Product details
Overview
TPS62293TDRVRQ1 from Texas Instruments is an AEC-Q100 qualified automotive synchronous step-down DC-DC converter delivering up to 1000 mA output current, operating from 2.3 V to 6.0 V input, with fixed 1.8 V output voltage, 2.25 MHz switching frequency, and ±1.5% output accuracy in PWM mode. It powers instrument clusters, ADAS front cameras, and infotainment head units.
For engineers reviewing the TPS62293TDRVRQ1 datasheet, TPS62293TDRVRQ1 pinout, TPS62293TDRVRQ1 application, or TPS62293TDRVRQ1 equivalent, key selection criteria include its 15 µA quiescent current in Power Save Mode, 100% duty cycle low-dropout capability, integrated high- and low-side MOSFETs with 240 mΩ/185 mΩ RDS(on), and 2-mm × 2-mm SON package for space-constrained automotive modules.
Technical Context
The TPS62293TDRVRQ1 implements a voltage-mode PWM controller with input voltage feedforward for fast line/load regulation and stable operation with small ceramic capacitors. Its dual-mode operation-fixed-frequency PWM (MODE = VIN) or automatic PFM/PWM transition (MODE = GND)-enables optimized efficiency across 0–1000 mA load range.
Internal circuitry includes undervoltage lockout (1.85 V falling threshold), thermal shutdown at 140°C, short-circuit protection via dual current-limit comparators, and dynamic voltage positioning (+1% nominal output during light loads) to suppress load-step undershoot/overshoot in safety-critical ADAS subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.3 V to 6.0 V - supports wide automotive battery range including cold-crank (≈6.0 V) and deep-discharge (≈2.3 V) conditions |
| Output Voltage | Fixed 1.8 V ±1.5% - eliminates external feedback resistors, reduces BOM count, ensures precise core logic rail for microcontrollers and sensors |
| Max Output Current | 1000 mA - sufficient for powering multiple SoC cores, image signal processors, or display timing controllers in cluster systems |
| Switching Frequency | 2.25 MHz (fixed) - enables use of compact 2.2 µH inductors and 10 µF ceramic output capacitors, minimizing solution footprint |
| Quiescent Current | 15 µA (Power Save Mode) - extends battery life in always-on vehicle modules such as parking assist or telematics wake-up circuits |
| RDS(on) High-Side | 240 mΩ (typical at 25°C) - minimizes conduction loss at 1 A, critical for thermal performance in sealed automotive enclosures |
| Package | 6-pin SON (2.0 mm × 2.0 mm × 0.8 mm) - thermally enhanced exposed pad design with 37.2°C/W junction-to-board resistance for reliable operation at 105°C ambient |
Pinout & Package
TPS62293TDRVRQ1 uses a thermally optimized 6-pin SON package (DRV) with an exposed PowerPAD for PCB-level heat dissipation. The package measures 2.0 mm × 2.0 mm × 0.8 mm and requires solder connection of the PowerPAD to a thermal pad on the PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW | Switch Node | Connects internal high-/low-side MOSFETs to external inductor; carries high di/dt switching current - must be routed with minimal loop area to reduce EMI |
| MODE | Mode Control Input | Pull to GND for automatic PFM/PWM transition; pull to VIN for forced fixed-frequency PWM - enables noise-sensitive or deterministic timing applications |
| FB | Feedback Input | Internally connected to fixed 1.8 V divider - no external resistors required; connect directly to output capacitor for stability |
| EN | Enable Input | Active-high logic control; drives low to enter <1 µA shutdown - used for power sequencing with other rails or MCU-controlled sleep/wake cycles |
| VIN | Input Power Supply | Accepts 2.3–6.0 V; requires local 10 µF ceramic decoupling close to pin to suppress high-frequency ripple and supply noise |
| GND | Ground Reference | Power ground return path; must be tied to PowerPAD and system ground plane with multiple vias for low-impedance thermal and electrical path |
Key Features
| Feature | Design Value |
|---|---|
| Automotive Qualification | AEC-Q100 Grade 1 (–40°C to +125°C TJ) - validated for under-hood and dashboard environments with full temperature cycling, HTOL, and ESD testing |
| Dynamic Voltage Positioning | +1% output offset in Power Save Mode - provides headroom to absorb sudden 100–500 mA load steps without violating 1.8 V ±5% core rail tolerance |
| 100% Duty Cycle Operation | Enables dropout <100 mV at 1 A - sustains regulated 1.8 V output down to VIN ≈ 1.9 V, maximizing usable battery capacity in 12 V systems |
| Integrated MOSFETs | High-side RDS(on) = 240 mΩ, low-side = 185 mΩ - eliminates external FETs and gate drivers, reducing component count and layout complexity |
| Thermal Shutdown | 140°C trip with 20°C hysteresis - protects against sustained overload or poor heatsinking while allowing recovery without system reset |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62290TDRVRQ1 | Adjustable output (0.6–VIN); requires external FB resistors; same 2.25 MHz, 1 A rating, and package | Suitable where multiple output voltages are needed on same PCB or firmware-configurable rails are required | Select when flexibility in output voltage outweighs BOM simplicity; adds two resistors and routing complexity |
| LMQ66430QRNXTQ1 | 3.0–36 V input; 3 A output; 2.1 MHz; integrated compensation; higher IQ (25 µA) | Targets higher-voltage automotive systems (e.g., body control modules) requiring wider VIN range and higher current | Choose only if input exceeds 6 V or output current >1 A is needed; larger 3.5 mm × 3.5 mm package increases footprint |
Compared with TPS62290TDRVRQ1, the TPS62293TDRVRQ1 saves board space and cost by eliminating FB resistors, while LMQ66430QRNXTQ1 trades off size and efficiency for broader input range and higher current - making TPS62293TDRVRQ1 optimal for compact, fixed 1.8 V applications in infotainment and ADAS edge nodes.

FAQ
What is the output voltage tolerance of the TPS62293TDRVRQ1 in PWM mode?
The TPS62293TDRVRQ1 has a fixed 1.8 V output with ±1.5% accuracy in PWM mode across temperature, line, and load conditions per the TI SLVSAI5B datasheet. This tight tolerance ensures reliable operation of 1.8 V I/O interfaces and core logic in automotive MCUs without requiring post-regulation LDOs.
Does the TPS62293TDRVRQ1 require external feedback resistors?
No, the TPS62293TDRVRQ1 does not require external feedback resistors because it integrates a precision resistor divider for its fixed 1.8 V output. The FB pin is internally connected and must be tied directly to the output capacitor - simplifying layout and reducing BOM count versus adjustable variants like TPS62290TDRVRQ1.
How does the MODE pin affect efficiency and noise performance of the TPS62293TDRVRQ1?
When the MODE pin is pulled low (GND), the TPS62293TDRVRQ1 enters Power Save Mode with automatic PFM/PWM transition, achieving up to 92% efficiency at 10 mA load and 15 µA quiescent current. When pulled high (VIN), it operates in fixed 2.25 MHz PWM mode - increasing light-load IQ to ~3.8 mA but enabling predictable EMI filtering for noise-sensitive analog circuits.
What thermal derating applies to the TPS62293TDRVRQ1 at 105°C ambient?
At 105°C ambient temperature, the TPS62293TDRVRQ1 maintains full 1000 mA output capability when properly mounted on a 4-layer PCB with the PowerPAD soldered to ≥2 cm² copper area. Its 37.2°C/W junction-to-board thermal resistance and 140°C thermal shutdown ensure safe operation without external heatsinks in typical automotive module enclosures.
Can the TPS62293TDRVRQ1 operate with input voltage below 2.3 V?
No, the TPS62293TDRVRQ1 has a minimum recommended input voltage of 2.3 V per TI's SLVSAI5B datasheet. Below this, undervoltage lockout activates at 1.85 V (falling), disabling regulation. For sub-2.3 V operation, consider TI's TPS62864 or alternative ultra-low-VIN buck converters - the TPS62293TDRVRQ1 is not specified or characterized for reliable function below 2.3 V.
