Product details
Overview
TPS61240IDRVRQ1 from Texas Instruments is an AEC-Q100 Grade 3 automotive-qualified synchronous step-up DC-DC converter delivering fixed 5 V output from 2.3 V–5.5 V input, supporting up to 450 mA output current with >90% efficiency at nominal conditions and 30 μA quiescent current in power-save mode. It serves as a compact, high-efficiency power rail generator for camera modules and display supplies in ADAS and infotainment systems.
For engineers reviewing the TPS61240IDRVRQ1 datasheet, TPS61240IDRVRQ1 pinout, TPS61240IDRVRQ1 application, or TPS61240IDRVRQ1 equivalent, key selection considerations include its 3.5-MHz quasi-constant on-time valley current-mode control, load disconnect during shutdown, –40°C to +85°C ambient operation, and WSON-6 (2 mm × 2 mm) package with exposed thermal pad.
Technical Context
The TPS61240IDRVRQ1 employs a quasi-constant on-time valley current-mode control architecture that enables fast line and load transient response while maintaining stable regulation across wide input voltage ranges. Its internal soft-start circuit limits inrush current, and the device transitions automatically between PFM (light load) and PWM (moderate/heavy load) modes to optimize efficiency.
During shutdown, the device presents high impedance at VOUT and fully disconnects the load from VIN via internal MOSFETs-eliminating battery drain without external components. The integrated 290 mΩ high-side and 250 mΩ low-side MOSFETs support efficient switching, and undervoltage lockout (2.1 V rising threshold) prevents operation under depleted battery conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5 V ±2% - ensures stable USB/MIPI/parallel interface rail compliance without external feedback resistors. |
| Input Voltage Range | 2.3 V to 5.5 V - supports single-cell Li-ion (2.7–4.2 V), Li-Polymer, and three-cell alkaline/NiMH batteries directly. |
| Max Output Current | 450 mA - sufficient to power image sensors, display drivers, and small microcontrollers in automotive ECUs. |
| Switching Frequency | 3.5 MHz typical - enables use of ultra-small 1 µH inductors and 0603 ceramic capacitors for <13 mm² total solution size. |
| Quiescent Current | 30 µA typical in PFM mode - extends battery life in always-on ADAS subsystems during standby. |
| Shutdown Current | 1.5 µA - minimizes parasitic drain when system is powered off, critical for automotive "key-off" requirements. |
| Operating Ambient Temp | –40°C to +85°C - meets AEC-Q100 Grade 3 specification for cabin-located electronics. |
Pinout & Package
TPS61240IDRVRQ1 is housed in a thermally enhanced 6-pin WSON package (2.00 mm × 2.00 mm) with exposed thermal pad requiring PCB land pattern connection for reliable thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | Power and IC ground reference | Common return path for all internal circuits and external components; must be low-impedance connection to PCB ground plane. |
| 2 VOUT | Regulated 5 V output supply | Delivers regulated power to load; high-impedance state during shutdown isolates downstream circuitry from battery. |
| 3 FB | Feedback input for output regulation | Internally connected to fixed resistor divider; requires direct connection to VOUT for accurate 5 V regulation. |
| 4 EN | Enable control input (active-high) | Pulls high to enable operation; pulls low to enter sub-2 µA shutdown with full load disconnect. |
| 5 L | Inductor switch node | Connects to one terminal of external boost inductor; carries high di/dt switching current and requires short, low-inductance trace routing. |
| 6 VIN | Input power supply | Accepts battery or pre-regulated input (2.3–5.5 V); includes undervoltage lockout and overvoltage protection circuitry. |
Key Features
| Feature | Design Value |
|---|---|
| Load Disconnect During Shutdown | Eliminates battery leakage paths by fully isolating VOUT from VIN using internal MOSFETs-no external ideal diode or load switch required. |
| Automatic PFM/PWM Mode Transition | Maintains >90% efficiency from 100 µA to 450 mA load without manual mode selection or external control signals. |
| Internal Soft Start (250 µs) | Prevents input voltage sag and inrush current spikes during power-up-critical for weak battery sources and shared input rails. |
| Thermal Shutdown with Hysteresis | Shuts down at 140°C junction temperature and resumes operation only after cooling by ≥20°C-prevents thermal runaway in enclosed ECU housings. |
| Only Three External Components | Requires just one 1 µH MLCC inductor and two ceramic capacitors (2.2 µF input, 4.7 µF output)-reduces BOM count and layout complexity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61230AQDRCRQ1 | Fixed 3.3 V output; 2.5 V–5.5 V input; 400 mA max; 2.5 MHz switching; same WSON-10 package | Not suitable for 5 V rail requirements; better for MCU core logic or I/O supply where 3.3 V is needed | Select only if system requires 3.3 V output and higher pin count allows WSON-10 footprint. |
| LM3671MF-5.0/NOPB | 5 V fixed output; 2.5 V–5.5 V input; 600 mA max; 2 MHz switching; SOT-23-5 package; non-automotive grade | Lacks AEC-Q100 qualification, thermal shutdown, and load disconnect-unsuitable for safety-critical ADAS deployment | Consider only for cost-sensitive non-automotive industrial or consumer applications requiring higher current but no functional safety compliance. |
Compared with TPS61240IDRVRQ1, the TPS61230AQDRCRQ1 provides lower output voltage and different package, limiting direct substitution; the LM3671MF-5.0/NOPB offers higher current but omits automotive qualification, load disconnect, and thermal protection-making it unsuitable for production ADAS hardware where reliability and safety are mandatory.

FAQ
What is the operating temperature range for TPS61240IDRVRQ1?
The TPS61240IDRVRQ1 is qualified to AEC-Q100 Grade 3 with an operating ambient temperature range of –40°C to +85°C. This rating is explicitly specified for the TPS61240IDRVRQ1 variant in the official datasheet and applies to continuous operation under recommended electrical conditions. Junction temperature must remain below 125°C, and thermal design must account for the 67.8°C/W junction-to-ambient thermal resistance of the WSON-6 package.
Does TPS61240IDRVRQ1 support true load disconnect during shutdown?
Yes, TPS61240IDRVRQ1 provides full load disconnect during shutdown: when EN is pulled low, both internal high-side and low-side MOSFETs turn off, presenting high impedance at the VOUT pin and electrically isolating the output from VIN. This feature eliminates battery leakage current-measured at <2.5 µA-and is confirmed in the datasheet's Description, Feature List, and Pin Functions sections.
What external components are required for basic operation of TPS61240IDRVRQ1?
TPS61240IDRVRQ1 requires only three external surface-mount components: a 1 µH shielded MLCC inductor between VIN and L pins, a 2.2 µF ceramic input capacitor (CIN) from VIN to GND, and a 4.7 µF ceramic output capacitor (COUT) from VOUT to GND. No external feedback resistors are needed-the 5 V output is internally fixed, and the FB pin connects directly to VOUT per the recommended schematic.
How does TPS61240IDRVRQ1 manage efficiency across varying load conditions?
TPS61240IDRVRQ1 uses automatic PFM/PWM mode transition: it operates in PWM mode above ~10 mA load for tight regulation and low ripple, then seamlessly shifts to PFM mode at lighter loads to maintain >85% efficiency down to 100 µA. Typical quiescent current is 30 µA in PFM mode, and shutdown current drops to 1.5 µA-enabling extended battery life in always-on ADAS subsystems.
Is TPS61240IDRVRQ1 compatible with Li-ion battery input sources?
Yes, TPS61240IDRVRQ1 is explicitly optimized for single-cell Li-ion and Li-Polymer batteries, supporting the full usable voltage range from 2.3 V (deep discharge) to 5.5 V (including charging transients). Its 2.1 V rising undervoltage lockout threshold prevents operation below safe battery levels, and its 6 V input overvoltage protection safeguards against charger-induced surges-both features validated in automotive-grade testing.
