Product details
Overview
TPS54160QDGQRQ1 from Texas Instruments is an automotive-grade 60-V input, 1.5-A synchronous step-down DC-DC converter with integrated 200-mΩ high-side MOSFET, Eco-mode™ pulse-skipping control, and adjustable 100 kHz–2.5 MHz switching frequency. It delivers regulated 0.8-V to VIN−2 V output in industrial and automotive power supplies requiring high efficiency at light loads and robust thermal performance.
For engineers reviewing the TPS54160QDGQRQ1 datasheet, TPS54160QDGQRQ1 pinout, TPS54160QDGQRQ1 application, or TPS54160QDGQRQ1 equivalent, key selection criteria include its AEC-Q100 qualification, 116-μA no-load quiescent current, 2.5-V default UVLO with adjustable threshold via EN pin, and open-drain PWRGD output with 92%–109% voltage window detection.
Technical Context
The TPS54160QDGQRQ1 employs peak-current-mode control with internal slope compensation to prevent subharmonic oscillation across full duty-cycle range. Its error amplifier features 97 μA/V transconductance (26 μA/V during slow start) and supports external frequency compensation via COMP pin.
It integrates a bootstrap regulator with BOOT-to-PH UVLO (2.1 V) enabling 100% duty-cycle operation for low-dropout performance. The RT/CLK pin supports both resistor-set frequency tuning and PLL-based synchronization to external clock signals up to 2.2 MHz.
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 automotive and industrial bus rails without pre-regulation |
| Output Current | 1.5 A continuous - sufficient for powering microcontrollers, sensors, and communication ICs in embedded systems |
| Switching Frequency | 100 kHz to 2.5 MHz - enables optimization of inductor size and efficiency across load conditions |
| Quiescent Current | 116 μA at no load - extends battery life in always-on automotive modules |
| Voltage Reference | 0.8 V ±2% - sets minimum output voltage and defines feedback divider ratio for precise regulation |
| Power-Good Threshold | 92%–109% of nominal VOUT - provides reliable system-level fault detection with hysteresis |
| Thermal Shutdown | 182°C junction temperature - protects against sustained overload or poor PCB thermal design |
Pinout & Package
TPS54160QDGQRQ1 is housed in a thermally enhanced 10-pin MSOP (DGQ) package with exposed thermal pad, optimized for high-power-density automotive applications requiring efficient heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PH | High-side MOSFET source | Connects to inductor node; carries full switching current and requires low-inductance layout |
| GND | Power and signal ground | Must be connected to exposed thermal pad for thermal and electrical integrity |
| COMP | Error amplifier output | Interface point for external Type II/III compensation network to stabilize loop response |
| VSENSE | Inverting input of gm error amplifier | Feedback node for output voltage regulation; accepts resistor divider from VOUT |
| 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 DC; bypassed with ≥10-μF ceramic capacitor near package |
| EN | Enable and UVLO control | Pull below 1.25 V to disable; configure with resistive divider to raise UVLO threshold above 2.5 V |
| SS/TR | Slow-start and tracking input | Controls output ramp rate via external capacitor; supports sequencing with resistor divider |
| PWRGD | Open-drain power-good output | Asserts low when VSENSE < 92% or > 109% of reference; requires external pullup resistor |
| RT/CLK | Frequency setting/synchronization | Resistor-to-ground sets fSW; pulled above 2.2 V to accept external clock sync signal |
Key Features
| Feature | Design Value |
|---|---|
| Eco-mode™ pulse-skipping | Reduces no-load input current to 116 μA while maintaining regulation-critical for battery-powered automotive accessories |
| Adjustable UVLO via EN pin | Enables custom input-voltage turn-on/off thresholds using two external resistors-supports cold-cranking and brownout resilience |
| Integrated boot diode | Eliminates external bootstrap diode, reducing BOM count and layout complexity in space-constrained modules |
| Power-good (PWRGD) comparator | Detects undervoltage and overvoltage faults with programmable hysteresis-enables safe system reset and sequencing |
| Thermal shutdown with foldback | Activates at 182°C and reduces switching frequency during overload-prevents thermal runaway under short-circuit conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM5160QPWPRQ1 | Wider 3–65 V input, 1.5-A rating, but uses external MOSFETs and lacks integrated boot diode | Requires additional gate drivers and bootstrap components; better suited for higher-efficiency discrete designs | Select when board area allows discrete FET layout and higher thermal margin is needed |
| TPS54360BQDDARQ1 | Same family, pin-compatible, but rated for 3.5–60 V and 3.5-A output with 110-mΩ MOSFET | Higher current capability with identical footprint and feature set-drop-in upgrade path for increased load demand | Choose when future-proofing for >1.5 A loads or tighter thermal budgets without redesign |
Compared with LM5160QPWPRQ1, TPS54160QDGQRQ1 offers lower BOM count and smaller solution size due to integrated MOSFET and boot diode; compared with TPS54360BQDDARQ1, it trades current capacity for reduced cost and thermal footprint in 1.5-A applications.

FAQ
What is the maximum input voltage rating for the TPS54160QDGQRQ1?
The TPS54160QDGQRQ1 supports an absolute maximum input voltage of 65 V on the VIN pin, with recommended continuous operation from 3.5 V to 60 V. This 60-V rating enables direct connection to 48-V industrial buses and withstands automotive load-dump transients per ISO 7637-2 without external clamping.
How does the TPS54160QDGQRQ1 achieve low quiescent current in standby mode?
The TPS54160QDGQRQ1 achieves 116 μA operating quiescent current through Eco-mode™ pulse-skipping control, which disables switching when light-load regulation is maintained. In shutdown, its EN pin reduces supply current to 1.3 μA-critical for always-on automotive modules meeting UCISS requirements.
Can the TPS54160QDGQRQ1 synchronize to an external clock signal?
Yes-the TPS54160QDGQRQ1 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 PLL input, accepting external clock edges to align switching frequency and reduce EMI in noise-sensitive systems like infotainment or ADAS.
What is the function of the SS/TR pin on the TPS54160QDGQRQ1?
The SS/TR pin on the TPS54160QDGQRQ1 serves dual functions: connecting an external capacitor enables adjustable soft-start to limit inrush current, while configuring it with a resistor divider allows precise power-supply sequencing across multiple rails-essential for FPGA, DSP, or multi-core MCU startup timing.
Does the TPS54160QDGQRQ1 include built-in protection features?
Yes-the TPS54160QDGQRQ1 integrates thermal shutdown (182°C), frequency foldback during overload, BOOT-to-PH UVLO (2.1 V), and open-drain PWRGD output that asserts low for VSENSE outside 92%–109% of nominal. These features eliminate need for external supervision circuits in automotive and industrial designs.
