Product details
Overview
TPS57060QDRCRQ1 from Texas Instruments is an AEC-Q100 Grade 1 qualified 60-V, 0.5-A automotive buck converter with integrated 200-mΩ high-side MOSFET, Eco-mode™ pulse-skipping control, 116-μA no-load quiescent current, and adjustable 100-kHz to 2.5-MHz switching frequency - used in ADAS camera modules and infotainment power rails.
For engineers reviewing the TPS57060QDRCRQ1 datasheet, TPS57060QDRCRQ1 pinout, TPS57060QDRCRQ1 application, or TPS57060QDRCRQ1 equivalent, key selection considerations include its 3.5–60-V input range, 0.8-V reference accuracy (±0.8%), open-drain PWRGD with 92–109% output voltage window, and VSON-10 (DRC) thermal pad package for automotive thermal reliability.
Technical Context
The TPS57060QDRCRQ1 implements constant-frequency peak-current-mode control with internal slope compensation to prevent subharmonic oscillation across 0–100% duty cycle. Its Eco-mode™ enables pulse skipping below ~100 mA load, reducing light-load quiescent current to 116 μA while maintaining regulation.
It integrates a boot UVLO circuit that disables the high-side MOSFET when BOOT–PH falls below 2.1 V, enabling reliable 100% duty-cycle operation during dropout. The RT/CLK pin supports both resistor-set frequency tuning and external clock synchronization via PLL lock-in, with 40-ns minimum CLK pulse width and 100-μs lock time.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.5 V to 60 V - supports direct connection to 12 V, 24 V, and 48 V automotive battery rails with transient tolerance. |
| Output Current | 0.5 A continuous - sufficient for powering low-power ADAS sensors, display logic, and audio amplifiers. |
| Switching Frequency | 100 kHz to 2.5 MHz - adjustable via RT resistor or external clock; enables optimization of inductor size vs. efficiency. |
| Quiescent Current | 116 μA at no load - enables always-on systems (e.g., rear-view cameras) without excessive battery drain. |
| Voltage Reference | 0.8 V ±0.8% (0.792–0.808 V) - ensures tight output regulation accuracy for sensitive analog/digital loads. |
| Power Good Window | 92–109% of nominal VOUT - open-drain PWRGD asserts low on undervoltage or overvoltage fault, supporting system sequencing. |
| Thermal Performance | RθJB = 20.6 °C/W (VSON-10) - enables stable operation up to +125°C ambient in compact PCB layouts. |
Pinout & Package
VSON-10 (DRC) package: 3.0 mm × 3.0 mm body with exposed thermal pad (Pin 11), rated for 125°C ambient operation and optimized for automotive board space constraints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 BOOT | Bootstrap supply node | Connects to external 0.1-μF ceramic capacitor between BOOT and PH; powers high-side gate driver. |
| 2 VIN | Main input supply | Accepts 3.5–60 V; feeds internal LDOs, gate drivers, and control circuitry. |
| 3 EN | Enable / UVLO control | Pull ≤1.2 V to disable; internal pullup allows floating-enable; UVLO threshold adjustable with resistor divider. |
| 4 SS/TR | Slow-start / tracking input | Controls output ramp rate via external capacitor; supports power sequencing and voltage tracking with resistor networks. |
| 5 RT/CLK | Frequency set / sync input | Resistor-to-GND sets fSW; >2.2 V triggers PLL sync mode for external clock alignment. |
| 6 PWRGD | Open-drain power-good output | Asserts low if VSENSE < 92% or > 109% of nominal; requires external pullup for system monitoring. |
| 7 VSENSE | Feedback input | Inverting input of transconductance error amplifier; connects to resistor divider from output for regulation. |
| 8 COMP | Error amplifier output | Drives PWM comparator; connect Type II/III compensation network between COMP and VSENSE/GND. |
| 9 GND | Analog & power ground | Common return for control circuitry; must be connected to PCB ground plane and thermal pad. |
| 10 PH | Switch node | Source of internal high-side MOSFET; connects to inductor and BOOT capacitor; carries high di/dt switching current. |
Key Features
| Feature | Design Value |
|---|---|
| Eco-mode™ pulse skipping | Reduces no-load IQ to 116 μA while maintaining regulation - critical for automotive always-on subsystems. |
| Integrated boot recharge diode | Eliminates external diode; simplifies layout and improves reliability in high-vibration automotive environments. |
| Adjustable UVLO with hysteresis | EN pin supports custom start/stop thresholds using two resistors - prevents brownout cycling during cold-crank events. |
| Overvoltage protection masking | Disables high-side MOSFET during OV fault until VOUT drops below 107%; prevents destructive overshoot. |
| Frequency foldback | Reduces fSW during startup and overload - limits inductor current and improves fault recovery margin. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM61480QRNXTQ1 | Higher 8-A output, 4.2-V min input, no Eco-mode; uses D-CAP3 control instead of current mode. | Targets high-current ADAS ECUs, not low-power sensors; lacks pulse-skip for ultra-low IQ. | Choose LM61480QRNXTQ1 only when ≥3-A output and fast transient response are required - not a drop-in replacement. |
| TPS54360BQDDARQ1 | Same 60-V input, but 3.5-A output, fixed 2.5-V ref, no PWRGD, higher 145-μA IQ, SOIC-8 package. | Used in industrial 24-V systems; lacks automotive-grade PWRGD and tracking capability. | Choose TPS54360BQDDARQ1 for cost-sensitive non-sequencing applications where footprint and IQ are secondary. |
Compared with TPS57060QDRCRQ1, LM61480QRNXTQ1 delivers 16× more current but sacrifices light-load efficiency and sequencing flexibility, while TPS54360BQDDARQ1 offers higher output current in larger SOIC-8 but omits critical automotive features like PWRGD and SS/TR.

FAQ
What is the maximum input voltage rating for the TPS57060QDRCRQ1?
The TPS57060QDRCRQ1 has an absolute maximum input voltage rating of 65 V on the VIN pin, with recommended operation from 3.5 V to 60 V. This allows direct connection to automotive battery rails including load-dump conditions up to 60 V, making it suitable for 12-V, 24-V, and 48-V systems without external clamping.
Does the TPS57060QDRCRQ1 support external clock synchronization?
Yes, the TPS57060QDRCRQ1 supports external clock synchronization via the RT/CLK pin. When pulled above 2.2 V, the internal amplifier disables and the pin becomes a high-impedance clock input synchronized by an internal PLL with 100-μs lock time. It accepts external clocks from 300 kHz to 2.2 MHz with minimum 40-ns pulse width.
How does the PWRGD pin function on the TPS57060QDRCRQ1?
The PWRGD pin on the TPS57060QDRCRQ1 is an open-drain output that asserts low when the regulated output voltage falls below 92% or rises above 109% of nominal. It deasserts (goes high-impedance) when VSENSE is between 94% and 107%, allowing external pullup to indicate valid regulation - essential for automotive power sequencing and fault detection in the TPS57060QDRCRQ1.
What package type is used for the TPS57060QDRCRQ1?
The TPS57060QDRCRQ1 uses the VSON-10 (DRC) package: a 3.0 mm × 3.0 mm thermally enhanced leadless package with an exposed thermal pad (Pin 11). It provides RθJB = 20.6 °C/W, enabling reliable operation at +125°C ambient - certified for automotive Grade 1 (–40°C to +125°C) per AEC-Q100.
Can the TPS57060QDRCRQ1 operate in 100% duty cycle mode?
Yes, the TPS57060QDRCRQ1 supports true 100% duty cycle operation as long as the BOOT–PH voltage remains above 2.1 V. Its integrated boot UVLO circuit monitors this voltage and disables the high-side MOSFET only when BOOT–PH drops below threshold - enabling dropout operation down to VOUT + 2.1 V, critical for automotive cold-crank scenarios in the TPS57060QDRCRQ1.
