Product details
Overview
TPS54160DGQ 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, adjustable 100 kHz–2.5 MHz switching frequency via RT/CLK pin, and open-drain PWRGD output monitoring VSENSE within 94%–107% of nominal. It enables compact, high-efficiency power supplies in automotive infotainment and industrial 24-V systems.
For engineers reviewing the TPS54160DGQ datasheet, TPS54160DGQ pinout, TPS54160DGQ application, or TPS54160DGQ equivalent, key selection considerations include its 3.5–60-V input range, 0.8-V internal reference, MSOP-10 package with PowerPAD™ thermal pad, UVLO adjustability via EN pin, and compatibility with WEBBENCH® design tools.
Technical Context
The TPS54160DGQ implements constant-frequency peak current-mode control with slope compensation to prevent subharmonic oscillation across duty cycles. Its integrated boot regulator supports 100% duty cycle operation as long as BOOT–PH voltage exceeds 2.1 V.
It features an error amplifier with 26 μ℧ transconductance during slow start and 97 μ℧ typical under normal operation, plus a PLL-enabled RT/CLK pin supporting both resistor-set frequency (100–2500 kHz) and external clock synchronization (300–2200 kHz).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.5 V to 60 V - supports wide-input industrial and automotive rails without pre-regulation. |
| Output Current | 1.5 A continuous - delivers regulated power to microcontrollers, sensors, and interface ICs. |
| Switching Frequency | 100 kHz to 2.5 MHz - enables optimization of inductor size and efficiency trade-offs. |
| Quiescent Current | 116 μA - minimizes standby power loss in battery-backed or always-on systems. |
| Shutdown Current | 1.3 μA - ensures ultra-low leakage during system sleep or disable states. |
| Reference Voltage | 0.8 V ±1.6% - sets precise output regulation threshold for adjustable VOUT designs. |
| High-Side RDS(on) | 200 mΩ at VIN = 12 V - reduces conduction loss and improves full-load efficiency. |
Pinout & Package
TPS54160DGQ is housed in a thermally enhanced MSOP-10 package with exposed thermal pad (Pin 11), requiring PCB solder connection to GND for reliable thermal performance and electrical stability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BOOT (1) | Bootstrap supply node | Connects to PH via 0.1-μF ceramic capacitor; gate drive voltage source for high-side MOSFET. |
| VIN (2) | Main input supply | Accepts 3.5–60 V; powers internal circuitry and high-side switch; includes 2.5-V UVLO threshold. |
| EN (3) | Enable control input | Pull below 1.25 V to disable; internal pull-up allows floating-enable; supports adjustable UVLO with resistive divider. |
| SS/TR (4) | Slow-start/tracking control | Capacitor sets soft-start time; external voltage enables supply sequencing or tracking of another rail. |
| RT/CLK (5) | Frequency configuration | Resistor-to-GND sets fSW; externally driven clock synchronizes switching to system timing source. |
| PWRGD (6) | Power-good status output | Open-drain signal asserts low when VSENSE falls below 94% or rises above 107% of nominal. |
| VSENSE (7) | Feedback input | Inverting input of transconductance error amplifier; compares output voltage against 0.8-V reference. |
| COMP (8) | Error amplifier output | Drives current-mode PWM comparator; connects to external compensation network for loop stability. |
| GND (9) | Ground reference | Common return for analog and power circuits; must be connected to thermal pad for thermal integrity. |
| PH (10) | Power switch node | Switching node connecting internal MOSFET source to inductor; requires low-inductance layout. |
Key Features
| Feature | Design Value |
|---|---|
| Eco-mode™ Pulse Skipping | Reduces no-load input current to 116 μA while maintaining regulation-critical for energy-sensitive applications. |
| Adjustable UVLO with Hysteresis | EN pin allows user-defined input undervoltage lockout using two resistors-enables custom brown-out protection. |
| Integrated Boot Diode | Eliminates external bootstrap diode-reduces BOM count and improves reliability in space-constrained layouts. |
| Thermal Shutdown & Frequency Foldback | Protects against overload by reducing fSW and disabling switching above 182°C-prevents thermal runaway. |
| UV/OV Power-Good Detection | PWRGD pin provides fault indication for both under- and overvoltage conditions-supports system-level safety monitoring. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM5164QDRCRQ1 | 42-V max input, 1-A output, spread-spectrum EMI reduction, no integrated boot diode | Better EMI compliance for automotive ADAS; lower current rating limits use in high-power infotainment | Select when EMI certification is critical and 1-A output suffices; requires external bootstrap diode |
| TPS54260DGQ | Same family, 2.5-A output, identical pinout and feature set except higher current capability | Direct upgrade path for designs needing >1.5 A; shares same layout and compensation network | Choose when future-proofing for higher load or margin expansion is required; drop-in compatible |
Compared with LM5164QDRCRQ1 and TPS54260DGQ, the TPS54160DGQ offers optimal balance of 60-V input tolerance, 1.5-A capability, and ultra-low quiescent current-making it ideal for cost- and space-sensitive 24-V industrial and automotive accessory designs where EMI spread spectrum is not mandated.

FAQ
What is the maximum input voltage rating for the TPS54160DGQ?
The TPS54160DGQ supports an absolute maximum input voltage of 65 V, with recommended continuous operation up to 60 V. Its 3.5–60 V input range makes it suitable for harsh environments like automotive battery systems and industrial 48-V buses, where transient spikes must be tolerated without damage or regulation loss.
Does the TPS54160DGQ require an external bootstrap diode?
No, the TPS54160DGQ integrates a boot recharge diode, eliminating the need for an external component. This simplifies layout, reduces BOM count, and improves reliability-especially in high-vibration environments such as automotive applications where solder joint integrity is critical.
How does the Eco-mode™ function in the TPS54160DGQ improve efficiency?
Eco-mode™ enables pulse-skipping operation at light loads, reducing switching activity and gate drive losses. The TPS54160DGQ achieves just 116 μA operating quiescent current in this mode-extending battery life in always-on or intermittently active systems without sacrificing regulation accuracy or transient response.
Can the TPS54160DGQ synchronize to an external clock signal?
Yes, the RT/CLK pin supports synchronization: when driven with a clock signal exceeding the PLL upper threshold (1.9–2.2 V), the TPS54160DGQ disables its internal oscillator and locks to the external clock edge. This enables deterministic timing in multi-rail systems and reduces EMI through frequency alignment.
What thermal considerations apply to the TPS54160DGQ in MSOP-10 (DGQ) package?
The TPS54160DGQ in DGQ package has θJA = 62.5°C/W on a standard board. Its exposed thermal pad (Pin 11) must be soldered to a GND copper pour for effective heat dissipation. Without proper thermal pad connection, junction temperature rise may exceed safe limits under 1.5-A load, triggering thermal shutdown.
