Product details
Overview
TPS62290TDRVRQ1 from Texas Instruments is an AEC-Q100 qualified automotive-grade 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 2.25-MHz switching frequency and ±1.5% output voltage accuracy in PWM mode. It powers critical subsystems in instrument clusters and front cameras where compact size and high efficiency across light-to-heavy loads are essential.
For engineers reviewing the TPS62290TDRVRQ1 datasheet, TPS62290TDRVRQ1 pinout, TPS62290TDRVRQ1 application, or TPS62290TDRVRQ1 equivalent, key selection considerations include its 2-mm × 2-mm SON package, Power Save Mode enabling 15-µA quiescent current at light loads, dynamic voltage positioning for load-step stability, 100% duty-cycle low-dropout operation, and MODE pin-controlled PFM/PWM mode selection.
Technical Context
The TPS62290TDRVRQ1 implements a voltage-mode PWM controller with input voltage feedforward for fast line/load regulation and uses internal high-side (240–480 mΩ) and low-side (185–380 mΩ) MOSFETs. Its 2.25-MHz fixed-frequency operation enables small external components-2.2 µH inductor and 10 µF ceramic output capacitor-while maintaining stable regulation across –40°C to +105°C ambient.
In Power Save Mode (MODE = GND), it transitions automatically to PFM with +1% dynamic voltage positioning and typical 15-µA quiescent current; forced PWM mode (MODE = VIN) eliminates frequency variation for noise-sensitive applications. Thermal shutdown triggers at 140°C with 20°C hysteresis, and undervoltage lockout activates below 1.85 V (falling).
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 (≥2.3 V) and post-regulation rails. |
| Output Current | 1000 mA - sufficient for powering SoCs, image sensors, and display drivers in ADAS and infotainment systems. |
| Switching Frequency | 2.25 MHz (fixed) - enables use of tiny 2.2 µH inductors and 10 µF ceramic capacitors for minimal PCB footprint. |
| Quiescent Current | 15 µA (typical, PFM mode) - extends battery life in always-on vehicle modules without compromising wake-up responsiveness. |
| Output Voltage Accuracy | ±1.5% (PWM mode) - ensures reliable logic-level compliance for 1.8 V, 3.3 V, or adjustable rails under full temperature and load range. |
| Thermal Shutdown | 140°C (typical) with 20°C hysteresis - protects against sustained overload or poor heatsinking in sealed automotive enclosures. |
| Package | 6-pin 2.0 mm × 2.0 mm × 0.8 mm SON - thermally enhanced surface-mount package with exposed PowerPAD for efficient PCB heat dissipation. |
Pinout & Package
TPS62290TDRVRQ1 is housed in a thermally optimized 6-pin SON (Small Outline No-lead) package measuring 2.0 mm × 2.0 mm × 0.8 mm, featuring an exposed PowerPAD that must be soldered to a thermal pad on the PCB for proper junction-to-board thermal resistance (RθJB = 37.2°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - SW | Switch node | Connects internally to high- and low-side MOSFETs; external inductor ties here - requires tight layout to minimize EMI and switching losses. |
| 2 - 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 designs. |
| 3 - FB | Feedback input | Senses output voltage via external resistor divider (or direct connection for fixed-VOUT versions); sets regulation point using 0.6 V internal reference. |
| 4 - EN | Enable input | Active-high logic control; pulling low disables converter and reduces supply current to <1 µA - used for power sequencing and system-level sleep control. |
| 5 - VIN | Power input | Accepts 2.3–6.0 V; requires local 10 µF ceramic decoupling close to pin to suppress high-frequency ripple and ensure stability. |
| 6 - GND | Ground reference | Primary signal and power return; must be connected to PCB ground plane and tied electrically to exposed PowerPAD for thermal and electrical integrity. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 1 (–40°C to +125°C TJ) - validated for under-hood and cabin electronics with full reliability testing. |
| Dynamic voltage positioning | +1% output offset in PFM mode - reduces undershoot/overshoot during rapid load transients (e.g., camera sensor burst mode). |
| 100% duty-cycle operation | Enables dropout as low as VOUT + IOUT × (RDS(on) + RL) - maximizes runtime from partially discharged 12 V or 48 V battery systems. |
| Integrated MOSFETs | High-side RDS(on) = 240–480 mΩ, low-side = 185–380 mΩ - eliminates external FETs and gate drivers, reducing BOM count and layout complexity. |
| Soft-start timing | 250 µs ramp (5% → 95% VOUT) - limits inrush current into output capacitance, preventing input rail collapse during cold boot. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62293TDRVRQ1 | Fixed 3.3 V output (vs. adjustable 0.6–6 V on TPS62290TDRVRQ1); identical package, pinout, and functional modes. | Eliminates external feedback resistors but lacks flexibility for multi-rail systems requiring 1.8 V or custom voltages. | Select when 3.3 V is the sole required output and BOM simplification is prioritized over design reuse. |
| LM61480QRNXTQ1 | Higher 8-A capability, 2.1-MHz switching, and integrated compensation; larger 3 mm × 4 mm VQFN package with different pinout. | Targets higher-power domains (e.g., radar processors); not pin-compatible and requires PCB redesign. | Choose only when scaling beyond 1 A is needed - not a drop-in replacement, but a higher-capacity alternative for next-gen platforms. |
Compared with TPS62290TDRVRQ1, TPS62293TDRVRQ1 offers identical form-factor and functionality with factory-set 3.3 V output, while LM61480QRNXTQ1 provides greater current headroom at the cost of board area and layout rework - making TPS62290TDRVRQ1 optimal for space-constrained 1-A automotive rails requiring voltage flexibility.

FAQ
What is the maximum output current capability of the TPS62290TDRVRQ1?
The TPS62290TDRVRQ1 delivers up to 1000 mA continuous output current when operating within its recommended conditions (VIN = 2.7–6.0 V, TA ≤ +105°C). At lower input voltages (2.3–2.5 V), output current is derated to 300 mA due to internal MOSFET RDS(on) and thermal limits. This rating assumes proper PCB thermal design with the PowerPAD soldered to a copper thermal pad.
How does the MODE pin affect operation of the TPS62290TDRVRQ1?
The MODE pin on the TPS62290TDRVRQ1 selects between two operational modes: pulling MODE to GND enables automatic Power Save Mode (PFM at light loads, PWM at heavy loads), while pulling MODE to VIN forces fixed-frequency PWM operation across all load conditions. This allows designers to prioritize efficiency (GND) or EMI predictability (VIN) based on system requirements.
Can the TPS62290TDRVRQ1 support 1.8 V output, and how is it configured?
Yes, the TPS62290TDRVRQ1 supports 1.8 V output via an external resistor divider connected to the FB pin. Using the internal 0.6 V reference, R1 = 360 kΩ and R2 = 180 kΩ yields VOUT = 0.6 V × (1 + 360k/180k) = 1.8 V. The datasheet confirms this configuration in the TPS62290DRV schematic and specifies C1 = 22 pF feedforward capacitor for optimal transient response.
What thermal protection features does the TPS62290TDRVRQ1 include?
The TPS62290TDRVRQ1 incorporates thermal shutdown that disables both MOSFETs when junction temperature exceeds 140°C (typical), with 20°C hysteresis to prevent oscillation. It also features undervoltage lockout (UVLO) that disables operation below 1.85 V (falling) to protect batteries and prevent erratic behavior. These protections are fully specified in the Electrical Characteristics table and operate independently of external circuitry.
Is the TPS62290TDRVRQ1 pin-compatible with other devices in the TPS6229x-Q1 family?
Yes, the TPS62290TDRVRQ1 shares identical 6-pin SON (DRV) package, pinout, and footprint with all members of the TPS6229x-Q1 family-including TPS62293TDRVRQ1 and TPS62291TDRVRQ1. This enables direct substitution for different output voltage options (adjustable vs. fixed 3.3 V or 5 V) without PCB changes, provided external feedback components are adjusted or removed accordingly.
