Product details
Overview
TPS57160ZQDGQRQ1 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 116-μA quiescent current. It operates from 3.5 V to 60 V input, delivers regulated 0.8-V–60-V output via external resistor divider, and targets 12-V/24-V/48-V industrial and automotive power rails.
For engineers reviewing the TPS57160ZQDGQRQ1 datasheet, TPS57160ZQDGQRQ1 pinout, TPS57160ZQDGQRQ1 application, or TPS57160ZQDGQRQ1 equivalent, key selection criteria include its AEC-Q100 qualified Z-suffix MSOP-PowerPAD™ package with improved delamination resistance, 100-kHz–2.5-MHz adjustable switching frequency, and open-drain PWRGD monitoring of ±8% output voltage deviation.
Technical Context
This device implements constant-frequency peak-current-mode control with internal slope compensation to prevent subharmonic oscillation across full duty cycle range. The error amplifier drives COMP to regulate VSENSE against a 0.8-V reference, while RT/CLK supports both resistor-set frequency tuning and PLL-based external clock synchronization.
It integrates boot UVLO (2.1 V threshold), thermal shutdown (182°C), and overload recovery with frequency foldback. The SS/TR pin enables programmable slow-start, sequencing, or tracking via external capacitor/resistor networks, and discharges during fault conditions for repeatable restarts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.5 V to 60 V - supports wide automotive and industrial supply rails including cold-crank and load-dump transients. |
| Output Current | 1.5 A continuous - sufficient for powering microcontrollers, sensors, and interface ICs in safety-critical systems. |
| Switching Frequency | 100 kHz to 2.5 MHz - adjustable via RT/CLK resistor or external clock; enables optimization of efficiency vs. size for 1–10 μH inductors. |
| Quiescent Current | 116 μA - enables ultra-low-power operation in always-on automotive modules without battery drain. |
| Shutdown Current | 1.5 μA - ensures minimal leakage when disabled via EN pin, critical for long-term vehicle sleep modes. |
| Reference Voltage | 0.8 V ±1% - sets precise output regulation point; allows accurate 3.3 V, 5 V, or custom rail generation with external resistive divider. |
| Power-Good Threshold | 92%–109% of nominal VOUT - provides robust fault detection with hysteresis to avoid false triggers during transient events. |
Pinout & Package
The TPS57160ZQDGQRQ1 uses a thermally enhanced 10-pin MSOP-PowerPAD™ (DGQ) package with 3.00 mm × 3.00 mm body size and exposed thermal pad electrically connected to GND for optimal heat dissipation in automotive environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PH | High-side MOSFET source | Connects to inductor node; carries full switching current and defines buck topology node voltage swing. |
| VIN | Main input supply | Accepts 3.5–60 V; powers internal bias circuitry and high-side gate driver through bootstrap network. |
| GND | Power and signal ground | Reference for all analog circuits; must be tied to exposed thermal pad for thermal and EMI performance. |
| BOOT | Bootstrap capacitor connection | Requires 0.1-μF X7R/X5R ceramic cap to PH; supplies gate drive voltage for high-side MOSFET. |
| VSENSE | Error amplifier inverting input | Monitors feedback voltage from output divider; regulates output by comparing to 0.8-V internal reference. |
| COMP | Error amplifier output | Drives current-mode PWM comparator; connects to external compensation network for loop stability. |
| EN | Enable and UVLO control | Pull below 1.25 V to disable; float or bias with resistor divider to adjust input undervoltage lockout threshold. |
| RT/CLK | Frequency setting/sync input | Resistor-to-ground sets fSW (100 kHz–2.5 MHz); external clock edges synchronize switching via PLL. |
| SS/TR | Slow-start/tracking control | Capacitor sets soft-start time; resistor divider enables power sequencing or output voltage tracking. |
| PWRGD | Open-drain power-good indicator | Asserts low when VOUT falls below 92% or rises above 109%; requires external pullup for logic-level signaling. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Qualified Z-Suffix | Enhanced delamination resistance in MSOP-PowerPAD™ package improves long-term reliability under thermal cycling in automotive under-hood applications. |
| Eco-mode™ Pulse-Skipping | Reduces no-load input current to 116 μA by skipping switch cycles-critical for battery-powered telematics and ADAS modules. |
| Integrated Boot Recharge Diode | Eliminates external diode requirement; simplifies layout and reduces BOM count while maintaining efficient high-duty-cycle operation. |
| Adjustable UVLO with Hysteresis | EN pin biasing allows user-defined input voltage turn-on/turn-off thresholds with programmable hysteresis to reject supply noise. |
| Overvoltage Fault Protection | Power-good comparator disables high-side MOSFET when VOUT exceeds 109%, preventing downstream component damage during transient overvoltage. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM5164QPWPRQ1 | 42-V max input, 0.6-A output, 1.2-MHz fixed frequency, no PWRGD, higher IQ (25 μA) | Better suited for lower-power, cost-sensitive modules where 1.5-A output is unnecessary | Select when board space is constrained and 0.6-A output suffices; verify absence of PWRGD does not impact system fault handling. |
| TPS54360BQDDARQ1 | 60-V input, 3.5-A output, 100-kHz–2.5-MHz adjustable fSW, 145-μA IQ, no Eco-mode | Higher current capability for multi-rail systems; lacks light-load efficiency optimization | Choose when >1.5-A output is required or when Eco-mode is not needed; note larger DDA package footprint. |
Compared with LM5164QPWPRQ1 and TPS54360BQDDARQ1, the TPS57160ZQDGQRQ1 uniquely balances 1.5-A output, ultra-low 116-μA quiescent current, and AEC-Q100 Z-suffix reliability in a 3-mm × 3-mm MSOP-PowerPAD™ package-making it optimal for mid-power automotive subsystems demanding efficiency, small size, and long-term robustness.

FAQ
What is the maximum input voltage rating for the TPS57160ZQDGQRQ1?
The TPS57160ZQDGQRQ1 has an absolute maximum input voltage rating of 65 V, with recommended operating range from 3.5 V to 60 V. This 60-V rating enables robust operation in automotive systems experiencing load dump transients up to ISO 7637-2 Pulse 5a, and supports industrial 48-V DC distribution buses without external clamping.
Does the TPS57160ZQDGQRQ1 require an external bootstrap diode?
No, the TPS57160ZQDGQRQ1 integrates the bootstrap recharge diode internally. A 0.1-μF X7R/X5R ceramic capacitor must be placed between BOOT and PH pins, but no external diode is needed-reducing component count, PCB area, and potential failure points in automotive designs.
How does the Eco-mode™ control in the TPS57160ZQDGQRQ1 improve light-load efficiency?
The TPS57160ZQDGQRQ1 uses Eco-mode™ pulse-skipping to reduce switching activity at light loads, lowering input supply current to 116 μA. Unlike forced PWM, this mode skips entire switching cycles while maintaining regulation, eliminating low-frequency ripple and minimizing losses in inductors and MOSFETs-ideal for always-on automotive modules.
What is the purpose of the Z-suffix in TPS57160ZQDGQRQ1?
The Z-suffix in TPS57160ZQDGQRQ1 denotes an enhanced manufacturing process for the MSOP-PowerPAD™ (DGQ) package that significantly improves resistance to delamination under thermal stress. This is critical for automotive under-hood applications subject to repeated thermal cycling between –40°C and +125°C ambient.
Can the TPS57160ZQDGQRQ1 synchronize to an external clock signal?
Yes, the TPS57160ZQDGQRQ1 supports external clock synchronization via the RT/CLK pin. When driven with a clock signal exceeding the internal PLL upper threshold (1.9–2.2 V), the pin transitions from resistor-set mode to high-impedance clock input, enabling precise switching alignment to system timing references-reducing EMI in noise-sensitive applications like camera or radar modules.
