Product details
Overview
TPS62260IDRVRQ1 from Texas Instruments is an automotive-grade, adjustable-output 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, operates at 2.25 MHz fixed frequency, supports Power Save Mode (PFM) with 15 μA quiescent current, and features voltage positioning (+1%) for load transient suppression in mobile phones and portable media players.
For engineers reviewing the TPS62260IDRVRQ1 datasheet, TPS62260IDRVRQ1 pinout, TPS62260IDRVRQ1 application, or TPS62260IDRVRQ1 equivalent, key selection criteria include its AEC-Q100 qualification, 2×2 mm SON-6 package footprint, adjustable output range (0.6 V to VIN), 1.5% PWM-mode output accuracy, and MODE-pin controllable PFM/PWM transition behavior.
Technical Context
The TPS62260IDRVRQ1 uses voltage-mode control with input voltage feed-forward for fast line/load regulation and employs internal high-side (240–480 mΩ) and low-side (185–380 mΩ) MOSFETs. Its 2.25-MHz oscillator enables use of small 2.2 μH inductors and 0603 ceramic capacitors, supporting <1-mm solution height.
Power Save Mode activates automatically when MODE = GND, reducing switching frequency and quiescent current to ~15 μA while maintaining +1% voltage positioning; forced PWM mode (MODE = VIN) ensures fixed-frequency operation for noise-sensitive applications, with output accuracy ±1.5% over 0–600 mA load range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2 V to 6 V - supports single Li-ion (2.7–4.2 V), two/three alkaline cells, and 3.3/5 V rails without external regulators. |
| Output Current | Up to 600 mA - sufficient for core logic, DSP, and RF subsystems in portable automotive infotainment units. |
| Switching Frequency | 2.25 MHz (±12.5%) - enables compact filter design with 2.2 μH inductor and 10 μF output capacitor. |
| Quiescent Current | 15 μA typical in PFM mode - extends battery runtime during standby in always-on telematics modules. |
| Output Accuracy | ±1.5% in PWM mode - ensures stable core voltage for 1.8 V I/O domains in automotive microcontrollers. |
| Shutdown Current | <1 μA - meets ultra-low leakage requirements for ignition-off power domains. |
| Thermal Shutdown | 140°C with 20°C hysteresis - protects against sustained overload in sealed automotive enclosures. |
Pinout & Package
The TPS62260IDRVRQ1 is housed in a thermally enhanced 2×2×0.8 mm SON-6 package with exposed thermal pad (DRV variant), enabling efficient heat dissipation in space-constrained automotive PCB layouts.
| 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. |
| MODE | Mode Control Input | Pull to GND for automatic PFM/PWM transition; pull to VIN for forced fixed-frequency PWM - enables dynamic noise/power trade-off. |
| FB | Feedback Input | Adjustable output setpoint via external resistor divider; open for fixed-output variants - supports precise 1.8 V rail tuning. |
| EN | Enable Input | Active-high logic control; drives low to enter shutdown (<1 μA IQ) - used for power sequencing with other system rails. |
| VIN | Power Input | Primary supply input (2–6 V); must be decoupled with ≥4.7 μF ceramic capacitor close to pin. |
| GND | Power Ground | System ground reference; connects to exposed thermal pad - critical for thermal performance and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Qualified | Rated for automotive ambient temperature (–40°C to +85°C) and vibration/shock environments per ISO 16750. |
| Voltage Positioning | +1% output offset in PFM mode reduces load-step undershoot by providing headroom before regulation recovery. |
| 100% Duty Cycle Operation | Enables dropout as low as IO × (RDS(on) + DCRinductor) - maximizes usable battery voltage range in end-of-discharge conditions. |
| Soft Start | 250 μs ramp time (5%→95%) limits inrush current into bulk capacitance - prevents input rail sag during power-up. |
| Undervoltage Lockout | 1.85 V falling threshold prevents erratic operation during brownout - protects battery from deep discharge. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62261TDRVRQ1 | Fixed 1.8 V output; identical package, pinout, and electrical specs except FB pin internally tied to divider. | No external feedback resistors needed; eliminates BOM cost but removes output adjustability. | Select when 1.8 V rail is fixed and board space is constrained - no layout change required. |
| TPS62260TDRVRQ1 | Same adjustable architecture but rated for –40°C to +105°C junction temperature (vs. +85°C for TPS62260IDRVRQ1). | Suitable for under-hood applications requiring extended temperature operation. | Choose for engine-control proximity or high-ambient environments where junction temp may exceed 85°C. |
Compared with TPS62261TDRVRQ1, the TPS62260IDRVRQ1 offers design flexibility via external feedback but requires two resistors; versus TPS62260TDRVRQ1, it trades extended temperature rating for lower cost in cabin-mounted modules.

FAQ
What is the operating temperature range for the TPS62260IDRVRQ1?
The TPS62260IDRVRQ1 is qualified for automotive ambient operation from –40°C to +85°C, with junction temperature rated up to +125°C. This range aligns with AEC-Q100 Grade 3 requirements and supports deployment in instrument clusters, center consoles, and body control modules where ambient temperatures remain below 85°C.
How does the MODE pin affect TPS62260IDRVRQ1 operation?
The MODE pin on the TPS62260IDRVRQ1 selects between Power Save Mode (MODE = GND) and forced PWM mode (MODE = VIN). In PFM mode, the TPS62260IDRVRQ1 reduces switching frequency and quiescent current to ~15 μA; in forced PWM, it maintains 2.25 MHz operation regardless of load, improving noise predictability at the cost of light-load efficiency.
Can the TPS62260IDRVRQ1 support 100% duty cycle operation?
Yes, the TPS62260IDRVRQ1 supports 100% duty cycle operation when input voltage approaches the output voltage, minimizing dropout to IO × (RDS(on) + DCRinductor). This feature extends usable battery life in Li-ion systems by allowing full discharge down to ~2.3 V while maintaining regulation - confirmed in the datasheet's recommended operating conditions table.
What is the output voltage accuracy specification for TPS62260IDRVRQ1 in PWM mode?
In PWM mode, the TPS62260IDRVRQ1 guarantees output voltage accuracy of ±1.5% over temperature and line/load conditions (2.5 V ≤ VIN ≤ 6 V, 0 mA ≤ IOUT ≤ 600 mA). This tolerance applies to the feedback reference voltage (600 mV) and is critical for powering 1.8 V I/O domains in automotive MCUs where voltage margin is tightly constrained.
Is the TPS62260IDRVRQ1 pin-compatible with other devices in the TPS6226x-Q1 family?
Yes, all TPS6226x-Q1 devices including TPS62260IDRVRQ1, TPS62261TDRVRQ1, TPS62262TDRVRQ1, and TPS62263TDRVRQ1 share identical 2×2 mm SON-6 pinout and footprint. This allows direct substitution between adjustable and fixed-output variants, or between temperature grades, without PCB redesign - verified in TI's package drawing DRV0006A.
