Product details
Overview
TPS62273DRVR 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 with input voltage range 2 V to 6 V, selectable fixed output voltages of 2.5 V (VSEL = 0) or 3.3 V (VSEL = 1), and operates in PWM/Power Save Mode for high efficiency across load range. It powers low-power processor cores in smartphones and navigation systems.
For engineers reviewing the TPS62273DRVR datasheet, TPS62273DRVR pinout, TPS62273DRVR application, or TPS62273DRVR equivalent, this page provides verified technical context, confirmed pin functions, real-world application roles, and validated alternative options - all derived from TI's official SLVS799C datasheet and product folder.
Technical Context
The TPS62273DRVR uses voltage-mode control with input voltage feed-forward for fast line/load regulation and supports automatic transition between fixed-frequency 2.25 MHz PWM mode and PFM Power Save Mode at light loads. Its internal high-precision feedback divider eliminates external resistor networks for output voltage setting.
It features 100% duty-cycle operation for lowest dropout, undervoltage lockout (1.85 V falling threshold), thermal shutdown (140 °C), and integrated short-circuit protection via forward current limit (0.56–0.84 A). The VSEL pin enables dynamic voltage scaling between two factory-programmed outputs without external components.
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 | 2.5 V (VSEL = 0) or 3.3 V (VSEL = 1) - factory-trimmed, no external resistors required; enables dynamic core voltage scaling. |
| Max Output Current | 400 mA - sustained delivery under PWM mode; limited by internal MOSFET RDS(on) and thermal design. |
| Switching Frequency | 2.25 MHz (typ.) - enables use of small 2.2 µH inductor and 10 µF ceramic capacitors for compact <21.5 mm² solution. |
| 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; supports system-level power gating. |
| Package | 2 mm × 2 mm × 0.8 mm SON-6 with PowerPad - thermally enhanced for high-current density in thin-profile portable designs. |
Pinout & Package
The TPS62273DRVR is housed in a 2 mm × 2 mm, 6-pin SON package (DRV designation) with exposed thermal pad (PowerPad™) on underside for enhanced heat dissipation. Pin numbering follows top-view layout with pin 1 at SW terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - SW | Switch node | Connects to inductor; carries high-frequency pulsed current; requires tight layout to minimize EMI and switching losses. |
| 2 - VSEL | Voltage select input | Digital control pin: logic high selects 3.3 V output, logic low selects 2.5 V; enables real-time core voltage adjustment. |
| 3 - FB | Feedback input | Internally connected to precision voltage divider; must be tied directly to output capacitor for fixed-VOUT operation. |
| 4 - EN | Enable input | Active-high logic control: drives high to enable regulator, low to enter <1 µA shutdown state; supports power sequencing. |
| 5 - VIN | Input power supply | Accepts 2–6 V; requires local 4.7 µF ceramic decoupling close to pin to suppress high-frequency ripple. |
| 6 - GND | Ground reference | Power and signal ground; must be connected to thermal pad for optimal thermal performance and noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Pin-selectable dual-output voltage | 2.5 V / 3.3 V selection via single VSEL logic level - eliminates external resistor network and saves PCB area. |
| Automatic PWM-to-PFM transition | Seamless mode switch at light load - maintains >85% efficiency down to 10 µA output current without manual control. |
| Voltage positioning in PFM mode | ±1% output voltage tolerance maintained during PFM pulses - minimizes ripple without requiring larger output caps. |
| 100% duty-cycle low-dropout operation | Supports VIN as low as VOUT + IOUT×(RDS(on)+RL) - extends usable battery life by extracting energy down to ~2.1 V. |
| Integrated thermal shutdown | 140 °C trip with 20 °C hysteresis - protects device during overload or poor heatsinking; auto-recovery on cooldown. |
Applications
| Smartphone Application Processor Core Supply | Portable Navigation System RF/BB Power Rail |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62260DRVR | Same 2×2 SON package, 2.25 MHz, but fixed 1.2 V output; lacks VSEL pin and PFM voltage positioning. | Suitable only for static 1.2 V core rails; cannot support dynamic voltage scaling or 2.5/3.3 V outputs. | Select only if fixed 1.2 V is required and VSEL functionality is unnecessary. |
| TPS62740DRYR | Lower IQ (360 nA shutdown, 360 nA PFM), 300 mA max, 2.25 MHz, but supports 1.8–3.3 V adjustable output via external resistors. | Requires external feedback resistors; larger solution size; optimized for ultra-low-power IoT sensors, not high-current apps. | Prefer for battery-life-critical wearables; avoid when >300 mA or VSEL-driven dynamic scaling is needed. |
Compared with TPS62273DRVR, TPS62260DRVR offers identical form factor and frequency but sacrifices programmability and output flexibility, while TPS62740DRYR trades current capability and pin simplicity for extreme ultra-low-power operation - making TPS62273DRVR the optimal choice for space-constrained, dynamically scaled 2.5/3.3 V portable power rails.

FAQ
What output voltages does the TPS62273DRVR support?
The TPS62273DRVR supports two factory-programmed fixed output voltages: 2.5 V when VSEL is pulled low (GND), and 3.3 V when VSEL is pulled high (VIN). These values are trimmed internally - no external resistors are required. The TPS62273DRVR datasheet specifies ±3% tolerance over temperature and load, with voltage positioning in PFM mode maintaining ±1% regulation.
Does the TPS62273DRVR require external compensation components?
No, the TPS62273DRVR does not require external compensation components. Its internal voltage-mode control loop with feed-forward is fully compensated for standard 2.2 µH inductors and 10 µF ceramic output capacitors. The FB pin connects directly to the output capacitor in fixed-VOUT mode, eliminating need for external resistor dividers or compensation networks - a key enabler of its <21.5 mm² solution size.
How does the TPS62273DRVR handle low-input-voltage conditions near battery depletion?
The TPS62273DRVR enters 100% duty-cycle mode when VIN approaches VOUT, sustaining regulation down to ~2.1 V input at 2.5 V output (depending on load and inductor DCR). This extends usable battery capacity beyond conventional buck converters. Its undervoltage lockout (UVLO) disables operation below 1.85 V (falling), preventing erratic behavior and excessive battery discharge.
Can the TPS62273DRVR be used in place of the TPS62272DRVR?
The TPS62273DRVR and TPS62272DRVR share identical pinout, package, and electrical architecture but differ in output voltage mapping: TPS62272DRVR offers 2.1 V / 3.3 V, while TPS62273DRVR offers 2.5 V / 3.3 V. They are not drop-in replacements - substituting one for the other requires verifying system-level voltage margin, especially for 2.1 V vs. 2.5 V logic interfaces and core supply requirements.
What is the thermal performance of the TPS62273DRVR in its 2×2 SON package?
The TPS62273DRVR in DRV package has RθJA = 76 °C/W and maximum power dissipation of 1300 mW at TA ≤ 25 °C. With proper PCB copper pour under the PowerPad™ and 2 oz. internal ground plane, it sustains 400 mA continuous output at ambient ≤ 60 °C. Thermal shutdown activates at 140 °C junction temperature with 20 °C hysteresis, ensuring robust operation under transient overload.
