Product details
Overview
TPS62260DRVTG4 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 a 2 V–6 V input, operates at 2.25 MHz fixed switching frequency, supports power save mode (PFM) at light loads, and features adjustable output voltage via external feedback resistors with ±1.5% PWM-mode accuracy. It is used in mobile phone core logic rails requiring compact, high-efficiency regulation.
For engineers reviewing the TPS62260DRVTG4 datasheet, TPS62260DRVTG4 pinout, TPS62260DRVTG4 application, or TPS62260DRVTG4 equivalent, key selection criteria include its 2.25-MHz operation enabling small passive components, 15-μA quiescent current in PFM mode, 100% duty cycle low-dropout capability, MODE pin-controlled PWM/PFM transition, and WSON-6 package suitability for space-constrained PCB layouts.
Technical Context
The TPS62260DRVTG4 employs voltage-mode control with input voltage feed-forward for fast line/load regulation and stable operation with ceramic capacitors. Its dual-mode architecture automatically transitions between fixed-frequency PWM (for noise-sensitive applications when MODE = VIN) and pulse-frequency modulation PFM (when MODE = GND), maintaining >80% efficiency from 1 mA to 600 mA load.
It integrates high-side (240–480 mΩ) and low-side (185–380 mΩ) MOSFETs, features dynamic voltage positioning (+1% nominal output in PFM), undervoltage lockout (1.85 V falling threshold), thermal shutdown (140°C), and soft-start (250 μs ramp-up). The 6-pin WSON package includes an exposed thermal pad for enhanced power dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2 V to 6 V - supports single-cell Li-ion, two/three-cell alkaline, and 3.3 V/5 V rails without external regulators. |
| Output Current | Up to 600 mA - sufficient for DSP cores, RF transceivers, and application processors in handheld devices. |
| Switching Frequency | 2.25 MHz (±12.5%) - enables use of 2.2 μH inductors and 10 μF ceramic capacitors for <1-mm solution height. |
| Quiescent Current | 15 μA (PFM, no switching) - extends battery life in standby/sleep modes of portable equipment. |
| Feedback Reference | 600 mV - sets adjustable output range from 0.6 V to VIN; allows precise core voltage tuning via resistor divider. |
| Shutdown Current | 0.1–1 μA - minimizes battery drain during system off-state; EN pin controls full rail disable. |

| Thermal Resistance | RθJA = 67.8°C/W (WSON-6) - supports continuous 600 mA operation at +85°C ambient with minimal heatsinking. |
Pinout & Package
The TPS62260DRVTG4 is housed in a 2.0 mm × 2.0 mm × 0.8 mm WSON-6 package with exposed thermal pad (Pin 6 = GND). This RoHS-compliant, moisture-sensitive level-2 package enables high-density layout and efficient thermal transfer to PCB copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 5) | Power input | Accepts 2–6 V; requires local 4.7 μF ceramic decoupling; connects to input capacitor and inductor source. |
| GND (Pin 6) | Ground reference | Primary return path for power and control circuits; must be connected to large PCB ground plane and thermal pad. |
| EN (Pin 4) | Enable control | Active-high logic input; pulling low disables regulator and reduces current draw to <1 μA; supports power sequencing. |
| SW (Pin 1) | Switch node | Connects internal high/low-side MOSFETs to external inductor; carries high di/dt; requires short, low-inductance routing. |
| FB (Pin 3) | Feedback input | Senses output voltage via external resistor divider; high-impedance input (1 μA bias); routed away from SW/inductor. |
| MODE (Pin 2) | Operation mode select | Pull to GND for automatic PFM/PWM transition; pull to VIN for forced fixed-frequency PWM; enables noise-sensitive design. |
Key Features
| Feature | Design Value |
|---|---|
| Dynamic Voltage Positioning | Maintains +1% output offset in PFM mode to reduce load-step undershoot/overshoot and improve transient response. |
| 100% Duty Cycle Operation | Enables dropout as low as IOUT × (RDS(on) + DCRL) - maximizes usable battery voltage range in Li-ion systems. |
| Integrated Power MOSFETs | High-side RDS(on) = 240–480 mΩ, low-side RDS(on) = 185–380 mΩ - eliminates external switches and simplifies BOM. |
| Soft-Start Ramp | 250 μs (5% → 95% VOUT) - limits inrush current and prevents input rail collapse during power-up. |
| Undervoltage Lockout | 1.85 V (falling), 1.95 V (rising) - protects battery from deep discharge and ensures clean startup above safe threshold. |
| Thermal Shutdown | 140°C activation with 20°C hysteresis - prevents permanent damage during overload or poor thermal design. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62261DRVR | Fixed 1.8 V output; no MODE pin; auto PFM/PWM transition only. | Eliminates FB resistor network but lacks output adjustability and forced-PWM capability. | Select when fixed 1.8 V is acceptable and board space savings from omitted resistors outweigh flexibility loss. |
| TPS62067QDSGRQ1 | AEC-Q100 qualified; 600 mA; 2.5 V–6 V input; 3% output accuracy; no MODE pin. | Designed for automotive infotainment and ADAS; higher temp range (–40°C to +125°C); no PFM voltage positioning. | Choose for automotive-grade reliability where extended junction temperature and qualification supersede PFM optimization. |
Compared with TPS62260DRVTG4, TPS62261DRVR trades programmability and noise control for simplicity and cost, while TPS62067QDSGRQ1 sacrifices PFM precision and MODE flexibility to meet automotive safety and thermal requirements - making TPS62260DRVTG4 optimal for consumer portable designs demanding both efficiency and design adaptability.

FAQ
What is the maximum output current capability of the TPS62260DRVTG4 under typical conditions?
The TPS62260DRVTG4 delivers up to 600 mA output current when input voltage is 2.5 V–6 V. At lower inputs (2.0 V–2.3 V), maximum output current is reduced to 150 mA due to internal current limit and MOSFET RDS(on) constraints. This derating ensures stable operation across the full 2 V–6 V input range specified in the SLVS763E datasheet.
How does the MODE pin affect the operation of the TPS62260DRVTG4?
The MODE pin on the TPS62260DRVTG4 selects between two operating modes: when pulled to GND, it enables automatic PFM/PWM transition for highest light-load efficiency; when pulled to VIN, it forces fixed-frequency PWM operation regardless of load, reducing output voltage ripple and shifting noise to a predictable 2.25 MHz frequency - critical for noise-sensitive analog circuits.
Can the TPS62260DRVTG4 regulate output voltage when input voltage drops close to the output setting?
Yes, the TPS62260DRVTG4 supports 100% duty cycle operation, allowing it to maintain regulation even when VIN approaches VOUT. For example, with a 1.2 V output and 600 mA load, it can sustain regulation down to ~1.35 V input (accounting for RDS(on) and inductor DCR), extending usable battery life in single-cell Li-ion applications beyond competing buck converters.
What is the recommended output capacitor value and type for stable operation of the TPS62260DRVTG4?
Texas Instruments specifies a 10 μF X5R or X7R ceramic capacitor (e.g., Murata GRM188R60J106M) as the standard output capacitor for the TPS62260DRVTG4. Values between 4.7 μF and 22 μF are supported; smaller values increase ripple and reduce stability margin, while larger values lower ripple but may impact transient response. Y5V/Z5U dielectrics are not recommended due to capacitance drift.
Does the TPS62260DRVTG4 include built-in protection features?
Yes, the TPS62260DRVTG4 integrates multiple protection functions: undervoltage lockout (1.85 V falling threshold), thermal shutdown (140°C activation with 20°C hysteresis), overcurrent limiting on both high-side and low-side MOSFETs (typ. 1.0 A), and short-circuit protection. These features operate autonomously without external components, ensuring robustness in portable and battery-operated systems.
