Product details
Overview
TPS62260QDRVRQ1 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 2 V–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 media players and low-power DSP supplies.
For engineers reviewing the TPS62260QDRVRQ1 datasheet, TPS62260QDRVRQ1 pinout, TPS62260QDRVRQ1 application, or TPS62260QDRVRQ1 equivalent, key selection criteria include its AEC-Q100 qualification, 15 μA quiescent current in PFM mode, 2×2 mm SON-6 package, 100% duty cycle capability for low-dropout operation, and MODE pin-controlled PWM/PSM transition behavior.
Technical Context
The TPS62260QDRVRQ1 uses voltage-mode control with input voltage feed-forward for fast line/load regulation and enables small ceramic capacitor usage. Its dual-mode operation-fixed-frequency PWM at moderate-to-heavy loads and automatic PFM entry at light loads-maintains high efficiency across the full 0.01–600 mA load range.
Dynamic voltage positioning raises the regulated output by +1% in Power Save Mode to reduce transient undershoot/overshoot during load steps. The MODE pin directly selects between forced PWM (MODE = VIN) and auto-transitioning PFM/PWM (MODE = GND), with no external components required for mode switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2 V to 6 V - supports single Li-ion cells (including extended-range 4.2 V), two/three alkaline cells, and 3.3 V/5 V rails. |
| Max Output Current | 600 mA - sustained at VIN ≥ 2.5 V; reduced to 300 mA at 2.3–2.5 V and 150 mA at 2–2.3 V for safe operation. |
| Switching Frequency | 2.25 MHz (±12.5%) - enables compact 2.2 μH inductors and 0603-size capacitors; allows <1-mm solution height. |
| Quiescent Current | 15 μA (typ) in PFM mode - minimizes battery drain during standby in always-on portable systems. |
| Output Voltage Accuracy | ±1.5% in PWM mode - ensures stable core supply for DSPs and microcontrollers without external trimming. |
| Shutdown Current | <1 μA - meets automotive low-power requirements during vehicle sleep modes. |
| Thermal Shutdown | 140°C with 20°C hysteresis - protects against sustained overload or poor PCB thermal design. |
Pinout & Package
TPS62260QDRVRQ1 is housed in a thermally enhanced 2×2×0.8 mm SON-6 package with exposed thermal pad (DRV variant). Pin 1 is SW (switch node), Pin 2 is MODE (mode select), Pin 3 is FB (feedback), Pin 4 is EN (enable), Pin 5 is VIN (input power), Pin 6 is GND (power ground).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW | Switch Node | Connects internal high-side/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 noise-sensitive analog sections. |
| FB | Feedback Input | Accepts resistor divider for adjustable output; fixed-output variants internally connect divider-this part is adjustable, so FB must be externally configured. |
| EN | Enable Input | Active-high logic; used for power sequencing and system-level shutdown; must be terminated to avoid floating state. |
| VIN | Power Input | Supplies internal circuitry and high-side switch; requires local 4.7 μF ceramic decoupling close to pin. |
| GND | Power Ground | Common return path for input/output currents; must be connected to exposed thermal pad for thermal performance and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive Qualification | AEC-Q100 Grade 2 (–40°C to +105°C ambient) - validated for infotainment, ADAS camera modules, and body electronics. |
| Voltage Positioning | +1% output offset in PFM mode - reduces dynamic voltage deviation during 10–100 mA load transients without adding external compensation. |
| 100% Duty Cycle Operation | Enables dropout as low as IO × (RDS(on)HS + DCRinductor) - extends usable battery life down to ~2.0 V for 1.8 V outputs. |
| Soft Start | 250 μs VOUT ramp time (5%→95%) - limits inrush current into downstream capacitance and prevents brownout of shared rails. |
| Low-Ripple PFM Mode | Single-threshold PFM comparator with time-controlled pulses - achieves <15 mVpp ripple at 10 mA with 2.2 μH/10 μF output filter. |

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 pinout, package, and electrical specs except FB pin is internally connected. | Eliminates external resistor divider; suited for systems where 1.8 V is standard and no adjustment needed. | Select when output voltage is fixed and board space for feedback resistors is constrained. |
| TPS62826QDMQRQ1 | Higher 1.2 A output, 4 MHz switching, lower IQ (1.5 μA), same 2×2 mm QFN but 8-pin; requires different layout and external compensation. | Supports higher-current SoCs and tighter EMI filtering; not drop-in due to pin count and control loop differences. | Choose for next-gen designs needing >600 mA or ultra-low IQ; requires redesign of feedback and compensation network. |
Compared with TPS62261TDRVRQ1, TPS62260QDRVRQ1 offers design flexibility through adjustable output but adds two resistors; versus TPS62826QDMQRQ1, it trades peak current and IQ for proven AEC-Q100 compatibility and simpler implementation in cost-sensitive automotive modules.

FAQ
What is the maximum output current capability of the TPS62260QDRVRQ1 under typical conditions?
The TPS62260QDRVRQ1 delivers up to 600 mA continuous output current when input voltage is ≥2.5 V. At lower inputs (2.3–2.5 V), max output drops to 300 mA; below 2.3 V, it is limited to 150 mA to maintain regulation and thermal safety. These values are specified in the Electrical Characteristics table and verified across temperature.
How does the MODE pin affect the operation of the TPS62260QDRVRQ1?
The MODE pin on the TPS62260QDRVRQ1 selects between two operating modes: pulling MODE to GND enables automatic Power Save Mode (PFM at light loads, PWM at heavy loads), while pulling MODE to VIN forces fixed-frequency PWM operation regardless of load. This direct hardware control allows real-time noise-performance trade-offs without firmware intervention.
Is the TPS62260QDRVRQ1 pin-compatible with other devices in the TPS6226x-Q1 family?
Yes, all TPS6226x-Q1 variants-including TPS62260QDRVRQ1, TPS62261TDRVRQ1, TPS62262TDRVRQ1, and TPS62263TDRVRQ1-share identical 2×2 mm SON-6 package and pinout. Only the FB connection differs: TPS62260QDRVRQ1 requires external resistors for adjustment, while fixed-output versions internally terminate FB.
What thermal considerations apply to the TPS62260QDRVRQ1 in automotive applications?
The TPS62260QDRVRQ1 features thermal shutdown at 140°C with 20°C hysteresis and is rated for operation up to +105°C ambient. Its DRV package includes an exposed thermal pad that must be soldered to a PCB copper pour for effective heat dissipation-TI recommends ≥120 mm² of 2-oz copper connected via ≥4 thermal vias to inner ground planes.
Can the TPS62260QDRVRQ1 support 100% duty cycle operation, and what is its practical benefit?
Yes, the TPS62260QDRVRQ1 enters 100% duty cycle mode when VIN approaches VOUT, maintaining regulation down to VIN ≈ VOUT + IO × (RDS(on)HS + DCRinductor). This extends usable battery life in Li-ion systems by enabling full discharge from 4.2 V down to ~2.0 V for a 1.8 V output, maximizing energy extraction.
