Product details
Overview
TPS62260TDDCRQ1 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–VIN), operates at 2.25 MHz fixed frequency, and supports Power Save Mode with voltage positioning for portable media players and low-power DSP supplies.
For engineers reviewing the TPS62260TDDCRQ1 datasheet, TPS62260TDDCRQ1 pinout, TPS62260TDDCRQ1 application, or TPS62260TDDCRQ1 equivalent, key selection criteria include its AEC-Q100 Grade 2 qualification (–40°C to 105°C), 15 μA typical quiescent current in PFM mode, 2×2 mm SON-6 package, and MODE-pin controllable transition between PWM and Power Save Mode.
Technical Context
The TPS62260TDDCRQ1 uses voltage-mode control with input voltage feed-forward for fast line/load regulation and supports discontinuous conduction mode (DCM) during light-load transitions. Its internal synchronous rectification employs high-side and low-side MOSFETs with RDS(on) of 240–480 mΩ and 185–380 mΩ respectively.
Power Save Mode activates when the MODE pin is pulled low, enabling pulse-frequency modulation (PFM) with dynamic voltage positioning (+1% VOUT) and automatic PWM-to-PFM transition at light loads. Forced PWM operation is enabled by pulling MODE high, fixing switching at 2.25 MHz for noise-sensitive applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2 V to 6 V - supports single Li-ion cells (2.7–4.2 V), extended-range Li-ion (2–4.5 V), and dual/triple alkaline batteries. |
| Output Current | Up to 600 mA - sufficient for powering baseband processors, RF transceivers, and display drivers in automotive infotainment modules. |
| Switching Frequency | 2.25 MHz (±12.5%) - enables use of small 2.2 μH inductors and 0603-size ceramic capacitors for compact PCB layouts. |
| Quiescent Current | 15 μA (typ) in PFM mode - extends battery runtime in always-on automotive telematics and sensor nodes. |
| Output Voltage Accuracy | ±1.5% in PWM mode - ensures stable core voltage for microcontrollers and FPGAs without external trimming. |
| Shutdown Current | <1 μA - meets automotive low-power standby requirements for ECU wake-up circuits. |
| Thermal Shutdown | 140°C with 20°C hysteresis - protects against thermal runaway in sealed automotive enclosures. |
Pinout & Package
The TPS62260TDDCRQ1 is housed in a thermally enhanced 2×2×0.8 mm SON-6 package with exposed thermal pad (DRV variant). This ultra-compact footprint supports <1-mm solution height and enables high-density automotive PCB designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW | Switch node | Connects to external inductor; carries high di/dt switching current - requires tight layout and ground plane beneath. |
| MODE | Mode control input | Pull low for automatic PWM/PFM transition; pull high for forced fixed-frequency PWM - enables system-level noise management. |
| FB | Feedback input | Connects to resistor divider for adjustable output; open for fixed-output variants - sets regulation point with ±1.5% accuracy in PWM mode. |
| EN | Enable input | Active-high logic; drives low to enter shutdown (<1 μA IQ) - supports power sequencing with other rails in multi-rail ECUs. |
| VIN | Power input | Accepts 2–6 V supply; includes undervoltage lockout (1.85 V falling threshold) - prevents brownout operation and battery over-discharge. |
| GND | Ground reference | Power and signal return; ties to exposed thermal pad - critical for thermal performance and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 2 (–40°C to +105°C ambient) - certified for under-hood and dashboard-mounted electronics. |
| Voltage positioning | +1% VOUT offset in Power Save Mode - reduces load-step undershoot/overshoot in camera modules and radar sensors. |
| 100% duty cycle operation | Enables dropout as low as IOUT × (RDS(on) + DCRL) - maximizes usable battery range in GPS trackers and telematics units. |
| Soft start | 250 μs VOUT ramp time (5% to 95%) - limits inrush current into downstream LDOs and memory devices. |
| Thermal protection | 140°C shutdown with 20°C hysteresis - prevents permanent damage during transient overload in engine control units. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62261TDDCRQ1 | Fixed 1.8 V output; identical package, pinout, and specs otherwise. | Eliminates external feedback resistors - simplifies BOM and layout for fixed-voltage designs. | Select when output voltage is fixed and board space is constrained; no requalification needed for same thermal/mechanical interface. |
| TPS62231DQCR | Non-automotive grade (–40°C to 85°C); 3-MHz switching; lower IQ (12 μA). | Lacks AEC-Q100 qualification and 105°C rating - unsuitable for under-hood or dashboard mounting. | Consider only for non-automotive industrial or consumer applications where cost and size are prioritized over automotive compliance. |
Compared with TPS62261TDDCRQ1, the TPS62260TDDCRQ1 offers design flexibility via adjustable output but requires two external resistors; compared with TPS62231DQCR, it provides guaranteed automotive reliability at the cost of slightly higher quiescent current and lower switching frequency.

FAQ
What is the maximum output current capability of the TPS62260TDDCRQ1?
The TPS62260TDDCRQ1 delivers up to 600 mA output current when VIN ≥ 2.5 V. At lower input voltages (2.3–2.5 V), maximum output current is reduced to 300 mA, and at 2–2.3 V, it is limited to 150 mA due to internal current-limit thresholds and MOSFET RDS(on) constraints. These values are specified in the Electrical Characteristics table and validated across –40°C to 105°C.
How does the MODE pin affect operation of the TPS62260TDDCRQ1?
The MODE pin on the TPS62260TDDCRQ1 selects between two operating modes: pulling MODE low enables automatic Power Save Mode (PFM at light loads, PWM at heavy loads) with voltage positioning; pulling MODE high forces fixed-frequency 2.25 MHz PWM operation regardless of load. This allows system designers to trade off efficiency versus EMI performance based on real-time application needs.
Is the TPS62260TDDCRQ1 qualified for automotive applications?
Yes, the TPS62260TDDCRQ1 is AEC-Q100 Grade 2 qualified for automotive use, with guaranteed operation from –40°C to +105°C ambient temperature. It includes automotive-specific features including undervoltage lockout (1.85 V), thermal shutdown (140°C), and robust ESD protection (2000 V HBM), making it suitable for infotainment, telematics, and body electronics applications.
What package type and dimensions does the TPS62260TDDCRQ1 use?
The TPS62260TDDCRQ1 uses a 2×2×0.8 mm SON-6 package (DRVT suffix) with an exposed thermal pad. This thermally enhanced, lead-free package supports <1-mm solution height and is optimized for high-density automotive PCB layouts. Pin assignments match the DRV package drawing in the official TI datasheet SLVSA16C.
Can the TPS62260TDDCRQ1 operate with 100% duty cycle, and what is its benefit?
Yes, the TPS62260TDDCRQ1 supports 100% duty cycle operation when VIN approaches VOUT, maintaining regulation down to VIN = VOUT + IOUT × (RDS(on) + DCRL). This feature maximizes usable battery voltage range in automotive applications - for example, sustaining 1.8 V output from a discharging Li-ion cell down to ~2.1 V, extending operational time in GPS loggers and emergency call modules.
