Product details
Overview
TPS54060QDGQRQ1 from Texas Instruments is an automotive-grade 60-V, 0.5-A synchronous step-down DC/DC converter with integrated 200-mΩ high-side MOSFET, 0.8-V internal reference, and Eco-mode™ pulse-skipping for light-load efficiency. It operates from 3.5 V to 60 V input, delivers regulated output down to 0.8 V, and supports 100 kHz–2.5 MHz switching frequency-used in 12-V/24-V/48-V automotive power rails for infotainment and ADAS subsystems.
For engineers reviewing the TPS54060QDGQRQ1 datasheet, TPS54060QDGQRQ1 pinout, TPS54060QDGQRQ1 application, or TPS54060QDGQRQ1 equivalent, key selection criteria include its AEC-Q100 qualification, 116-μA quiescent current in Eco-mode, adjustable UVLO via EN pin, and MSOP-10 PowerPAD™ thermal performance for under-hood environments.
Technical Context
The TPS54060QDGQRQ1 implements peak-current-mode control with slope compensation to prevent subharmonic oscillation across 0–100% duty cycle. Its error amplifier features 97 μA/V transconductance (26 μA/V during slow start) and interfaces directly with external RC compensation on the COMP pin.
It integrates a PLL-based RT/CLK pin supporting both resistor-set frequency (100–2500 kHz) and external clock synchronization (300–2200 kHz), plus boot-UVLO protection that maintains high-side conduction until BOOT-PH drops below 2.1 V-enabling true low-dropout operation at up to 100% duty cycle.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.5 V to 60 V - supports wide automotive battery transients including cold-crank (≥4.5 V) and load-dump (≤60 V). |
| Output Current | 0.5 A continuous - sufficient for powering microcontrollers, sensors, and CAN transceivers in automotive ECUs. |
| Switching Frequency | 100 kHz to 2.5 MHz - enables optimization of inductor size and EMI filtering; programmable via RT resistor or external clock. |
| Quiescent Current | 116 μA in Eco-mode - extends battery life in always-on vehicle modules like telematics and alarm systems. |
| Shutdown Current | 1.3 μA - ensures negligible leakage during vehicle sleep mode, critical for meeting ISO 16750-2 quiescent current limits. |
| Voltage Reference | 0.8 V ±2% - sets minimum output voltage and defines feedback divider ratio; stable over –40°C to +150°C junction temperature. |
| High-Side RDS(on) | 200 mΩ @ 12 V VIN - reduces conduction loss and thermal stress in compact MSOP-10 PowerPAD™ package. |
Pinout & Package
TPS54060QDGQRQ1 is housed in a thermally enhanced 10-pin MSOP PowerPAD™ (DGQ) package with exposed thermal pad (Pin 11) requiring PCB solder connection to GND for optimal thermal performance (θJA = 62.5°C/W on standard board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BOOT (1) | Bootstrap gate drive supply node | Connects to 0.1-μF X7R/X5R ceramic capacitor between BOOT and PH; monitored by internal UVLO to disable high-side MOSFET if voltage falls below 2.1 V. |
| VIN (2) | Main input power supply | Accepts 3.5–60 V; includes internal 2.5-V UVLO threshold (adjustable via EN pin resistors) and 65-V absolute max rating. |
| EN (3) | Enable / UVLO adjustment input | Pulled up internally (0.9 μA); floating = enabled; threshold 0.9–1.55 V; used with two resistors to set custom input undervoltage lockout. |
| SS/TR (4) | Slow-start and tracking control | Charged by 2 μA current source; sets output ramp time via external capacitor; supports sequencing by coupling to another rail's feedback divider. |
| RT/CLK (5) | Frequency programming / sync input | Configurable as resistor-to-GND (100–2500 kHz) or high-impedance clock input (300–2200 kHz); includes PLL for jitter-free synchronization. |
| PWRGD (6) | Open-drain power-good indicator | Asserts low when VSENSE < 92% or > 109% of nominal; deasserts (high-Z) when within 94–107%, enabling system reset or sequencing logic. |
| VSENSE (7) | Inverting error amplifier input | Compares feedback voltage against 0.8-V reference or SS/TR voltage (whichever is lower); input bias current ≤10 μA. |
| COMP (8) | Error amplifier output / compensation node | Drives external RC network; transconductance 97 μA/V (26 μA/V during slow start); clamped at 500 mV in Eco-mode. |
| GND (9) | Analog and power ground reference | Common return for internal circuitry; must be connected to PCB ground plane with low-inductance path. |
| PH (10) | Power switch output node | Connects to external inductor and catch diode (or synchronous rectifier); carries high-frequency switching current and requires tight layout. |
Key Features
| Feature | Design Value |
|---|---|
| Eco-mode™ pulse-skipping | Reduces switching losses at light loads by entering burst-mode operation when peak inductor current falls below ~500 mA, maintaining 116-μA IQ. |
| Adjustable UVLO with hysteresis | EN pin allows precise setting of turn-on/off thresholds (e.g., 9 V ON / 7.5 V OFF) using two external resistors-critical for robust cold-crank behavior. |
| Integrated boot recharge diode | Eliminates need for external bootstrap diode, reducing BOM count and improving reliability in high-vibration automotive environments. |
| Power-good with OV/UV detection | PWRGD asserts low on overvoltage (>109% VREF) or undervoltage (<92% VREF), enabling fail-safe shutdown of downstream logic. |
| Thermal shutdown protection | Activates at 182°C junction temperature and holds off until safe cooldown, preventing permanent damage during overload or poor heatsinking. |

FAQ
What is the maximum input voltage rating for the TPS54060QDGQRQ1?
The TPS54060QDGQRQ1 has an absolute maximum input voltage rating of 65 V on the VIN pin, with recommended operating range from 3.5 V to 60 V. This allows reliable operation during automotive load-dump events per ISO 7637-2 Pulse 5a (up to 75 V for 100 ms), provided external TVS protection is implemented per design guidelines in the datasheet.
How does the Eco-mode™ function in the TPS54060QDGQRQ1 improve efficiency?
The TPS54060QDGQRQ1 enters Eco-mode™ when peak inductor current falls below ~500 mA, disabling switching pulses and reducing quiescent current to 116 μA. The COMP pin is clamped at 500 mV, and the device remains in this low-power state until output droop triggers a reactivation pulse-optimizing efficiency at light loads typical in automotive standby modes.
Can the TPS54060QDGQRQ1 synchronize to an external clock signal?
Yes-the RT/CLK pin of the TPS54060QDGQRQ1 supports external clock synchronization. When driven above 2.2 V, the internal oscillator disables and the pin becomes a high-impedance PLL input accepting 300–2200 kHz clock signals, enabling deterministic switching alignment with system clocks to reduce EMI beating in automotive ECUs.
What thermal considerations apply to the TPS54060QDGQRQ1 in MSOP-10 PowerPAD™ package?
The TPS54060QDGQRQ1 in DGQ package requires the exposed thermal pad (Pin 11) to be soldered to a PCB ground plane with ≥6 thermal vias (13 mil) for optimal performance. On a standard 2-layer board, θJA is 62.5°C/W; with proper layout, junction temperature stays within –40°C to +150°C under 0.5-A load at 85°C ambient.
Is the TPS54060QDGQRQ1 pin-compatible with other devices in the TPS54060-Q1 family?
Yes-the TPS54060QDGQRQ1 shares identical pinout and footprint with TPS54060QDRCRQ1 (SON-10) and higher-current variants like TPS54360QDGQRQ1 (MSOP-10), enabling layout reuse and scalable power design. However, current capability and thermal performance differ due to package construction and internal MOSFET sizing.
