Product details
Overview
TPS54061QDRBTQ1 from Texas Instruments is a wide-input, 60-V, 200-mA synchronous step-down DC–DC converter with integrated high-side and low-side MOSFETs, 90-µA non-switching quiescent current, and adjustable 50-kHz to 1.1-MHz switching frequency. It delivers regulated bias voltage in automotive infotainment power rails where input transients reach 60 V.
For engineers reviewing the TPS54061QDRBTQ1 datasheet, TPS54061QDRBTQ1 pinout, TPS54061QDRBTQ1 application, or TPS54061QDRBTQ1 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, diode-emulation light-load efficiency mode, 0.8 V ±1% reference accuracy, and thermal shutdown at 176°C - all validated for under-hood automotive use cases.
Technical Context
The TPS54061QDRBTQ1 implements peak-current-mode control with internal slope compensation to prevent subharmonic oscillation across duty cycles up to 98%. Its transconductance error amplifier (108 µA/V) drives the COMP pin for external Type II/III compensation, while the RT/CLK pin supports both resistor-programmed frequency and PLL-based synchronization to external clocks from 300 kHz to 1.1 MHz.
It integrates boot recharge diode and monitors BOOT-PH voltage with dedicated UVLO (2.9 V), enabling reliable high-duty-cycle operation. The device features cycle-by-cycle current limiting (250–500 mA threshold), frequency foldback during overloads, and internal slow-start (2.36 ms typical) controlled by a reference DAC system - all without requiring external timing capacitors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.7 V to 60 V - supports cold-crank and load-dump conditions in 12 V/24 V automotive systems |
| Output Current | 200 mA continuous - sufficient for MCU core logic, CAN transceivers, and sensor interface rails |
| Quiescent Current | 90 µA (non-switching) - enables always-on standby power without battery drain |
| Switching Frequency | 50 kHz to 1.1 MHz - adjustable via RT/CLK resistor or synchronizable to external clock for EMI reduction |
| Voltage Reference | 0.8 V ±1% - enables precise output regulation down to 0.8 V with 1% resistor dividers |
| Thermal Shutdown | 176°C - protects against sustained overload or poor PCB thermal design |
| Operating Junction Temp | –40°C to 150°C - meets AEC-Q100 Grade 1 ambient requirement (–40°C to +125°C) |
Pinout & Package
TPS54061QDRBTQ1 uses a thermally enhanced 3-mm × 3-mm, 8-pin SON (DRB) package with exposed thermal pad (Pin 9) that must be soldered to GND for proper thermal performance and electrical stability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BOOT | Bootstrap supply node | Drives gate of internal high-side MOSFET; requires external 0.1-µF ceramic capacitor to PH |
| VIN | Main power input | Accepts 4.7–60 V; powers internal circuitry and high-side driver; includes 4.5-V UVLO |
| EN | Enable control with UVLO adjustment | Pull below 1.18 V to disable; internal 1.2-µA pullup enables floating operation; supports resistor-divider UVLO tuning |
| RT/CLK | Frequency programming/synchronization | Resistor-to-GND sets frequency (50–1100 kHz); external clock >300 kHz synchronizes falling edge to PH rising edge |
| VSENSE | Feedback input | Inverting input of error amplifier; connects to resistor divider from VOUT to set output voltage per VREF = 0.8 V |
| COMP | Compensation node | Error amplifier output; connects to external RC network for loop stability (Type II/III) |
| GND | Power and signal ground | Reference for all analog circuits; must connect to thermal pad and system ground plane |
| PH | Switch node | Source of high-side MOSFET / drain of low-side MOSFET; connects to external inductor and bootstrap capacitor |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM5164QDGSRQ1 | 4.5–65 V input, 300 mA, 1.5-A peak switch current; higher current capability but larger 10-pin WSON package | Better suited for 300-mA loads like radar modules; lacks diode emulation, resulting in lower light-load efficiency | Select when higher output current or wider VIN range (65 V) is required; verify loop compensation due to different gm error amp |
| MPQ4420AGL-AEC1-Z | 3.3–60 V input, 2-A continuous, 3.5-A peak; uses external MOSFETs, requiring more board space and gate drive design | Targets higher-power domains (e.g., ADAS domain controllers); not qualified for AEC-Q100 Grade 1 junction temp | Choose only if >200 mA output is needed; requires additional components and layout effort versus TPS54061QDRBTQ1's integrated solution |
Compared with LM5164QDGSRQ1 and MPQ4420AGL-AEC1-Z, the TPS54061QDRBTQ1 offers optimal integration and ultra-low IQ for sub-200-mA automotive bias rails, while maintaining AEC-Q100 Grade 1 compliance and minimal footprint - making it ideal for space-constrained, always-on subsystems.

FAQ
What is the minimum input voltage required for TPS54061QDRBTQ1 to start switching?
The TPS54061QDRBTQ1 has an internal undervoltage lockout (UVLO) threshold of 4.5 V on the VIN pin. When VIN rises above this level and the EN pin voltage exceeds 1.23 V, the device initiates soft-start. This ensures reliable startup after cold-crank events in 12 V automotive systems. The TPS54061QDRBTQ1 will not switch below 4.5 V unless the EN pin is externally biased to override default behavior.
Can TPS54061QDRBTQ1 operate with ceramic output capacitors?
Yes, the TPS54061QDRBTQ1 is explicitly designed to be stable with low-ESR ceramic output capacitors - eliminating the need for bulk aluminum electrolytic capacitors. Its control loop and internal compensation architecture accommodate ceramic capacitance values as low as 10 µF, improving reliability and temperature performance across –40°C to +125°C ambient. The TPS54061QDRBTQ1 datasheet provides recommended type and value ranges for optimal transient response.
How does the diode emulation mode improve efficiency in TPS54061QDRBTQ1?
The TPS54061QDRBTQ1 enters diode emulation mode when inductor current reaches zero, turning off the low-side MOSFET to prevent reverse current flow. This eliminates switching losses associated with synchronous rectification at light loads (<10 mA), increasing efficiency by up to 15% compared to forced PWM operation. The TPS54061QDRBTQ1 automatically transitions between modes based on load - no external control is required.
What is the purpose of the RT/CLK pin in TPS54061QDRBTQ1?
The RT/CLK pin serves dual functions: (1) as a resistor-programmable oscillator input (50–1100 kHz) when pulled to GND via timing resistor, and (2) as a high-impedance synchronization input when driven by an external clock signal (300–1100 kHz). The TPS54061QDRBTQ1 detects rising voltage above 1.8 V to auto-switch from RT mode to PLL mode, aligning PH rising edges to CLK falling edges - critical for EMI-sensitive automotive designs.
Is TPS54061QDRBTQ1 compatible with standard PCB assembly processes for automotive-grade manufacturing?
Yes, the TPS54061QDRBTQ1 uses a RoHS-compliant, lead-free 3-mm × 3-mm SON package (DRB) qualified for reflow soldering per J-STD-020. Its exposed thermal pad requires Type II solder paste and controlled thermal profile to ensure void-free attachment to GND. The TPS54061QDRBTQ1 meets AEC-Q100 stress test requirements including HTOL, TC, and UHAST - confirming suitability for automated SMT lines in Tier-1 automotive production environments.
