Product details
Overview
TPS54160QDRCRQ1 from Texas Instruments is an automotive-grade 60-V input, 1.5-A synchronous step-down DC-DC converter with integrated 200-mΩ high-side MOSFET, 0.8-V internal reference, Eco-mode™ pulse-skipping control, and 116-μA quiescent current. It delivers regulated 3.3-V or 5-V outputs in automotive infotainment and industrial power supplies.
For engineers reviewing the TPS54160QDRCRQ1 datasheet, TPS54160QDRCRQ1 pinout, TPS54160QDRCRQ1 application, or TPS54160QDRCRQ1 equivalent, key selection criteria include its AEC-Q100 qualification, 100-kHz to 2.5-MHz adjustable switching frequency, RT/CLK synchronization capability, and PWRGD open-drain power-good output with ±8% threshold hysteresis.
Technical Context
The TPS54160QDRCRQ1 implements peak-current-mode control with slope compensation to prevent subharmonic oscillation across 0–100% duty cycle. Its transconductance error amplifier (97 μA/V) compares VSENSE against either the 0.8-V reference or SS/TR tracking voltage, enabling precise regulation and sequencing.
It integrates a bootstrap UVLO circuit that disables the high-side MOSFET when BOOT–PH falls below 2.1 V, enabling reliable 100% duty-cycle operation during dropout. The PLL-based RT/CLK pin supports both resistor-set frequency tuning (100–2500 kHz) and external clock synchronization with 100-μs lock-in time.

Pinout & Package
TPS54160QDRCRQ1 is housed in a 10-pin SON (DRC) PowerPAD™ package with exposed thermal pad for enhanced heat dissipation. Package dimensions: 3.0 mm × 3.0 mm × 0.9 mm, pitch = 0.5 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PH | High-side MOSFET source | Connects to inductor node; carries full switching current and must be routed with low-inductance layout |
| GND | Power and signal ground | Reference for all analog circuits; must be tied directly to exposed thermal pad for thermal and EMI performance |
| COMP | Error amplifier output | Interface for Type II/III compensation network; sets loop stability and transient response |
| VSENSE | Inverting input of error amplifier | Monitors output via resistor divider; 0.8-V threshold enables adjustable output from 0.8 V upward |
| BOOT | Bootstrap capacitor connection | Supplies gate drive for high-side MOSFET; requires 0.1-μF X7R/X5R ceramic capacitor to PH |
| VIN | Main input supply | Accepts 3.5–60 V; includes internal UVLO (2.5 V default) and reverse-polarity protection diode path |
| EN | Enable and UVLO adjust | Pull below 1.25 V to disable; external resistors set custom undervoltage lockout threshold |
| SS/TR | Slow-start and tracking input | Controls output ramp rate via capacitor; supports power sequencing by connecting to upstream rail |
| PWRGD | Open-drain power-good output | Asserts low when VOUT is outside 92–109% window; requires external pullup resistor |
| RT/CLK | Frequency setting/synchronization | Configurable as resistor-to-ground (100–2500 kHz) or external clock input (300–2200 kHz) |

FAQ
What is the maximum input voltage rating for the TPS54160QDRCRQ1?
The TPS54160QDRCRQ1 has an absolute maximum VIN 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 load-dump transients up to 60 V in automotive applications without external clamping.
Does the TPS54160QDRCRQ1 require an external bootstrap diode?
No, the TPS54160QDRCRQ1 integrates the bootstrap diode internally. Only a 0.1-μF ceramic capacitor between BOOT and PH pins is required to provide gate-drive voltage for the high-side MOSFET, simplifying layout and reducing component count.
How does the Eco-mode™ operation improve light-load efficiency in the TPS54160QDRCRQ1?
The TPS54160QDRCRQ1 enters Eco-mode™ when output current drops below ~18 mA (dependent on inductor value), skipping switching pulses to reduce gate-drive and switching losses. This achieves 116-μA quiescent current and >85% efficiency at 10-mA load, critical for always-on automotive modules.
Can the TPS54160QDRCRQ1 synchronize to an external clock signal?
Yes, the RT/CLK pin supports synchronization: when pulled above 2.2 V, it switches from resistor-set mode to high-impedance clock input, accepting external 300–2200 kHz signals with 100-μs PLL lock time-enabling EMI reduction through frequency alignment in multi-converter systems.
What is the function of the SS/TR pin on the TPS54160QDRCRQ1?
The SS/TR pin controls output voltage ramp rate during startup (slow-start) or matches output to another rail (tracking). A capacitor sets rise time; a resistor divider enables sequencing. During faults, it discharges to ensure repeatable restart-critical for reliable power-up in automotive ECUs.
