Product details
Overview
TPS62067AQDSGRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive synchronous step-down DC/DC converter delivering up to 2 A output current with 3-MHz fixed-frequency PWM operation, ±1.5% output voltage accuracy in PWM mode, and open-drain power-good (PG) output - designed for 5-V or 3.3-V rail conversion in ADAS camera modules.
For engineers reviewing the TPS62067AQDSGRQ1 datasheet, TPS62067AQDSGRQ1 pinout, TPS62067AQDSGRQ1 application, or TPS62067AQDSGRQ1 equivalent, key selection criteria include its forced-PWM-only operation (no MODE pin), integrated output capacitor discharge, 18-µA quiescent current, and 2 × 2-mm WSON-8 package with exposed thermal pad for thermal reliability in space-constrained automotive PCBs.
Technical Context
The TPS62067AQDSGRQ1 implements a voltage-mode control architecture with input-voltage feedforward, enabling fast line/load regulation using only a 1-µH inductor and 10-µF ceramic output capacitor. Its 3-MHz oscillator includes clock dithering (6 ns typical) to suppress RF harmonics, and it integrates undervoltage lockout (1.78 V falling, 1.95 V rising) and thermal shutdown (150°C, 10°C hysteresis).
Unlike the TPS62067-Q1 (auto PFM/PWM with MODE/PG shared pin), the TPS62067AQDSGRQ1 fixes PWM operation and dedicates Pin 6 exclusively to PG - eliminating mode-selection ambiguity. It supports 100% duty-cycle low-dropout operation and dynamic voltage positioning (1% above nominal VOUT) during light-load transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 2.9 V to 6 V - compatible with automotive 3.3-V and 5-V system rails without pre-regulation |
| Output Current | 2 A continuous - sufficient for powering dual-core SoCs or image signal processors in ADAS ECUs |
| Switching Frequency | 3 MHz (typical) - enables ultra-small passive components and avoids AM/FM radio bands |
| Quiescent Current | 18 µA - minimizes standby power loss in always-on vehicle subsystems |
| Output Accuracy | ±1.5% in PWM mode - ensures stable core voltage for safety-critical microcontrollers |
| Power-Good Threshold | 95% of VFB (rising), 90% (falling) - provides precise sequencing margin for downstream logic |
| Thermal Shutdown | 150°C with 10°C hysteresis - protects against sustained overload in enclosed enclosures |
Pinout & Package
TPS62067AQDSGRQ1 uses a thermally enhanced 2.00 mm × 2.00 mm × 0.75-mm WSON-8 package (DSG) with exposed thermal pad soldered to PCB ground for optimal heat dissipation in automotive under-hood environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 PGND | Power Ground | Return path for high-current output stage; must be connected to low-impedance ground plane |
| 2 SW | Switch Node | Drives external 1-µH inductor; requires tight layout to minimize EMI and switching losses |
| 3 AGND | Analog Ground | Reference for feedback and control circuitry; isolated from PGND at single-point connection |
| 4 FB | Feedback Input | Senses output voltage via resistor divider; internal 0.6-V reference sets VOUT = 0.6 × (1 + R1/R2) |
| 5 EN | Enable Input | Active-high logic; pulls low to enter 5-µA shutdown with automatic output capacitor discharge |
| 6 PG | Power-Good Output | Open-drain signal indicating regulated VOUT; requires external pullup (e.g., 100-kΩ to AVIN) |
| 7 AVIN | Analog Supply | Powers internal control circuitry; must be decoupled with 10-µF ceramic capacitor near pin |
| 8 PVIN | Power Supply Input | High-current input rail; connects directly to bulk input capacitor and shares ground with PGND |
Key Features
| Feature | Design Value |
|---|---|
| Forced PWM Operation | No PFM mode - eliminates low-frequency output ripple and simplifies EMI filtering for noise-sensitive imaging sensors |
| Integrated Output Discharge | Internal 75–1450-Ω discharge resistor activated during shutdown - prevents floating VOUT and enables safe hot-plug sequencing |
| Dynamic Voltage Positioning | Maintains VOUT 1% above nominal during light load - reduces undershoot on sudden load steps common in radar processing bursts |
| 100% Duty-Cycle Mode | Enables dropout < 200 mV at full load - extends usable battery range in 12-V systems with buck-boost front-end |
| Automotive Qualification | AEC-Q100 Grade 1 (–40°C to +125°C TJ), HBM ±2500 V, CDM ±750 V - validated for engine bay and cockpit deployment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62067QDSGRQ1 | Shares same package and pinout but uses MODE/PG dual-function pin; auto-transitions between PFM/PWM based on load | Higher light-load efficiency but introduces low-frequency ripple unsuitable for imaging or audio circuits | Select when system prioritizes >90% efficiency at 10-mA loads over EMI control |
| TPS628502QWNRQ1 | 6-V input, SOT583 package, higher 95% peak efficiency, integrated soft-start ramp control | Larger solution size due to 2.5-mm × 2.5-mm footprint; lacks dedicated PG pin (uses FLAG instead) | Select when upgrading to higher VIN range or needing programmable soft-start for multi-rail sequencing |
Compared with TPS62067AQDSGRQ1, the TPS62067QDSGRQ1 offers better light-load efficiency but sacrifices EMI predictability, while the TPS628502QWNRQ1 improves power density and efficiency at the cost of PG functionality and increased layout complexity.

FAQ
What distinguishes TPS62067AQDSGRQ1 from TPS62067QDSGRQ1?
The TPS62067AQDSGRQ1 operates exclusively in forced PWM mode with a dedicated PG pin (Pin 6), whereas the TPS62067QDSGRQ1 uses Pin 6 as a MODE/PG multiplexed terminal that defaults to auto PFM/PWM transition. This makes TPS62067AQDSGRQ1 ideal for noise-sensitive applications like camera ISPs where consistent 3-MHz switching is mandatory, while TPS62067QDSGRQ1 suits systems prioritizing ultra-low IQ at light loads. Both share identical WSON-8 packaging and thermal performance.
Does TPS62067AQDSGRQ1 support adjustable output voltage?
Yes, TPS62067AQDSGRQ1 supports adjustable output voltage via an external resistor divider connected to the FB pin. With an internal 0.6-V reference, VOUT is calculated as VOUT = 0.6 × (1 + R1/R2). The device is commonly configured for 1.2 V, 1.8 V, or 3.3 V outputs - all verified in TI's typical application circuits. Fixed-output variants are not offered; design flexibility is built into the base TPS62067AQDSGRQ1 silicon.
How does the output capacitor discharge function work in TPS62067AQDSGRQ1?
When EN is pulled low, TPS62067AQDSGRQ1 activates an internal discharge resistor (75–1450 Ω, depending on VIN and VOUT) between the SW node and PGND, safely bleeding charge from the output capacitor within milliseconds. This prevents residual voltage from interfering with downstream logic reset sequencing or causing latch-up during hot-restart. The function requires VIN > 1 V to remain active and is disabled during normal operation.
What thermal performance can be expected from TPS62067AQDSGRQ1 in a 4-layer PCB?
In a standard 4-layer automotive PCB with 1-in² 2-oz copper thermal pad connected to internal ground planes, TPS62067AQDSGRQ1 achieves a junction-to-board thermal resistance (RθJB) of 34.6°C/W. At 2-A load and 4.2-V input, typical power dissipation is ~250 mW, resulting in ~8.7°C junction rise above ambient - well within the –40°C to +125°C AEC-Q100 Grade 1 rating. No external heatsink is required under these conditions.
Is TPS62067AQDSGRQ1 qualified for functional safety applications?
Yes, TPS62067AQDSGRQ1 is functional safety-capable per ISO 26262, with documentation available from Texas Instruments to support ASIL-B system-level development. It includes diagnostic features such as power-good monitoring, thermal shutdown with hysteresis, undervoltage lockout, and short-circuit foldback protection - all independently verified under AEC-Q100 stress testing. Safety manuals and FMEDA reports are provided in the TI product folder.
