Product details
Overview
TPS57160QDGQRQ1 from Texas Instruments is an automotive-grade 60-V, 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 to 2.5-MHz switching frequency. It delivers regulated 3.3-V output at up to 1.5-A load from 12-V input with 90% peak efficiency, used in automotive infotainment power rails.
For engineers reviewing the TPS57160QDGQRQ1 datasheet, TPS57160QDGQRQ1 pinout, TPS57160QDGQRQ1 application, or TPS57160QDGQRQ1 equivalent, key selection criteria include input voltage range (3.5–60 V), light-load quiescent current (116 µA), power-good accuracy (±8% window), thermal shutdown threshold (182°C), and MSOP-PowerPAD™ package compatibility with automotive PCB layout constraints.
Technical Context
The TPS57160QDGQRQ1 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 transconductance of 97 µ℧ (typ) and 2.7 MHz bandwidth, enabling stable loop response with minimal external compensation.
It integrates boot UVLO monitoring (2.1 V threshold), frequency foldback during overload, and a dedicated open-drain PWRGD comparator with 92–109% VREF detection window. The RT/CLK pin supports both resistor-set frequency tuning and PLL-based external clock synchronization up to 2.2 MHz.
Key Specifications

Pinout & Package
TPS57160QDGQRQ1 is housed in a thermally enhanced 10-pin MSOP-PowerPAD™ (DGQ) package measuring 3.00 mm × 3.00 mm with exposed thermal pad electrically connected to GND for efficient heat dissipation in automotive under-hood environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PH | High-side MOSFET source | Switch node connecting to inductor; requires low-inductance layout to minimize EMI and ringing. |
| GND | Ground reference | Primary return path for power and signal currents; must be tied to exposed thermal pad for thermal and electrical integrity. |
| COMP | Error amplifier output | Drives PWM comparator; connects to RC compensation network for loop stability and transient response tuning. |
| VSENSE | Inverting input of error amplifier | Monitors output voltage via resistor divider; determines regulation setpoint and triggers PWRGD assertion. |
| BOOT | Bootstrap capacitor node | Supplies gate drive for high-side MOSFET; requires 0.1-µF X7R/X5R ceramic capacitor between BOOT and PH. |
| VIN | Main input supply | Accepts wide-range DC input; bypassed with ≥10-µF ceramic capacitor near package for ripple suppression. |
| EN | Enable and UVLO control | Pull below 1.25 V to disable; configured with resistive divider to raise UVLO threshold above 2.5 V for battery brownout immunity. |
| SS/TR | Slow-start/tracking control | Controls output ramp rate via external capacitor; supports sequencing with external voltage reference for multi-rail systems. |
| RT/CLK | Frequency setting/sync input | Resistor-to-ground sets switching frequency; pulled above 2.2 V to accept external clock for system-level timing alignment. |
| PWRGD | Open-drain power-good indicator | Asserts low when output deviates >8% from nominal; requires external pullup for MCU reset or enable coordination. |
Key Features
| Feature | Design Value |
|---|---|
| Eco-mode™ pulse-skipping | Reduces no-load input current to 116 µA while maintaining regulation-critical for automotive sleep-mode compliance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter 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 layout area; better suited for designs needing >1.5-A or custom FET selection. | Select LM5160QPWPRQ1 only if higher input voltage margin (>60 V) or discrete FET control is required. |
| TPS54160DGQR | Non-automotive grade (no AEC-Q100), identical 60-V/1.5-A spec, same DGQ package, but lacks PWRGD and Eco-mode™. | Not qualified for automotive use; suitable for industrial prototypes where qualification is deferred. | Choose TPS54160DGQR only for cost-sensitive non-automotive applications where AEC-Q100 and PWRGD are unnecessary. |

FAQ
What is the maximum input voltage rating for the TPS57160QDGQRQ1?
The TPS57160QDGQRQ1 has an absolute maximum input voltage rating of 65 V, with recommended operation from 3.5 V to 60 V. This 60-V upper limit supports direct connection to 48-V automotive architectures and withstands ISO 7637-2 load-dump transients without external clamping. The device's internal high-side MOSFET and gate drive circuitry are designed to operate reliably within this range, and exceeding 60 V continuously may trigger overvoltage protection or degrade long-term reliability. Always refer to Section 7.1 Absolute Maximum Ratings in the official datasheet for stress limits.
How does the Eco-mode™ function improve efficiency in the TPS57160QDGQRQ1?
The Eco-mode™ function in the TPS57160QDGQRQ1 reduces no-load input supply current to 116 µA by entering pulse-skipping mode at light loads, minimizing switching losses while maintaining output regulation. Unlike forced-PWM operation, Eco-mode™ disables switching cycles when energy demand is low, significantly lowering quiescent power-critical for automotive always-on systems like telematics or alarm controllers. This behavior is implemented via a minimum clamp on the COMP pin voltage and does not require external components. The TPS57160QDGQRQ1 resumes normal PWM operation seamlessly when load increases, ensuring fast transient response without manual intervention.
Can the TPS57160QDGQRQ1 synchronize to an external clock, and how is it configured?
Yes, the TPS57160QDGQRQ1 can synchronize to an external clock via the RT/CLK pin. When the pin voltage exceeds 2.2 V (typ), the internal oscillator amplifier disables and the pin becomes a high-impedance clock input to the internal PLL. Clock edges must meet minimum pulse width (40 ns) and frequency (300–2200 kHz) specifications. Upon loss of external clock, the device automatically reverts to resistor-set mode. This capability enables EMI reduction through synchronized switching in multi-rail systems and is confirmed in Section 8.3.4 of the TPS57160QDGQRQ1 datasheet. No firmware or configuration registers are involved-synchronization is purely analog/hardware-based.
What is the purpose of the SS/TR pin on the TPS57160QDGQRQ1, and how is it used for power sequencing?
The SS/TR (Slow-Start/Tracking) pin on the TPS57160QDGQRQ1 controls output voltage ramp rate during startup and enables supply tracking across multiple rails. Connecting a capacitor to ground sets the soft-start time; for sequencing, a resistor divider from a master supply biases SS/TR to force the TPS57160QDGQRQ1 output to follow that reference. During faults, the pin discharges to ensure repeatable restart. This functionality is essential in automotive gateways where 3.3-V digital logic must power up after 5-V analog supplies to prevent I/O contention. The SS/TR pin's 2-µA charge current and 112-µA discharge current are specified in Section 7.5 Electrical Characteristics of the TPS57160QDGQRQ1 datasheet.
Does the TPS57160QDGQRQ1 include overvoltage protection, and how does it respond to an overvoltage event?
Yes, the TPS57160QDGQRQ1 includes overvoltage (OV) protection via its PWRGD comparator, which asserts low when VSENSE exceeds 109% of the internal 0.8-V reference. More critically, when OV is detected, the high-side MOSFET is immediately disabled and masked from turning on again until VSENSE falls below 107% VREF. This prevents destructive output overshoot during load dump or feedback loop failure. The OV response is hardware-based, with no software dependency, and operates independently of the EN pin or thermal shutdown. This dual-threshold behavior (109% fault, 107% recovery) is documented in Section 7.5 Electrical Characteristics and Figure 20 of the TPS57160QDGQRQ1 datasheet.
