Product details
Overview
TPS62260TDRVRQ1 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 dynamic voltage positioning for load-step response in portable infotainment and ADAS power rails.
For engineers reviewing the TPS62260TDRVRQ1 datasheet, TPS62260TDRVRQ1 pinout, TPS62260TDRVRQ1 application, or TPS62260TDRVRQ1 equivalent, this page provides verified technical context, validated pin functions, confirmed automotive qualification (AEC-Q100 Grade 2), real-world efficiency curves across input voltages, and two rigorously cross-checked alternative parts for design flexibility.
Technical Context
The TPS62260TDRVRQ1 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 compact 2.2 μH inductor and 10 μF ceramic capacitor designs while maintaining stable operation down to 150 mA at 2 V input.
In Power Save Mode (MODE = GND), it enters discontinuous conduction mode with PFM pulses timed to maintain ±1% output voltage positioning above nominal-reducing light-load ripple and improving transient headroom. Forced PWM mode (MODE = VIN) disables automatic mode transition and ensures fixed-frequency operation for EMI-sensitive applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2 V to 6 V - supports full Li-ion battery discharge (2.7 V–4.2 V) plus alkaline/3.3 V/5 V rails without external regulators. |
| Output Current | Up to 600 mA - sufficient for powering ARM Cortex-A/M cores, LPDDR memory I/O, or camera sensor ISPs in automotive modules. |
| Switching Frequency | 2.25 MHz (±12.5%) - enables use of sub-3 mm × 3 mm inductors and avoids AM radio band interference. |
| Quiescent Current | 15 μA (typ, PFM, no switching) - extends battery runtime in always-on vehicle telematics or remote keyless entry receivers. |
| Feedback Reference | 600 mV - allows adjustable output from 0.6 V to VIN via external resistor divider; supports 1.2 V, 1.8 V, 2.5 V, 3.3 V configurations. |
| Shutdown Current | <1 μA - meets automotive "off-mode" leakage requirements for body control modules and gateway ECUs. |
| Operating Temp Range | –40°C to +105°C - qualified per AEC-Q100 Grade 2 for under-hood and dashboard-mounted electronics. |
Pinout & Package
TPS62260TDRVRQ1 is housed in a thermally enhanced 2 mm × 2 mm × 0.8 mm 6-pin SON (DRV) package with exposed thermal pad for PCB heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW | Switch node | Connects to inductor; carries high di/dt switching current; requires tight layout to minimize EMI and voltage spikes. |
| MODE | Mode selection control | GND enables automatic PFM/PWM transition; VIN forces fixed-frequency PWM-critical for noise-sensitive audio or RF subsystems. |
| FB | Feedback input | Monitors output via external resistor divider; open for fixed-output variants; must be terminated with RC filter if used for stability tuning. |
| EN | Enable input | Active-high logic; supports power sequencing with other rails; pulls to GND for <1 μA shutdown state. |
| VIN | Power input | Accepts 2–6 V; requires local 4.7 μF ceramic decoupling; shares thermal pad with GND for low-impedance return path. |
| GND | Ground reference | Power and signal ground; connects to exposed thermal pad; must be solidly stitched to inner-layer ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Dynamic Voltage Positioning | Maintains output 1% above nominal during light loads-reduces undershoot on sudden 100 mA → 500 mA load steps by >80 mV in typical layouts. |
| 100% Duty Cycle Operation | Enables dropout as low as 120 mV at 600 mA (VIN ≈ VOUT + IO × RDS(on))-extends usable battery range down to 2.3 V for 1.8 V rail. |
| Soft Start | Ramps output from 5% to 95% of target in 250 μs-limits inrush into 10 μF output caps and prevents brownout in shared input rails. |
| Undervoltage Lockout | Activates at 1.85 V falling threshold-prevents erratic startup and protects Li-ion cells from deep discharge below 2.5 V. |
| Thermal Shutdown | Triggers at 140°C junction temperature with 20°C hysteresis-protects against sustained overload or poor heatsinking in sealed enclosures. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62261TDRVRQ1 | Fixed 1.8 V output; identical pinout, package, and electrical specs except FB pin internally tied to divider. | No external feedback resistors required; eliminates BOM cost and layout area but forfeits output voltage flexibility. | Select when 1.8 V is fixed system requirement and board space is constrained-no redesign needed beyond removing R1/R2. |
| TPS62865DRLR | Higher 3 A output, 4 MHz switching, smaller 1.5 mm × 2.0 mm WSON, but requires external compensation and lacks voltage positioning. | Supports higher-power SoCs (e.g., TI Jacinto 7); not drop-in due to different pinout, loop compensation, and MODE behavior. | Choose for next-gen platforms needing >1 A capability and tighter EMI control-requires full schematic/layout revision. |
Compared with TPS62261TDRVRQ1, the TPS62260TDRVRQ1 offers design flexibility via adjustable output but adds two resistors; versus TPS62865DRLR, it trades peak current and frequency for proven AEC-Q100 reliability and simpler implementation in cost-sensitive Tier 2 modules.

FAQ
What is the minimum input voltage required for TPS62260TDRVRQ1 to regulate a 1.8 V output at 600 mA?
The minimum input voltage depends on load current, output tolerance, and MOSFET on-resistance. For TPS62260TDRVRQ1 delivering 1.8 V at 600 mA, VINmin ≈ 1.8 V + 0.6 A × (0.48 Ω + 0.11 Ω) = 2.154 V. This enables operation down to near-end-of-discharge for single-cell Li-ion batteries, extending usable runtime in portable automotive accessories.
Does TPS62260TDRVRQ1 support forced PWM mode, and how is it enabled?
Yes, TPS62260TDRVRQ1 supports forced PWM mode. To enable it, tie the MODE pin to VIN (not just logic high)-this overrides automatic PFM/PWM transition and locks the device into fixed 2.25 MHz operation regardless of load current, reducing output voltage ripple for noise-sensitive analog circuits like ADC references or RF synthesizers.
How does the voltage positioning feature in TPS62260TDRVRQ1 improve load transient performance?
TPS62260TDRVRQ1's voltage positioning raises the regulated output by +1% during light loads in Power Save Mode. When a sudden load step occurs (e.g., 10 mA → 500 mA), this pre-biased headroom absorbs initial droop-reducing worst-case undershoot by up to 18 mV compared to standard regulation, which improves stability for processors and memory interfaces.
What is the thermal resistance (RθJA) of the TPS62260TDRVRQ1 in its 2×2 mm SON package?
The TPS62260TDRVRQ1 in the DRV (2 mm × 2 mm SON) package has a junction-to-ambient thermal resistance (RθJA) of 76°C/W under standard JEDEC 2S2P test conditions. With proper PCB copper pour under the exposed thermal pad, actual board-level RθJA can reach ≤45°C/W-enabling full 600 mA output at +85°C ambient without derating.
Can TPS62260TDRVRQ1 be used with ceramic output capacitors, and what value is recommended?
Yes, TPS62260TDRVRQ1 is fully compatible with ceramic output capacitors. The datasheet specifies 10 μF (0603 case, X5R/X7R dielectric) as the standard value for optimal stability and transient response. Using ≥10 μF ensures phase margin >45° across temperature and load, while lower values may cause ringing or instability during large load steps.
