Product details
Overview
TPS54160DGQG4 from Texas Instruments is a 60-V, 1.5-A synchronous step-down DC/DC converter with integrated 200-mΩ high-side MOSFET, Eco-mode™ pulse-skipping for light-load efficiency, 116-μA operating quiescent current, and adjustable 100 kHz–2.5 MHz switching frequency - used in industrial power rails requiring wide VIN and low-noise regulation.
For engineers reviewing the TPS54160DGQG4 datasheet, TPS54160DGQG4 pinout, TPS54160DGQG4 application, or TPS54160DGQG4 equivalent, key selection considerations include UVLO adjustability via EN pin, PWRGD open-drain output (94–107% window), BOOT-PH bootstrap monitoring, RT/CLK synchronization capability, and MSOP-10 thermal-pad package compatibility with high-voltage input systems.
Technical Context
The TPS54160DGQG4 implements constant-frequency peak-current-mode control with internal slope compensation to prevent subharmonic oscillation across 0–100% duty cycle. Its error amplifier features 26 μMhos transconductance during slow start and 97 μMhos in normal operation, driving COMP to regulate VSENSE against a 0.8-V reference with ±1.6 mV accuracy over temperature.
It integrates boot capacitor recharge logic, BOOT-PH UVLO (2.1 V threshold), frequency foldback during overload, and an open-drain PWRGD comparator with independent OV/UV detection (92%/109% thresholds) and hysteresis. The EN pin supports externally adjustable UVLO with 1.25-V nominal threshold and 2.95-μA hysteresis current.
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 industrial bus inputs with dropout margin |
| Output Current | 1.5 A continuous - enables single-chip regulation for mid-power embedded subsystems |
| Quiescent Current | 116 μA - sustains >100-hour battery runtime in always-on sensor nodes |
| Switching Frequency | 100 kHz to 2.5 MHz - allows optimization of inductor size vs. EMI in space-constrained designs |
| Reference Voltage | 0.8 V ±1.6 mV - sets precise output voltage with external resistor divider (e.g., 3.3 V, 5 V, 12 V) |
| Power Good Window | 94% to 107% of VOUT - provides reliable system reset signaling without external supervision IC |
| Shutdown Current | 1.3 μA - meets ultra-low-power deep-sleep requirements in automotive telematics |
Pinout & Package
TPS54160DGQG4 uses the MSOP-10 package with exposed thermal pad (Pin 11), optimized for high-voltage thermal management in compact PCB layouts. Pin numbering follows standard top-view orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BOOT (1) | Bootstrap supply node | Drives high-side MOSFET gate; requires 0.1-μF X7R/X5R ceramic cap to PH for stable 100% duty-cycle operation |
| VIN (2) | Main power input | Accepts 3.5–60 V; internal UVLO starts at 2.5 V but adjustable via EN resistive divider |
| EN (3) | Enable & UVLO control | Pull below 1.25 V to disable; internal 1.25-V threshold enables accurate input brownout detection |
| SS/TR (4) | Slow-start / tracking input | Controls output ramp time with external capacitor; supports sequencing with resistor divider |
| RT/CLK (5) | Frequency set / sync input | Resistor-to-GND sets fSW (100–2500 kHz); external clock edges synchronize switch turn-on |
| PWRGD (6) | Open-drain power-good output | Asserts low when VOUT <94% or >107%; requires external pull-up for MCU reset signaling |
| VSENSE (7) | Feedback sense input | Inverting input of gM error amp; compares divider output to 0.8-V reference for regulation |
| COMP (8) | Error amplifier output | Drives current-mode PWM comparator; connects to RC network for loop compensation |
| GND (9) | Power ground | Reference for all analog circuitry; must be low-impedance connection to thermal pad |
| PH (10) | Switch node | Connects to inductor and BOOT capacitor; carries high di/dt switching current |
Key Features
| Feature | Design Value |
|---|---|
| Eco-mode™ pulse skipping | Reduces no-load input current to 116 μA while maintaining regulated output - critical for battery-powered remote sensors |
| Integrated 200-mΩ high-side MOSFET | Eliminates external FET and driver, reducing BOM count and layout area in 1.5-A buck designs |
| Adjustable UVLO with hysteresis | EN pin supports resistor-based UVLO threshold tuning (e.g., 7.7 V start / 6.7 V stop) for custom input rail sequencing |
| Synchronization-ready RT/CLK pin | Enables deterministic EMI reduction by locking switching edges to system clock - avoids beat frequencies in multi-rail systems |
| Overvoltage protection via PWRGD | OV comparator disables high-side FET if VOUT exceeds 109%, preventing downstream component damage during transient faults |
| Thermal shutdown & frequency foldback | 182°C junction shutdown + reduced fSW during overload limit inductor saturation and improve fault recovery margin |

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, 1-A output, 14-V UVLO fixed, no PWRGD, 3.5-μA IQ | Automotive AEC-Q100 qualified; lacks adjustable UVLO and power-good signaling | Choose for automotive-grade reliability where 42-V input suffices and system-level supervision exists |
| MP2451DT-LF-Z | 36-V max input, 0.6-A output, 2.5-V UVLO fixed, no SS/TR or RT/CLK, 260-μA IQ | Cost-optimized consumer-grade part; no sequencing, sync, or light-load efficiency features | Choose for non-critical 24-V industrial loads where size and BOM cost outweigh performance needs |
Compared with LM5164QPWPRQ1 and MP2451DT-LF-Z, the TPS54160DGQG4 delivers higher input voltage tolerance (60 V), greater output current (1.5 A), lower quiescent current (116 μA), and full feature integration (PWRGD, SS/TR, RT/CLK, adjustable UVLO), making it optimal for demanding industrial and aftermarket applications requiring robustness and design flexibility.

FAQ
What is the maximum input voltage rating for the TPS54160DGQG4?
The TPS54160DGQG4 has an absolute maximum input voltage rating of 65 V, with recommended continuous operation up to 60 V. This allows safe use in 48-V industrial systems and automotive environments subject to load-dump transients. Operation above 60 V risks permanent damage and violates TI's recommended operating conditions per SLVSB56C datasheet Section 7.1.
Does the TPS54160DGQG4 support external clock synchronization?
Yes, the TPS54160DGQG4 supports external clock synchronization via the RT/CLK pin. When driven with a clean CMOS clock signal exceeding the PLL upper threshold (1.9–2.2 V), the internal oscillator locks to the external edge, enabling deterministic EMI reduction. The device automatically reverts to resistor-set mode if clocking stops, ensuring fail-safe operation without firmware intervention.
How does the PWRGD pin function on the TPS54160DGQG4?
The PWRGD pin on the TPS54160DGQG4 is an open-drain output that asserts low when VSENSE falls below 94% or rises above 107% of the nominal output voltage. It deasserts (high-impedance) within that window, requiring an external pull-up resistor to generate a logic-high signal for MCU reset or system supervision. This dual-threshold behavior provides robust power-good monitoring without external comparators.
Can the TPS54160DGQG4 operate at 100% duty cycle?
Yes, the TPS54160DGQG4 can operate at 100% duty cycle as long as the BOOT-to-PH voltage remains above 2.1 V, enabled by its internal boot UVLO circuit. This capability supports ultra-low-dropout regulation in high-input-to-low-output voltage applications (e.g., 12 V → 3.3 V at high load), unlike many buck controllers limited to ~95% duty cycle due to bootstrap recharge constraints.
What is the purpose of the SS/TR pin on the TPS54160DGQG4?
The SS/TR pin on the TPS54160DGQG4 controls output voltage ramp rate during startup (slow-start) or tracks another supply rail (tracking). A capacitor to ground sets rise time; a resistor divider enables precise sequencing relative to other regulators. During faults (UVLO, thermal shutdown), the pin discharges fully to ensure repeatable restart behavior - a critical feature for unattended industrial equipment.
