Product details
Overview
TPS62260DRVR from Texas Instruments is a synchronous step-down DC/DC converter optimized for battery-powered portable electronics. It delivers up to 600 mA output current from 2 V–6 V input, operates at 2.25 MHz fixed switching frequency, supports power save mode (PFM) at light loads with 15-μA quiescent current, and features adjustable output voltage (0.6 V to VIN) via external feedback divider - used in mobile phone core logic rails.
For engineers reviewing the TPS62260DRVR datasheet, TPS62260DRVR pinout, TPS62260DRVR application, or TPS62260DRVR equivalent, key selection criteria include its 2.25-MHz PWM/PFM dual-mode operation, 6-pin WSON package footprint, MODE pin-controlled noise-performance trade-off, and 100% duty cycle capability for Li-ion battery end-of-discharge support.
Technical Context
The TPS62260DRVR implements voltage-mode control with input voltage feed-forward for fast line/load regulation and stable operation with small ceramic capacitors. Its internal 0.6-V reference enables precise output setting, while dynamic voltage positioning (+1% in PFM mode) reduces load-step undershoot/overshoot.
It integrates high-side (480 mΩ max RDS(on)) and low-side (380 mΩ max RDS(on)) MOSFETs, features undervoltage lockout (1.85 V falling threshold), thermal shutdown (140°C), and soft-start (250 μs ramp-up). The MODE pin selects between automatic PFM/PWM transition or forced PWM - critical for EMI-sensitive subsystems.
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), two/three-cell alkaline, and 3.3/5-V rails without external regulators. |
| Output Current | Up to 600 mA - sufficient for DSP cores, application processors, and RF transceivers in handheld devices. |
| Switching Frequency | 2.25 MHz (fixed) - enables use of compact 2.2-μH inductors and 10-μF ceramic output capacitors for <1-mm solution height. |
| Quiescent Current | 15 μA in PFM mode - extends battery life during standby/sleep states in always-on subsystems. |
| Feedback Reference | 0.6 V ±1.5% - allows accurate programmable output from 0.6 V to VIN using standard resistor dividers. |
| Shutdown Current | <1 μA - minimizes leakage when system is powered off, preserving battery charge over long idle periods. |
| Thermal Shutdown | 140°C with 20°C hysteresis - protects against sustained overload or poor PCB thermal design without latch-off. |
Pinout & Package
TPS62260DRVR uses a 6-pin 2 mm × 2 mm × 0.8 mm WSON package with exposed thermal pad (DRV designation). Pin 6 is GND-connected power pad for enhanced thermal performance and EMI reduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Power input supply | Accepts 2–6 V; requires local 4.7-μF ceramic decoupling to suppress high-frequency ripple and ensure stability. |
| GND | Ground reference | Signal and power return; must be connected to thermal pad (Pin 6) for optimal thermal dissipation and noise immunity. |
| EN | Enable control input | Active-high logic; pulling low disables regulator and reduces current draw to <1 μA - used for power sequencing. |
| SW | Switch node | Connects to inductor; carries high di/dt switching current - requires short, low-inductance routing to minimize EMI. |
| FB | Feedback input | Senses output voltage via external resistor divider; sensitive to noise - route away from SW and inductor. |
| MODE | Operation mode select | Pull high for forced PWM (low-noise, lower light-load efficiency); pull low for auto PFM/PWM (high efficiency, +1% voltage positioning). |
Key Features
| Feature | Design Value |
|---|---|
| Dynamic Voltage Positioning | Maintains output 1% above nominal in PFM mode to absorb sudden load steps without undershoot - critical for processor core rails. |
| 100% Duty Cycle Operation | Enables regulation down to VIN ≈ VOUT + IOUT×(RDS(on)+RL) - maximizes usable battery voltage range in Li-ion systems. |
| Integrated Power MOSFETs | High-side (480 mΩ max) and low-side (380 mΩ max) switches eliminate external FETs and gate drivers - reduces BOM count and layout area. |
| Fast Soft-Start | Ramps output from 5% to 95% of target in 250 μs - limits inrush current and prevents input rail collapse on weak sources like batteries. |
| Undervoltage Lockout | Disables output below 1.85 V (falling) - prevents brownout operation and excessive battery discharge in portable equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62261DDCR | Fixed 1.8-V output; no MODE pin; SOT-5 package (2.9 mm × 1.6 mm) | Eliminates external feedback resistors but lacks output adjustability and PWM-forced mode | Select when board space permits larger SOT-5 and fixed 1.8-V rail simplifies design |
| TPS62740DSSR | Lower IQ (360 nA), 200-mA output, 2-MHz switching, WSON-8 package | Optimized for coin-cell and energy-harvesting systems - not suitable for >300-mA loads | Choose only for ultra-low-power, sub-200-mA applications where nanoscale IQ outweighs current capability |
Compared with TPS62260DRVR, TPS62261DDCR trades flexibility (adjustable output, MODE control) for simplicity and cost in fixed-rail designs, while TPS62740DSSR targets radically different ultra-low-power niches - neither matches the 600-mA capability and dual-mode control of TPS62260DRVR in mid-power portable systems.

FAQ
What is the maximum output current capability of the TPS62260DRVR?
The TPS62260DRVR delivers up to 600 mA output current when VIN ≥ 2.5 V. At lower input voltages (2.3–2.5 V), maximum output drops to 300 mA; below 2.3 V, it is limited to 150 mA. This stepped current rating ensures safe operation across the full 2–6 V input range while maintaining thermal integrity in the 2-mm × 2-mm WSON package.
How does the MODE pin affect TPS62260DRVR operation?
The MODE pin on the TPS62260DRVR selects between two operating modes: pulled low (to GND) enables automatic PFM/PWM transition for highest light-load efficiency and dynamic voltage positioning; pulled high (to VIN) forces fixed-frequency PWM mode for predictable EMI and reduced output ripple - essential in noise-sensitive analog sections. Mode switching is allowed during operation.
Can the TPS62260DRVR support 100% duty cycle operation, and why does it matter?
Yes, the TPS62260DRVR enters 100% duty cycle mode as VIN approaches VOUT, maintaining regulation even when input falls to VOUT + IOUT×(RDS(on)+RL). This feature is critical in Li-ion-powered devices, allowing full utilization of the battery's 4.2 V → 2.7 V discharge curve - extending operational time by up to 15% compared to regulators lacking dropout optimization.
What is the feedback reference voltage of the TPS62260DRVR, and how is output voltage set?
The TPS62260DRVR uses an internal 0.6-V reference voltage (±1.5% tolerance in PWM mode) at the FB pin. Output voltage is set by an external resistor divider: VOUT = 0.6 V × (1 + R1/R2). Recommended R2 values are 180 kΩ or 360 kΩ to balance noise immunity and divider current; total resistance should not exceed ~1 MΩ.
Does the TPS62260DRVR require an external feed-forward capacitor, and what value is recommended?
Yes, the TPS62260DRVR requires an external feed-forward capacitor (C1) from FB to ground to optimize load transient response. The datasheet specifies 22 pF to 33 pF (COG/NPO ceramic); 22 pF is recommended for most designs. This capacitor improves phase margin and reduces output voltage deviation during rapid load steps - especially critical for processor core supplies.
