Product details
Overview
TPS62263TDRVRQ1 from Texas Instruments is an automotive-grade, synchronous step-down DC-DC converter optimized for Li-ion battery-powered systems. It delivers up to 600 mA output current from a 2–6 V input, features adjustable output voltage (0.6 V to VIN), operates at 2.25 MHz fixed frequency, and supports Power Save Mode with voltage positioning for portable infotainment and ADAS power rails.
For engineers reviewing the TPS62263TDRVRQ1 datasheet, TPS62263TDRVRQ1 pinout, TPS62263TDRVRQ1 application, or TPS62263TDRVRQ1 equivalent, key selection considerations include its AEC-Q100 Grade 2 qualification (–40°C to +105°C), 15 μA quiescent current in PFM mode, 100% duty cycle low-dropout operation, and compatibility with small 2.2 μH inductors and 0603-size ceramic capacitors in space-constrained automotive modules.
Technical Context
The TPS62263TDRVRQ1 employs voltage-mode control with input voltage feed-forward for fast line/load regulation and stable operation with minimal external components. Its dual-mode architecture automatically transitions between fixed-frequency PWM (2.25 MHz) and pulse-frequency modulation (PFM) based on load current, enabling high efficiency across 10 μA–600 mA.
Dynamic voltage positioning raises the regulated output by +1% in PFM mode to suppress load-step undershoot, while the MODE pin allows forced PWM operation for noise-sensitive applications. Internal MOSFETs feature RDS(on) of 240 mΩ (high-side) and 185 mΩ (low-side) at 3.6 V, supporting efficient 100% duty cycle operation near dropout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2 V to 6 V - supports single-cell Li-ion (2.7–4.2 V), extended-range Li-ion (2–4.5 V), and 3.3/5 V rails. |
| Output Current | Up to 600 mA - sufficient for powering DSPs, microcontrollers, and sensors in automotive body electronics. |
| Switching Frequency | 2.25 MHz (fixed) - enables use of compact 2.2 μH inductors and avoids AM radio band interference. |
| Quiescent Current | 15 μA (typ, PFM mode) - extends battery life in always-on vehicle modules like telematics and door controllers. |
| Output Voltage Range | 0.6 V to VIN (adjustable) - configurable via external resistor divider for custom rail requirements (e.g., 1.2 V, 1.8 V, 3.3 V). |
| Operating Temperature | –40°C to +105°C - meets AEC-Q100 Grade 2 for under-hood and cabin-mounted ECUs. |
| Efficiency Peak | ≥92% at 3.6 VIN/1.8 VOUT/100 mA - reduces thermal stress in sealed enclosures. |
Pinout & Package
The TPS62263TDRVRQ1 is housed in a thermally enhanced 2 mm × 2 mm × 0.8 mm SON-6 package with exposed thermal pad (DRV suffix), suitable for high-density automotive PCB layouts requiring <1 mm solution height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW | Switch Node | Connects internal high/low-side MOSFETs to external inductor; requires low-inductance layout to minimize EMI and switching losses. |
| MODE | Mode Control Input | Pull to GND for automatic PFM/PWM transition; pull to VIN for forced fixed-frequency PWM-critical for EMI filtering in camera modules. |
| FB | Feedback Input | Connects to resistor divider for adjustable output; open for fixed-output variants-enables precise rail tuning without BOM changes. |
| EN | Enable Input | Active-high logic control; ties to upstream regulator or MCU GPIO for power sequencing in multi-rail systems. |
| VIN | Power Input | Accepts 2–6 V supply; bypass with 4.7 μF 0603 ceramic capacitor close to pin to suppress input ripple. |
| GND | Power Ground | Reference for all internal circuits; must be connected to exposed thermal pad for optimal thermal performance and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive Qualification | AEC-Q100 Grade 2 (–40°C to +105°C ambient) - validated for engine bay and dashboard electronics. |
| Voltage Positioning | +1% output offset in PFM mode - reduces transient undershoot during sudden load steps (e.g., radar burst activation). |
| 100% Duty Cycle Operation | Supports VIN as low as VOUT + IOUT × (RDS(on) + DCR) - maximizes battery runtime down to 2.3 V in GPS trackers. |
| Soft Start | 250 μs ramp time (5% to 95%) - prevents inrush current damage to input capacitors and upstream FETs. |
| Low-Noise PWM Mode | Fixed 2.25 MHz switching with MODE = VIN - simplifies EMI filter design for camera and audio subsystems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62262TDRVRQ1 | Fixed 1.2 V output; no FB pin required; identical package and thermal specs. | Eliminates external resistor divider but lacks output flexibility for multi-rail designs. | Select when system requires only 1.2 V and board space is constrained-reduces BOM count by two resistors. |
| LMQ66430QRNXTQ1 | 3.0 V to 36 V input; 3 A output; integrated compensation; higher quiescent current (25 μA). | Targets 12 V automotive systems directly; overqualified for low-voltage battery rails. | Choose for high-input-voltage applications (e.g., front-end power distribution) where 2–6 V range is insufficient. |
Compared with TPS62262TDRVRQ1, the TPS62263TDRVRQ1 offers design flexibility via adjustable output but requires two external resistors; versus LMQ66430QRNXTQ1, it provides superior light-load efficiency and smaller solution size for Li-ion–fed sub-systems, though with lower input voltage capability.

FAQ
What is the maximum output current capability of the TPS62263TDRVRQ1?
The TPS62263TDRVRQ1 delivers up to 600 mA continuous output current when VIN ≥ 2.5 V. At lower input voltages (2.0–2.3 V), the maximum supported output current reduces to 300 mA, and at 2.0 V it is limited to 150 mA due to internal current-limit thresholds and MOSFET RDS(on) constraints. These limits ensure reliable operation across the full automotive input range.
How does the MODE pin affect TPS62263TDRVRQ1 operation in automotive systems?
The MODE pin on the TPS62263TDRVRQ1 selects between Power Save Mode (MODE = GND) and forced PWM mode (MODE = VIN). In automotive applications, GND configuration enables automatic PFM/PWM transition for peak efficiency during variable loads (e.g., infotainment standby vs. active), while VIN configuration locks 2.25 MHz operation to simplify EMI filtering in camera or audio subsystems sensitive to frequency variation.
Is the TPS62263TDRVRQ1 compatible with standard 0603-size external components?
Yes, the TPS62263TDRVRQ1 is fully compatible with 0603-size ceramic capacitors (e.g., 4.7 μF input, 10 μF output) and 2.2 μH shielded inductors such as the Murata LPS3015 series. This compatibility enables a total solution height under 1 mm, meeting stringent mechanical constraints in modern automotive modules like digital clusters and smart sensors.
What is the purpose of voltage positioning in the TPS62263TDRVRQ1, and how does it improve system performance?
Voltage positioning in the TPS62263TDRVRQ1 raises the regulated output by +1% during Power Save Mode to provide headroom against load-step undershoot. When a sudden current demand occurs (e.g., radar pulse), the elevated rail delays the onset of voltage droop, allowing the control loop time to respond-improving transient stability without requiring larger output capacitance or secondary LDOs in safety-critical ADAS subsystems.
Does the TPS62263TDRVRQ1 support 100% duty cycle operation, and under what conditions?
Yes, the TPS62263TDRVRQ1 supports true 100% duty cycle operation when VIN approaches VOUT, enabling minimum dropout behavior critical for battery longevity. This occurs automatically when the input voltage falls within ~200 mV above the regulated output (e.g., 1.8 V out at 2.0 V in), calculated as VINmin = VOUT + IOUT × (RDS(on)max + DCRL). It sustains regulation down to 2.0 V input at light loads, maximizing usable battery capacity.
