Product details
Overview
TPS57060QDGQRQ1 from Texas Instruments is an automotive-grade 60-V, 0.5-A synchronous step-down DC-DC converter with integrated 200-mΩ high-side MOSFET, Eco-mode™ pulse-skipping control, and 116-μA no-load quiescent current. It delivers regulated 3.3-V output from 12-V input at 500 kHz in automotive infotainment power rails.
For engineers reviewing the TPS57060QDGQRQ1 datasheet, TPS57060QDGQRQ1 pinout, TPS57060QDGQRQ1 application, or TPS57060QDGQRQ1 equivalent, key selection considerations include AEC-Q100 Grade 1 qualification (–40°C to +125°C), adjustable UVLO via EN pin, open-drain PWRGD with 92–109% voltage window, and RT/CLK synchronization capability for EMI-sensitive automotive systems.
Technical Context
The TPS57060QDGQRQ1 implements constant-frequency peak-current-mode control with internal slope compensation to prevent subharmonic oscillation across 0–100% duty cycle. Its error amplifier drives COMP with 97-μ℧ transconductance and 2700-kHz bandwidth, enabling stable loop response with minimal external compensation.
It integrates boot UVLO (2.1 V threshold), frequency foldback during overload, thermal shutdown at 182°C, and a dedicated slow-start/tracking (SS/TR) pin with 2-μA charge current for controlled ramp-up and sequencing. The PWRGD comparator monitors VSENSE against 0.8-V reference with ±2% hysteresis and asserts low on under- or overvoltage faults.
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 microcontrollers, sensors, and display logic in ADAS modules. |
| Quiescent Current | 116 μA at no load - enables always-on functionality in body electronics without excessive battery drain. |
| Switching Frequency | 100 kHz to 2.5 MHz - adjustable via RT resistor or external clock; 500 kHz typical for optimal size/efficiency trade-off. |
| Voltage Reference | 0.8 V ±1% - sets precise output regulation point; used with external resistor divider for adjustable outputs. |
| Power Good Threshold | 92% to 109% of nominal VOUT - provides robust fault detection with built-in hysteresis for noise immunity. |
| Shutdown Current | 1.3 μA at 25°C - ensures ultra-low leakage during vehicle sleep mode. |
| Thermal Shutdown | 182°C junction temperature - protects against sustained overload or poor PCB thermal design. |
Pinout & Package
TPS57060QDGQRQ1 is housed in a 10-pin MSOP-PowerPAD™ (DGQ) package with 3.00 mm × 3.00 mm body and exposed thermal pad (Pin 11) requiring solder connection to PCB ground plane for thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PH (Pin 10) | High-side MOSFET source | Switch node connecting to inductor; must be routed with low-inductance layout to minimize switching noise. |
| BOOT (Pin 1) | Bootstrap gate drive supply | Requires 0.1-μF X7R/X5R ceramic capacitor to PH; enables 100% duty-cycle operation when BOOT-PH ≥ 2.1 V. |
| VIN (Pin 2) | Main input supply | Accepts 3.5–60 V; internal UVLO defaults to 2.5 V but is adjustable via EN pin resistors. |
| GND (Pin 9) | Analog/digital ground reference | Common return for control circuitry; must be connected to PowerPAD for proper bias and thermal path. |
| VSENSE (Pin 7) | Feedback input | Inverting input of transconductance error amplifier; compares scaled output voltage to 0.8-V reference. |
| COMP (Pin 8) | Error amplifier output | Drives PWM comparator; connects to RC network for loop compensation and stability tuning. |
| EN (Pin 3) | Enable/UVLO control | Pulled up internally; <1.2 V disables device; external resistor divider adjusts UVLO threshold and hysteresis. |
| RT/CLK (Pin 5) | Frequency setting/sync input | Resistor-to-ground sets fSW (100–2500 kHz); pulled above 2.2 V switches to external clock sync mode. |
| SS/TR (Pin 4) | Slow-start/tracking control | Capacitor sets soft-start time; voltage override enables power sequencing with other rails. |
| PWRGD (Pin 6) | Open-drain power-good flag | Asserts low if VOUT falls below 92% or rises above 109% of nominal; requires external pullup resistor. |
Key Features
| Feature | Design Value |
|---|---|
| Eco-mode™ pulse-skipping | Reduces light-load efficiency loss by skipping switching cycles while maintaining regulation - critical for automotive standby power budgets. |
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C ambient operation with HBM ±2 kV and CDM ±500 V ESD robustness - meets automotive safety-critical requirements. |
| Integrated boot diode | Eliminates external bootstrap diode, reducing BOM count and PCB area - simplifies layout in space-constrained head units and camera modules. |
| Adjustable UVLO with hysteresis | EN pin supports two-resistor configuration to set custom start/stop thresholds - prevents brownout oscillation during cold-crank events. |
| Overvoltage protection via PWRGD | OV comparator disables high-side MOSFET until VOUT drops below 107%, preventing damage to downstream 3.3-V logic. |
| Thermal foldback and shutdown | Reduces fSW during overload and shuts down at 182°C - protects against sustained short-circuit or inadequate heatsinking. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM61480QRNTRQ1 | Higher 3.5-A output current, 4-V to 36-V input, fixed 500-kHz fSW, no Eco-mode™, higher 18-μA IQ | Better suited for higher-power ADAS ECUs; lacks light-load efficiency optimization for always-on subsystems | Select when >0.5-A output or tighter input range suffices and Eco-mode™ is not required |
| TPS54360BQDDARQ1 | Same 60-V max input, 3.5-A output, 100-kHz to 2.5-MHz fSW, Eco-mode™, 14.5-μA IQ, larger SOIC-8 package | Higher current capacity and same light-load efficiency; SOIC-8 footprint increases PCB area vs DGQ's 3×3 mm | Choose when board space allows larger package and >0.5-A delivery is needed without redesign |

FAQ
What is the maximum input voltage rating for the TPS57060QDGQRQ1?
The TPS57060QDGQRQ1 has an absolute maximum input voltage rating of 65 V on the VIN pin, with recommended operating range from 3.5 V to 60 V. This allows direct connection to 12-V, 24-V, and 48-V automotive battery systems while surviving load-dump transients up to 65 V per ISO 7637-2 Pulse 5a. Operation beyond 60 V is not recommended for long-term reliability.
How does the Eco-mode™ function improve efficiency in the TPS57060QDGQRQ1?
Eco-mode™ in the TPS57060QDGQRQ1 enables pulse-skipping operation at light loads, reducing switching losses and achieving 116-μA quiescent current. When output current drops below ~50 mA, the controller skips cycles while maintaining regulation - directly lowering power consumption in always-on automotive subsystems such as CAN wake-up receivers or sensor interfaces powered by the TPS57060QDGQRQ1.
Can the TPS57060QDGQRQ1 synchronize to an external clock, and how is it configured?
Yes, the TPS57060QDGQRQ1 synchronizes to an external clock via the RT/CLK pin. When pulled above 2.2 V (with hysteresis), the internal oscillator amplifier disables and the pin becomes a high-impedance clock input to the internal PLL. Clock edges must meet minimum 40-ns pulse width; loss of clock reverts automatically to resistor-set mode. This feature helps suppress EMI in noise-sensitive ADAS and infotainment systems using the TPS57060QDGQRQ1.
What is the purpose of the SS/TR pin on the TPS57060QDGQRQ1, and how is it used for power sequencing?
The SS/TR pin on the TPS57060QDGQRQ1 controls output voltage ramp rate during startup and enables tracking of another supply rail. A capacitor to ground sets soft-start time; applying an external voltage (e.g., from another regulator's output) allows the TPS57060QDGQRQ1 output to track that rail. This ensures ordered power-up in multi-rail systems - for example, sequencing 3.3-V logic before 1.8-V core in an infotainment SoC - preventing latch-up or I/O contention.
Does the TPS57060QDGQRQ1 provide overvoltage protection, and how does it respond to an overvoltage condition?
Yes, the TPS57060QDGQRQ1 includes overvoltage protection via its PWRGD comparator. When VSENSE exceeds 109% of nominal, PWRGD asserts low. More critically, the OV comparator immediately disables the high-side MOSFET and holds it off until VOUT falls below 107%, preventing damage to downstream 3.3-V or 5-V logic. This fast OV response is integral to the TPS57060QDGQRQ1's fault-handling architecture and does not require external components.
