109% detection range with 2% hysteresis prevents chatter during marginal output conditions. |

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 | 42-V max input, 0.6-A output, 400-kHz fixed frequency, no Eco-mode; uses valley-current mode control. | Better suited for lower-power, cost-sensitive modules where 1.5-A capability is unnecessary. | Select when input voltage stays ≤42 V and light-load efficiency is secondary to BOM simplicity. |
| MPQ4313-AEC1 | 60-V input, 1.2-A output, 2.2-MHz max frequency, integrated compensation, no SS/TR pin. | Lacks programmable soft-start and tracking; requires external PGOOD logic for sequencing. | Choose for high-frequency designs needing smaller magnetics but accepting reduced flexibility in power sequencing. |
Compared with LM5164QPWPRQ1 and MPQ4313-AEC1, the TPS54060QDRCRQ1 uniquely combines 1.5-A capability, Eco-mode efficiency below 20 mA, and SS/TR-based sequencing - making it optimal for automotive subsystems requiring robust startup behavior and wide VIN tolerance.

FAQ
What is the maximum input voltage rating for the TPS54060QDRCRQ1?
The TPS54060QDRCRQ1 has an absolute maximum input voltage of 65 V on the VIN pin, with recommended operating range from 3.5 V to 60 V. This allows robust operation during automotive load-dump events (ISO 7637-2 Pulse 5a) and cold-crank conditions. The device includes internal overvoltage protection that disables switching if VIN exceeds 65 V.
Does the TPS54060QDRCRQ1 require an external bootstrap diode?
No, the TPS54060QDRCRQ1 integrates the boot diode internally. Only a 0.1-µF X7R/X5R ceramic capacitor between BOOT and PH pins is required to provide gate-drive voltage for the high-side MOSFET. This eliminates one external component and simplifies layout compared to discrete bootstrap solutions.
How does the Eco-mode™ operation improve light-load efficiency in the TPS54060QDRCRQ1?
The TPS54060QDRCRQ1 enters Eco-mode™ when output current drops below ~18 mA (dependent on inductor value), skipping switching cycles while maintaining regulation. This reduces gate-drive and switching losses, achieving 116 µA quiescent current and >85% efficiency at 10 mA - essential for always-on automotive subsystems.
Can the TPS54060QDRCRQ1 synchronize to an external clock?
Yes, the TPS54060QDRCRQ1 supports external clock synchronization via the RT/CLK pin. When pulled above 2.2 V, the pin transitions from resistor-set mode to high-impedance clock input, engaging the internal PLL to align PH switching edges with the falling edge of the external clock signal - reducing EMI in synchronized multi-rail systems.
What is the purpose of the SS/TR pin on the TPS54060QDRCRQ1?
The SS/TR pin on the TPS54060QDRCRQ1 serves three functions: (1) slow-start control via external capacitor to limit inrush current, (2) power-supply tracking by connecting to another regulator's feedback node, and (3) automatic discharge during overload or shutdown to ensure repeatable restart behavior after fault recovery.
