Product details
Overview
TPS62263DRVT from Texas Instruments is a 2.25-MHz synchronous step-down DC/DC converter delivering up to 600 mA output current from 2 V to 6 V input, with fixed 2.5 V output voltage, 15-μA quiescent current in power-save mode, and 2.25-MHz fixed-frequency PWM operation-designed for Li-ion battery-powered mobile phones and portable media players.
For engineers reviewing the TPS62263DRVT datasheet, TPS62263DRVT pinout, TPS62263DRVT application, or TPS62263DRVT equivalent, key selection criteria include its WSON-6 package footprint, MODE-pin controllable PFM/PWM transition, ±1.5% output voltage accuracy in PWM mode, 100% duty-cycle low-dropout capability, and thermal shutdown at 140°C.
Technical Context
The TPS62263DRVT employs voltage-mode control with input voltage feed-forward for fast line/load regulation and supports automatic PFM-to-PWM transition based on load current. Its integrated high-side (480 mΩ max) and low-side (380 mΩ max) MOSFETs enable synchronous rectification without external diodes.
Dynamic voltage positioning raises output by +1% in PFM mode to minimize transient undershoot; undervoltage lockout activates at 1.85 V (falling VIN); and soft-start limits inrush current with 250 μs ramp-up time from 5% to 95% of nominal VOUT.
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 |
| Output Voltage | Fixed 2.5 V - no external feedback resistors required; internal resistor divider configured |
| Max Output Current | 600 mA - sustained at VIN ≥ 2.5 V; derated to 300 mA at VIN = 2.3–2.5 V |
| Switching Frequency | 2.25 MHz (±12.5%) - enables use of small 2.2-μH inductors and 10-μF ceramic capacitors |
| Quiescent Current | 15 μA (PFM mode, no switching) - extends battery life in standby |
| Output Accuracy | ±1.5% in PWM mode - ensures stable core supply for DSPs and microcontrollers |
| Shutdown Current | 0.1–1 μA - minimizes battery drain when EN = GND |
| Thermal Shutdown | 140°C (typ), 20°C hysteresis - protects against sustained overload or poor PCB thermal design |
Pinout & Package
TPS62263DRVT is housed in a thermally enhanced 6-pin WSON package (2.0 mm × 2.0 mm × 0.8 mm), with exposed thermal pad (Pin 6) connected to GND for optimal heat dissipation. The package supports <1-mm solution height and is RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 5) | Power Input | Accepts 2–6 V input; requires 4.7-μF ceramic decoupling capacitor close to pin |
| GND (Pin 6) | Ground Reference | Primary power ground; thermal pad must be soldered to PCB GND plane for thermal performance |
| EN (Pin 4) | Enable Control | Active-high logic; pull low to enter shutdown (<1 μA IQ); supports power sequencing |
| SW (Pin 1) | Switch Node | Connects to inductor; high dv/dt node requiring short, low-inductance routing |
| FB (Pin 3) | Feedback Input | Internally tied to fixed 2.5 V divider; leave unconnected in fixed-output configuration |
| MODE (Pin 2) | Operation Mode Select | Pull to GND for auto PFM/PWM transition; pull to VIN for forced fixed-frequency PWM |
Key Features
| Feature | Design Value |
|---|---|
| Dynamic Voltage Positioning | Maintains +1% output offset in PFM mode to reduce load-step undershoot by >30 mV in typical 100-mA → 500-mA transients |
| 100% Duty-Cycle Operation | Enables dropout as low as VOUT + IOUT × (RDS(on)_HS + DCR_L); extends usable battery range down to ~2.7 V for 2.5 V output |
| Integrated Power MOSFETs | Eliminates need for external high-side/low-side switches; reduces BOM count and layout complexity |
| Fast Soft-Start | Ramps output from 5% to 95% of 2.5 V in 250 μs - prevents input rail collapse during cold start from weak sources |
| Short-Circuit Protection | Current-limit comparators on both MOSFETs limit peak switch current to 0.8–1.2 A, preventing latch-up under output fault |
Applications
| Mobile Phone Power Rail | Low-Power DSP Core Supply |
|---|---|
Use Scenario: Powers application processor I/O or modem subsystem in compact smartphones operating from single Li-ion cell (2.8–4.2 V).

Use Value: 15-μA IQ in PFM mode extends alkaline battery life by >2× versus comparable 500-μA buck converters at light loads. |
| Portable Media Player Audio Codec | Wearable Sensor Hub Supply |
Use Scenario: Provides low-noise 2.5 V bias to stereo audio DAC/ADC in MP3 players with mechanical buttons and OLED display. IC Role / Device Role / Timing Role: Fixed-output buck regulator with MODE-pin controllable PWM mode to suppress switching noise near sensitive analog circuitry.

IC Role / Device Role / Timing Role: High-efficiency step-down converter supporting wide input (2.0–3.6 V) and deep discharge tolerance. Use Value: 100% duty-cycle operation sustains 2.5 V output down to VIN = 2.7 V - extracting ~8% more energy from depleted battery vs non-100% ICs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62262DRVT | Fixed 1.2 V output; identical package, pinout, and electrical specs except VOUT | Requires redesign of downstream logic voltage levels; not suitable for 2.5 V I/O rails | Select only if system architecture mandates 1.2 V core supply and board layout permits no changes |
| TPS62231DRYT | Same 2.5 V output, but 3-MHz switching, 400-mA rating, and SOT-23-6 package (2.9 × 1.6 mm) | Larger footprint; lower max current; higher fSW demands tighter layout for EMI control | Choose when space allows larger package and 400 mA suffices; avoid if 600 mA peak load or minimal height (<1 mm) is required |
Compared with TPS62263DRVT, TPS62262DRVT offers identical performance at 1.2 V but cannot replace it without level-shifting; TPS62231DRYT provides same VOUT in a different package with reduced current capability and higher frequency-making TPS62263DRVT the optimal choice for space-constrained 600-mA 2.5 V applications.

FAQ
What is the output voltage of the TPS62263DRVT and is it adjustable?
The TPS62263DRVT has a factory-configured fixed output voltage of 2.5 V. It uses an internal resistor divider network, so the FB pin is not externally configurable. Unlike the adjustable TPS62260DRV, the TPS62263DRVT does not support output voltage changes via external resistors - its 2.5 V output is optimized for I/O rail and analog subsystem supply in portable devices.
Does the TPS62263DRVT require an external feedback resistor network?
No, the TPS62263DRVT does not require external feedback resistors. Its fixed 2.5 V output is set internally; the FB pin is pre-connected to the internal voltage divider and must be left unconnected in standard operation. Adding external components to FB may disrupt regulation or cause instability - the TPS62263DRVT is designed for plug-and-play integration with only VIN, SW, GND, EN, MODE, and output capacitors needed.
What package type and dimensions does the TPS62263DRVT use?
The TPS62263DRVT uses a 6-pin WSON package (designation DRV) measuring 2.0 mm × 2.0 mm × 0.8 mm with an exposed thermal pad. This thermally enhanced, leadless package supports <1-mm solution height and requires PCB land pattern per TI's SLVS763E datasheet - including solder paste stencil design for the thermal pad to ensure reliable thermal transfer and mechanical attachment.
How does the MODE pin affect operation of the TPS62263DRVT?
The MODE pin on the TPS62263DRVT selects between two operating modes: pulling MODE to GND enables automatic PFM/PWM transition for highest light-load efficiency, while pulling MODE to VIN forces continuous 2.25-MHz PWM operation - reducing output voltage ripple and simplifying EMI filtering. Both configurations are valid during active operation, allowing dynamic mode switching for adaptive power management in the TPS62263DRVT.
What is the maximum output current capability of the TPS62263DRVT across its input voltage range?
The TPS62263DRVT delivers up to 600 mA when VIN is 2.5 V or higher. At VIN = 2.3–2.5 V, maximum output current is derated to 300 mA; below 2.3 V, it supports only 150 mA. These limits reflect internal MOSFET RDS(on) and thermal constraints - actual achievable current also depends on PCB copper area, ambient temperature, and inductor DCR. Full 600-mA capability is guaranteed under recommended conditions in the TPS62263DRVT datasheet.
