Product details
Overview
TPS62262TDRVRQ1 from Texas Instruments is an AEC-Q100 qualified automotive-grade synchronous step-down DC-DC converter delivering up to 600 mA output current with fixed 2.5 V output voltage, 2.25 MHz switching frequency, and 15 μA typical quiescent current in Power Save Mode. It operates from 2 V to 6 V input-supporting single Li-ion, multi-cell alkaline, or 3.3/5 V rails-and is used in infotainment power supplies and ADAS camera modules.
For engineers reviewing the TPS62262TDRVRQ1 datasheet, TPS62262TDRVRQ1 pinout, TPS62262TDRVRQ1 application, or TPS62262TDRVRQ1 equivalent, key selection criteria include automotive temperature range (–40°C to +105°C), 2×2 mm SON package footprint, voltage positioning for load transients, and MODE-pin controllable PFM/PWM mode transition.
Technical Context
The TPS62262TDRVRQ1 uses voltage-mode control with input voltage feed-forward for fast line/load regulation and supports automatic transition between PWM and Power Save Mode (PFM) based on load current. Its internal high-side and low-side MOSFETs feature 240–480 mΩ and 185–380 mΩ RDS(on), respectively, enabling efficient operation across its 2–6 V input range.
Dynamic voltage positioning raises the regulated output by +1% in PFM mode to reduce load-step undershoot, while 100% duty-cycle operation extends battery runtime near dropout. The MODE pin forces fixed-frequency PWM (for EMI-sensitive designs) or enables automatic PFM entry below ~10 mA load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.5 V ±1.5% in PWM mode; ensures stable core supply for automotive microcontrollers without external feedback resistors. |
| Max Output Current | 600 mA at VIN ≥ 2.5 V; sufficient to power dual-core ARM Cortex-M7 SoCs or image signal processors in ADAS cameras. |
| Switching Frequency | 2.25 MHz (±12.5%); allows use of compact 2.2 μH inductors and 0603-size ceramic capacitors for <1 mm solution height. |
| Quiescent Current | 15 μA typical in PFM mode; extends battery life in always-on vehicle telematics modules during sleep states. |
| Operating Temp Range | –40°C to +105°C ambient; meets AEC-Q100 Grade 2 requirements for under-hood and cabin-mounted electronics. |
| Input Voltage Range | 2 V to 6 V; supports full discharge curve of single Li-ion (2.7–4.2 V) plus headroom for cold-cranking dips and boost-derived rails. |
| Shutdown Current | <1 μA at EN = GND; enables zero-power state for intrusion detection sensors and keyless entry receivers. |
Pinout & Package
TPS62262TDRVRQ1 is housed in a thermally enhanced 2×2×0.8 mm SON-6 package with exposed thermal pad (DRV suffix), optimized for high-density automotive PCB layouts and thermal dissipation in confined enclosures.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW | Switch node | Connects to inductor; carries high di/dt switching current-requires tight layout and Kelvin connection to minimize EMI and voltage spikes. |
| MODE | Mode control input | Pull to GND for auto PFM/PWM transition; pull to VIN for forced fixed-frequency PWM-critical for noise-sensitive RF or audio subsystems. |
| FB | Feedback input | Internally connected to 2.5 V divider; not accessible in fixed-output variants-eliminates resistor placement error and saves board space. |
| EN | Enable input | Active-high logic; enables precise power sequencing with other rails and supports system-level wake-up via microcontroller GPIO. |
| VIN | Power input | Accepts 2–6 V; includes undervoltage lockout (1.85 V falling threshold) to prevent brownout operation and battery over-discharge. |
| GND | Power ground | Reference for all internal circuits; must be tied directly to exposed thermal pad for optimal thermal performance and noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 2 certified (–40°C to +105°C), with production test coverage for safety-critical vehicle systems. |
| Voltage positioning | +1% output offset in PFM mode reduces load-step undershoot by >50 mV-enabling tighter output tolerance without larger bulk capacitance. |
| 100% duty cycle operation | Maintains regulation down to VIN ≈ VOUT + IOUT × (RDS(on)_HS + DCR_L); extends usable battery range by up to 15 minutes in portable diagnostic tools. |
| Soft start | 250 μs VOUT ramp time (5%→95%) limits inrush current to <300 mA-prevents input rail collapse during cold-start sequences. |
| Low-noise PWM mode | Fixed 2.25 MHz frequency enables predictable EMI filtering with small LC components-essential for compliance with CISPR 25 Class 5. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62263TDRVRQ1 | Fixed 2.5 V output, same package and specs-but rated for –40°C to +105°C (same as TPS62262TDRVRQ1). | Identical automotive temperature grade; differs only in top-side marking (OFG vs OFF) and minor production lot traceability. | Select when requiring identical electrical performance with alternate TI manufacturing lot sourcing. |
| TPS6286218MRTERQ1 | 2.5 V fixed output, 3 MHz switching, 1.2 A capability, 1.5 μA IQ, but in 1.5×1.5 mm WSON package. | Higher current and lower IQ, but requires PCB redesign due to smaller footprint and different pinout (no MODE pin). | Choose for next-gen designs needing higher efficiency and density-only after validating thermal performance and EMI behavior. |
Compared with TPS62262TDRVRQ1, TPS62263TDRVRQ1 offers identical functionality and qualification, making it a direct manufacturing alternative; TPS6286218MRTERQ1 delivers superior specs but demands layout changes and requalification due to architectural differences.

FAQ
What is the output voltage tolerance of the TPS62262TDRVRQ1 in PWM mode?
The TPS62262TDRVRQ1 has a fixed 2.5 V output with ±1.5% accuracy in PWM mode across temperature, line, and load conditions per the datasheet's Electrical Characteristics table. This tolerance ensures reliable operation of 2.5 V-tolerant microcontrollers and interface ICs without additional regulation stages.
Does the TPS62262TDRVRQ1 require external feedback resistors?
No, the TPS62262TDRVRQ1 does not require external feedback resistors because it integrates a precision internal resistor divider for its fixed 2.5 V output. The FB pin is internally connected and not user-accessible-reducing BOM count and layout complexity versus adjustable variants like TPS62260TDRVRQ1.
How does the MODE pin affect efficiency and noise performance of the TPS62262TDRVRQ1?
When the MODE pin is pulled low (GND), the TPS62262TDRVRQ1 enters Power Save Mode and automatically transitions to PFM at light loads-achieving 15 μA IQ and high efficiency but with variable frequency. When pulled high (VIN), it forces fixed 2.25 MHz PWM mode, improving EMI predictability at the cost of higher light-load current (~3.8 mA).
What is the maximum continuous output current the TPS62262TDRVRQ1 can deliver at 105°C ambient?
At TA = 105°C, the TPS62262TDRVRQ1 maintains up to 600 mA output current when properly heatsinked via its exposed thermal pad and using recommended PCB copper area (≥250 mm²). Derating is not required within its specified operating junction temperature limit of 125°C.
Is the TPS62262TDRVRQ1 pin-compatible with other devices in the TPS6226x-Q1 family?
Yes, all TPS6226x-Q1 devices-including TPS62260TDRVRQ1, TPS62261TDRVRQ1, TPS62262TDRVRQ1, and TPS62263TDRVRQ1-share identical 2×2 mm SON-6 pinout, package dimensions, and terminal functions. Only the output voltage and top-side marking differ between variants.
