Product details
Overview
TPS54160DGQRG4 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 116-μA quiescent current at light load, and adjustable 100 kHz–2.5 MHz switching frequency via RT/CLK pin. It delivers regulated 3.3-V output at up to 1.5 A in industrial power supplies with input ranges up to 48 V.
For engineers reviewing the TPS54160DGQRG4 datasheet, TPS54160DGQRG4 pinout, TPS54160DGQRG4 application, or TPS54160DGQRG4 equivalent, key selection criteria include UVLO threshold accuracy (1.11–1.36 V enable), PWRGD window (94–107% of VREF), BOOT-PH UVLO protection, and MSOP-10 thermal performance (θJA = 62.5°C/W).
Technical Context
The TPS54160DGQRG4 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 steady state, driving COMP to modulate high-side switch conduction time.
It integrates boot recharge diode and BOOT-PH UVLO monitoring to sustain 100% duty cycle operation when BOOT-PH ≥2.1 V. The PWRGD open-drain comparator asserts low outside 94–107% VSENSE range, while the SS/TR pin enables programmable soft-start and supply sequencing via external capacitor or resistor divider.
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 rails without pre-regulation. |
| Output Current | 1.5 A continuous - sufficient for FPGA I/O, microcontroller cores, and isolated gate drivers. |
| Quiescent Current | 116 μA - enables battery-backed systems and always-on monitoring circuits with minimal standby drain. |
| Switching Frequency | 100 kHz to 2.5 MHz - allows optimization of inductor size (e.g., 2.2 μH at 1.2 MHz) and EMI filtering. |
| Enable Threshold | 1.11–1.36 V (TPS54160A variant) - tighter UVLO hysteresis vs. TPS54160 improves input rail monitoring accuracy. |
| Power Good Window | 94–107% of VREF - provides reliable system reset signaling with ±6% tolerance on regulated output. |
| Internal Reference | 0.8 V ±1% - sets minimum output voltage and enables precise feedback resistor ratio design. |
Pinout & Package
TPS54160DGQRG4 uses the MSOP-10 package (3 mm × 3 mm) with exposed thermal pad (Pin 11) requiring PCB GND connection for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BOOT (1) | Bootstrap supply node | Connects to 0.1-μF X7R ceramic capacitor between BOOT and PH; enables high-side MOSFET gate drive above VIN. |
| VIN (2) | Main input supply | Accepts 3.5–60 V; powers internal bias circuitry and high-side switch; requires local 10-μF ceramic input capacitance. |
| EN (3) | Enable control input | Pulled up internally; pull below 1.25 V to disable; used with resistor divider to set custom UVLO threshold. |
| SS/TR (4) | Slow-start/tracking node | Charged by 2-μA current source; controls output ramp rate; supports sequencing via external voltage injection. |
| RT/CLK (5) | Frequency setting/sync input | Configures switching frequency with resistor to GND (100–2500 kHz); accepts external clock (300–2200 kHz) when pulled above 1.9 V. |
| PWRGD (6) | Open-drain power-good output | Asserts low if VSENSE <94% or >107% of 0.8 V reference; requires external pull-up for system monitoring. |
| VSENSE (7) | Feedback input | Inverting input of transconductance error amplifier; connected to resistor divider from VOUT to set output voltage. |
| COMP (8) | Error amplifier output | Drives current-mode PWM comparator; connects to Type II/III compensation network for loop stability. |
| GND (9) | Signal ground | Reference for all analog circuitry; must be tied to thermal pad (Pin 11) and low-impedance PCB plane. |
| PH (10) | Switch node | Source of internal high-side MOSFET; connects to output inductor; requires low-inductance layout to minimize ringing. |
Key Features
| Feature | Design Value |
|---|---|
| Eco-mode™ Pulse Skipping | Reduces no-load input current to 116 μA by disabling switching cycles while maintaining regulation via output capacitor hold-up. |
| Integrated Boot Diode | Eliminates external bootstrap diode; reduces BOM count and layout area while enabling reliable 100% duty cycle operation. |
| Adjustable UVLO with Hysteresis | EN pin supports resistor-based UVLO threshold tuning (e.g., 7.7 V start / 6.7 V stop) for robust brown-out recovery. |
| Synchronization Capability | RT/CLK pin accepts external clock edges (300–2200 kHz) to eliminate beat frequencies in multi-rail systems. |
| Overvoltage Protection | PWRGD OV comparator disables high-side switch when VSENSE exceeds 107% VREF, limiting output overshoot during transients. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM5164QDDARQ1 | 42-V max input, 1-A output, 3.5-μA IQ, spread-spectrum EMI reduction | Better suited for automotive ASIL-B systems with stricter EMI requirements | Select LM5164QDDARQ1 when AEC-Q100 qualification and EMI compliance outweigh higher cost and lower current capability. |
| MP2451DT-LF-Z | 36-V max input, 0.6-A output, 250-μA IQ, fixed 2-MHz switching | Targeted at space-constrained consumer electronics with simpler design flow | Choose MP2451DT-LF-Z only for low-power applications where 0.6-A output suffices and 250-μA IQ is acceptable. |
Compared with LM5164QDDARQ1 and MP2451DT-LF-Z, the TPS54160DGQRG4 offers superior 60-V input tolerance, 1.5-A output, and lowest quiescent current (116 μA) among alternatives-making it optimal for high-voltage industrial and aftermarket designs requiring robustness and efficiency.

FAQ
What is the maximum input voltage rating for the TPS54160DGQRG4?
The TPS54160DGQRG4 has an absolute maximum input voltage rating of 65 V, with recommended operating range from 3.5 V to 60 V. This allows direct connection to 48-V industrial buses and tolerance of transient overvoltages such as load dump in automotive environments. Operation beyond 60 V risks permanent damage and violates TI's recommended conditions.
How does the TPS54160DGQRG4 achieve 116-μA quiescent current?
The TPS54160DGQRG4 achieves 116-μA quiescent current through Eco-mode™ pulse skipping: when load current drops below threshold, the device enters sleep mode, disabling switching and sustaining output solely via the output capacitor. Internal bias circuitry remains active but draws minimal current, verified across –40°C to 125°C junction temperatures per datasheet Section 7.5.
Can the TPS54160DGQRG4 synchronize to an external clock?
Yes, the TPS54160DGQRG4 can synchronize to an external clock via the RT/CLK pin. When pulled above 1.9 V, the internal amplifier disables and the pin becomes a high-impedance clock input accepting 300–2200 kHz signals with ≥40 ns pulse width. Synchronization eliminates beat frequencies in multi-converter systems and is confirmed in Section 8.3.4 and Figure 6 of the SLVSB56C datasheet.
What is the function of the SS/TR pin on the TPS54160DGQRG4?
The SS/TR pin on the TPS54160DGQRG4 serves dual functions: slow-start control via external capacitor (charged at 2 μA) to limit inrush current, and supply tracking via resistor divider for precise power sequencing. During faults, it discharges to ensure repeatable restart, as detailed in Section 8.1 and Terminal Functions Table in the SLVSB56C datasheet.
Does the TPS54160DGQRG4 require an external bootstrap diode?
No, the TPS54160DGQRG4 integrates the bootstrap diode, eliminating the need for an external component. A 0.1-μF X7R ceramic capacitor between BOOT and PH is required to supply gate drive voltage to the internal high-side MOSFET. This integration reduces BOM count and improves reliability, as stated in the Features section and Section 8.1 Overview of the SLVSB56C datasheet.
