Product details
Overview
TPS62272DRVT from Texas Instruments is a 2.25 MHz synchronous step-down DC-DC converter optimized for Li-ion battery-powered portable applications. It delivers up to 400 mA output current from 2 V to 6 V input, provides pin-selectable fixed outputs of 2.1 V (VSEL = 0) or 3.3 V (VSEL = 1), and operates in Power Save Mode at light loads to maintain high efficiency. It powers low-power processor cores in smartphones and navigation systems.
For engineers reviewing the TPS62272DRVT datasheet, TPS62272DRVT pinout, TPS62272DRVT application, or TPS62272DRVT equivalent, this page delivers verified technical context, confirmed pin functions, real-world application mappings, and validated alternative options - all grounded in TI's SLVS799C datasheet and official DRV package documentation.
Technical Context
The TPS62272DRVT uses voltage-mode control with input voltage feed-forward for fast line/load regulation and supports automatic transition between PWM (2.25 MHz fixed-frequency) and PFM modes. Its internal high-precision feedback divider eliminates external resistor networks for fixed-output variants.
It integrates high-side (240–480 mΩ) and low-side (180–380 mΩ) MOSFETs, features 100% duty-cycle operation for ultra-low dropout, and includes undervoltage lockout (1.85 V falling threshold), thermal shutdown (140 °C), and short-circuit protection via forward current limit (0.56–0.84 A).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2 V to 6 V - supports full Li-ion battery discharge curve (3.0–4.2 V nominal + extended range down to 2 V). |
| Output Voltage Options | 2.1 V (VSEL = GND) or 3.3 V (VSEL = VIN) - factory-trimmed, no external feedback resistors required. |
| Max Output Current | 400 mA - sustained delivery under PWM mode; limited by internal current sense and thermal design. |
| Switching Frequency | 2.25 MHz (typ.) - enables use of small 2.2 µH inductors and 10 µF ceramic capacitors for compact <22 mm² layout. |
| Quiescent Current | 15 µA (typ.) - achieved in Power Save Mode, critical for battery runtime in standby/sleep states. |
| Shutdown Current | 0.1–1 µA - ensures minimal battery drain when EN = GND in system-level power gating. |
| Package | DRV (SON-6, 2 mm × 2 mm × 0.8 mm) - thermally enhanced with exposed PowerPad for junction-to-board heat transfer. |
Pinout & Package
TPS62272DRVT is housed in a 6-pin SON (Small Outline No-lead) package, 2 mm × 2 mm × 0.8 mm, with an exposed PowerPad for thermal dissipation. The DRV package supports reflow soldering and achieves RθJA = 76 °C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 5) | Power Input | Primary DC input supply (2–6 V); requires local 4.7 µF ceramic decoupling close to pin. |
| GND (Pin 6) | Power Ground | Return path for input/output currents; must be connected to exposed PowerPad for thermal and electrical integrity. |
| EN (Pin 4) | Digital Enable | Active-high logic control; pulling low disables regulator and reduces IQ to sub-1 µA for system power sequencing. |
| SW (Pin 1) | Switch Node | Connection point for external inductor; carries high di/dt switching waveform - requires tight layout and ground plane clearance. |
| FB (Pin 3) | Feedback Input | Internally connected to precision voltage divider for fixed-output variants; left unconnected (not used) in TPS62272DRVT. |
| VSEL (Pin 2) | Voltage Select | Digital input selecting 2.1 V (low) or 3.3 V (high); compatible with standard CMOS logic levels across full VIN range. |
Key Features
| Feature | Design Value |
|---|---|
| Pin-selectable dual output | Eliminates external feedback network and saves PCB area - ideal for dynamic voltage scaling in low-power processors. |
| Power Save Mode with PFM | Maintains >85% efficiency at 10 µA load via automatic PWM-to-PFM transition and voltage positioning (±1% ripple control). |
| 100% duty-cycle operation | Extends usable battery life by regulating down to VIN – VOUT ≈ 200 mV (at 400 mA), leveraging full cell voltage range. |
| Integrated MOSFETs | Reduces BOM count and layout complexity - high-side RDS(on) ≤ 480 mΩ and low-side ≤ 380 mΩ at 3.6 V gate drive. |
| Thermal shutdown with hysteresis | Protects against sustained overload: shuts down at 140 °C, resumes at 120 °C (20 °C hysteresis) without latch-up. |
Applications
| Smartphone Application Processor Core | Portable Navigation System RF/BB Supply |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62262DRVR | Same 2×2 SON package, 2.25 MHz, but fixed 2.5 V output (no VSEL); 12 µA Q, 300 mA max IOUT. | Lacks dynamic voltage selection - suitable only for single-rail 2.5 V systems without scaling needs. | Select when board space and quiescent current are prioritized over dual-voltage flexibility. |
| TPS62740DSSR | Lower IQ (360 nA), 300 mA, 2.25 MHz, but 3.3 V fixed output only; requires external feedback for other voltages. | Optimized for ultra-low-power coin-cell applications - not rated for 400 mA or Li-ion input range. | Choose only for energy-harvesting or button-cell designs where sub-µA shutdown is mandatory. |
Compared with TPS62272DRVT, TPS62262DRVR trades VSEL flexibility for lower quiescent current and reduced output capability, while TPS62740DSSR sacrifices current capacity and input voltage range to achieve nanoamp-level shutdown - neither offers pin-compatible replacement nor identical dual-voltage functionality.

FAQ
What output voltages does the TPS62272DRVT support?
The TPS62272DRVT supports two factory-trimmed, pin-selectable output voltages: 2.1 V when VSEL is pulled low (GND), and 3.3 V when VSEL is pulled high (VIN). These values are specified in the Electrical Characteristics table (SLVS799C, p.3) with ±3% tolerance over temperature and line, and require no external feedback components.
Does the TPS62272DRVT require an external feedback resistor network?
No, the TPS62272DRVT does not require external feedback resistors. It uses an internal precision voltage divider optimized for its fixed 2.1 V / 3.3 V outputs. The FB pin is internally connected and must remain unconnected in standard operation - confirmed in the Terminal Functions section (SLVS799C, p.4) and Functional Block Diagram.
What is the maximum continuous output current of the TPS62272DRVT?
The TPS62272DRVT delivers up to 400 mA continuous output current under PWM operation with 2 V ≤ VIN ≤ 6 V and proper thermal management. At VIN < 2.5 V, the maximum drops to 150 mA due to internal current limiting - per the Electrical Characteristics table (SLVS799C, p.3).
How does the TPS62272DRVT manage efficiency at light loads?
The TPS62272DRVT automatically transitions from PWM to Power Save Mode (PFM) at light loads, reducing switching frequency and quiescent current to 15 µA typical. This maintains >85% efficiency down to 10 µA load, with voltage positioning limiting output ripple to ±1% - detailed in the Operation section (SLVS799C, p.12).
What package type and thermal characteristics does the TPS62272DRVT use?
The TPS62272DRVT uses the DRV package: a 2 mm × 2 mm, 6-pin SON with exposed PowerPad. Its thermal resistance is RθJA = 76 °C/W, supporting 1300 mW power dissipation at TA ≤ 25 °C, with derating of 13 mW/°C above that - per the Dissipation Ratings table (SLVS799C, p.2).
