Product details
Overview
TPS62260DDCRG4 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, and features adjustable output voltage (0.6 V to VIN) with ±1.5% PWM-mode accuracy. It is used in mobile phones and low-power DSP supplies where compact size and high efficiency across load range are critical.
For engineers reviewing the TPS62260DDCRG4 datasheet, TPS62260DDCRG4 pinout, TPS62260DDCRG4 application, or TPS62260DDCRG4 equivalent, key selection considerations include its SOT-5 package footprint, MODE pin-controlled PFM/PWM transition, 15-μA quiescent current in PFM mode, 100% duty cycle dropout operation, and compatibility with 2.2-μH inductors and 10-μF ceramic output capacitors.
Technical Context
The TPS62260DDCRG4 implements voltage-mode control with input voltage feed-forward for fast line/load regulation. Its internal architecture includes dual MOSFET switches (240 mΩ high-side, 185 mΩ low-side), a 2.25-MHz oscillator, and a dedicated PFM comparator enabling dynamic voltage positioning (+1% nominal output in light-load mode).
It integrates undervoltage lockout (1.85 V falling threshold), thermal shutdown (140°C), soft-start (250 μs ramp-up), and short-circuit protection via current-limit comparators on both FETs. The MODE pin selects between automatic PFM/PWM transition (MODE = GND) or forced PWM (MODE = VIN), while EN enables/disables the device with <1 μA shutdown current.
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 core logic, RF transceivers, and low-power processors in portable devices. |
| Switching Frequency | 2.25 MHz (fixed) - enables use of small 2.2-μH inductors and 0603-size ceramic capacitors for <1-mm solution height. |
| Quiescent Current | 15 μA (PFM mode, no load) - extends battery life in standby/sleep states of handheld equipment. |
| Output Voltage Accuracy | ±1.5% in PWM mode - ensures stable core voltage for microcontrollers and memory interfaces under varying load/temperature. |
| Shutdown Current | 0.1 μA - minimizes battery drain during system off-state; meets stringent energy budget requirements. |
| Feedback Reference Voltage | 600 mV - sets adjustable output range from 0.6 V to VIN using external resistor divider; simplifies multi-rail designs. |
Pinout & Package
TPS62260DDCRG4 uses the SOT-5 (DDC) package: 2.90 mm × 1.60 mm, 5-pin surface-mount, lead-free, RoHS-compliant. Thermal pad not present; standard SOT-23 footprint with exposed pad omitted.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Power input | Accepts 2 V–6 V supply; connects to input capacitor (4.7 μF recommended); must be decoupled near package. |
| GND | Ground reference | Primary return path for power and feedback circuits; requires low-impedance PCB connection to minimize noise coupling. |
| EN | Enable control | Active-high digital input; pulling low disables converter and reduces current to <1 μA; supports power sequencing. |
| FB | Feedback sense | Connects to resistor divider from VOUT; internal 600-mV reference sets output voltage; routing away from SW avoids noise injection. |
| SW | Switch node | Drives external inductor; carries high di/dt; requires tight layout, minimal trace length, and ground plane clearance to reduce EMI. |
Key Features
| Feature | Design Value |
|---|---|
| Power Save Mode (PFM) | Automatically engages below ~100 mA load, reducing quiescent current to 15 μA while maintaining +1% voltage positioning for transient headroom. |
| 100% Duty Cycle Operation | Enables regulation down to VIN ≈ VOUT, maximizing usable battery voltage range-critical for extending runtime in Li-ion systems. |
| Dynamic Voltage Positioning | Raises regulated output by 1% in PFM mode to counteract load-step undershoot, improving stability without external compensation. |
| Fast Soft-Start | Ramps VOUT from 5% to 95% in 250 μs, limiting inrush current and preventing input rail collapse from weak sources like coin cells. |
| Integrated Protection | Includes thermal shutdown (140°C), undervoltage lockout (1.85 V), and cycle-by-cycle current limiting on both MOSFETs for robust field operation. |

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; auto PFM/PWM transition only; same SOT-5 package and 600 mA rating. | Eliminates external feedback resistors but lacks output adjustability; suited for single-rail systems with fixed voltage requirement. | Select when board space is constrained and 1.8 V is the sole required output; avoid if programmable VOUT or MODE control is needed. |
| TPS62231DRVR | 2.25 MHz, 300 mA, SOT-5, 2 V–6 V input; lower current rating; 17 μA quiescent current; no MODE pin. | Targeted at lower-power peripherals (e.g., sensors, interface ICs); insufficient for processor cores requiring >400 mA. | Choose for cost-sensitive, low-current applications where 300 mA suffices; verify thermal performance at max load before substitution. |
Compared with TPS62260DDCRG4, TPS62261DDCR trades adjustability for BOM simplification, while TPS62231DRVR reduces current capability and removes MODE control-both require revalidation of loop stability and transient response in existing layouts.

FAQ
What is the maximum output current capability of the TPS62260DDCRG4 under typical conditions?
The TPS62260DDCRG4 delivers up to 600 mA output current when VIN ≥ 2.5 V. At lower input voltages (2.3 V–2.5 V), the rated output drops to 300 mA, and at 2.0 V–2.3 V, it is limited to 150 mA due to internal current-limit thresholds and MOSFET RDS(on) constraints. These values are specified in the Electrical Characteristics table of the SLVS763E datasheet and verified across –40°C to 85°C ambient temperature.
Does the TPS62260DDCRG4 support adjustable output voltage, and how is it configured?
Yes, the TPS62260DDCRG4 supports fully adjustable output voltage from 0.6 V to VIN using an external resistor divider connected to the FB pin. The internal reference is 600 mV, so 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. This configuration is confirmed in Section 9.2.2.1 of the SLVS763E datasheet.
How does the MODE pin function on the TPS62260DDCRG4, and what happens when it is left unconnected?
The MODE pin on the TPS62260DDCRG4 selects between power save mode (MODE = GND) and forced PWM mode (MODE = VIN). When unconnected, the pin is internally pulled down via a weak current source, defaulting to power save mode with automatic PFM/PWM transition. This behavior is documented in the Pin Functions table (Section 6) and Feature Description (Section 8.3.3) of the SLVS763E datasheet.
What thermal performance can be expected from the TPS62260DDCRG4 in the SOT-5 package?
In the SOT-5 (DDC) package, the TPS62260DDCRG4 has a junction-to-ambient thermal resistance (RθJA) of 226.9°C/W. At 600 mA output with 3.6 V input and 1.2 V output, typical power dissipation is ~150 mW, resulting in ~34°C junction-to-ambient rise above ambient. Full derating is required above 65°C ambient per the Thermal Information table (Section 7.4) in SLVS763E.
Is the TPS62260DDCRG4 RoHS-compliant and lead-free?
Yes, the TPS62260DDCRG4 is RoHS-compliant and lead-free. Its package marking "DDCRG4" indicates TI's green packaging standard (G4 suffix), confirming compliance with JEDEC J-STD-020 moisture sensitivity level 1 and exemption from lead content restrictions per EU Directive 2011/65/EU. This is verified in TI's official Packaging Information document SPRP254.
