Product details
Overview
TPS62293DRVR from Texas Instruments is a 1-A synchronous step-down DC/DC converter optimized for Li-ion battery-powered portable electronics. It delivers a fixed 1.8 V output from 2.3–6.0 V input, operates at 2.25 MHz fixed switching frequency, supports power save mode (PFM) at light loads with 15-μA quiescent current, and features dynamic voltage positioning for load transient response - used in mobile phone core logic rails.
For engineers reviewing the TPS62293DRVR datasheet, TPS62293DRVR pinout, TPS62293DRVR application, or TPS62293DRVR equivalent, key selection criteria include its 1.8 V fixed output, 2.25-MHz operation enabling compact 2.2-μH inductor use, WSON-6 (DRV) package thermal performance (RθJA = 67.8°C/W), and MODE pin-controlled PWM/PFM mode transition for noise-sensitive or efficiency-critical designs.
Technical Context
The TPS62293DRVR implements a fast-response voltage-mode control architecture with input voltage feed-forward, enabling stable regulation using small ceramic capacitors. Its dual-mode operation-forced PWM (MODE = high) for low-noise applications and automatic PFM (MODE = GND) for high light-load efficiency-is managed by an internal comparator monitoring output voltage deviation against a +1% positioned threshold.
Internally, it integrates high-side (240–480 mΩ) and low-side (185–380 mΩ) MOSFETs, a 0.6-V reference, undervoltage lockout (1.85 V fall), thermal shutdown (140°C), and 100% duty-cycle dropout capability. The FB pin is internally connected to a fixed resistor divider, eliminating external feedback components for the 1.8-V variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.8 V ±1.5% in PWM mode - eliminates need for external feedback resistors and simplifies BOM. |
| Input Voltage Range | 2.3 V to 6.0 V - supports full discharge curve of single-cell Li-ion (3.0–4.2 V) plus extended range for hybrid or boosted sources. |
| Max Output Current | 1000 mA at VIN ≥ 2.7 V - sufficient for ARM Cortex-A/M cores, baseband processors, and RF transceivers in smartphones. |
| Switching Frequency | 2.25 MHz (±12.5%) - enables use of 2.2-μH inductors and 10-μF ceramic capacitors, reducing solution footprint to < 15 mm². |
| Quiescent Current | 15 μA in PFM mode (MODE = GND, no load) - extends battery runtime during standby or deep-sleep states. |
| Efficiency Peak | Up to 96% at 3.6 VIN/1.8 VOUT/500 mA - minimizes thermal dissipation in thermally constrained handheld enclosures. |
| Thermal Resistance | RθJA = 67.8°C/W (DRV package) - enables 1-A operation without forced airflow in typical PCB layouts with 2 oz copper and thermal pad grounding. |
Pinout & Package
TPS62293DRVR uses a 2.0 mm × 2.0 mm × 0.8 mm WSON-6 (DRV) package with exposed thermal pad soldered to PCB ground plane for enhanced thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Power input | Accepts 2.3–6.0 V; requires local 10-μF ceramic decoupling; connects to battery or intermediate rail. |
| GND | Power ground | Primary return path for input/output currents; must be low-impedance connection to thermal pad. |
| EN | Enable control | Active-high logic input; pulling low disables device and reduces supply current to ≤1 μA. |
| FB | Feedback node | Internally tied to fixed 1.8-V divider; no external resistors required - simplifies layout and improves accuracy. |
| SW | Switch node | Drives external 2.2-μH inductor; high dv/dt node requiring tight loop area and guard ring to minimize EMI. |
| MODE | Operating mode select | Low = auto PFM/PWM transition; high = forced 2.25-MHz PWM - critical for EMI filtering or deterministic timing. |
Key Features
| Feature | Design Value |
|---|---|
| Dynamic voltage positioning | Maintains +1% output offset in PFM mode to reduce load-step undershoot/overshoot - improves stability for burst-mode processors. |
| 100% duty-cycle operation | Enables regulation down to VIN ≈ VOUT + IOUT×(RDS(on) + RL) - maximizes usable battery capacity in portable devices. |
| Integrated MOSFETs | High-side RDS(on) = 240–480 mΩ, low-side = 185–380 mΩ - eliminates external FETs and gate drivers, reducing component count. |
| Soft-start ramp time | 250 μs (5%→95% VOUT) - limits inrush current and prevents input rail collapse during power-up from weak sources. |
| Undervoltage lockout | 1.85 V (falling) / 1.95 V (rising) - prevents brownout operation and excessive battery discharge below safe cutoff. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62291DRVR | Fixed 3.3 V output; identical pinout, package, and electrical specs except VOUT and FB configuration. | Used where higher I/O voltage is required (e.g., legacy interfaces, 3.3-V sensors); not substitutable without board revision. | Select when system requires 3.3 V instead of 1.8 V - same layout, same thermal design, only output voltage differs. |
| TPS62067QDSGRQ1 | AEC-Q100 qualified automotive grade; 1.2-V to 5.5-V input; 3-MHz switching; 1.2-A max; different pinout (6-pin WSON but non-compatible). | Targeted for automotive infotainment and ADAS domains requiring qualification and wider temp range (–40°C to 125°C). | Choose for automotive applications needing qualification and higher current; not pin-compatible - requires layout change. |
Compared with TPS62293DRVR, TPS62291DRVR offers identical form-factor and efficiency but targets 3.3-V systems, while TPS62067QDSGRQ1 provides automotive qualification and higher current at the cost of non-interchangeable pinout and increased design validation effort.

FAQ
What is the output voltage of the TPS62293DRVR and is it adjustable?
The TPS62293DRVR provides a fixed 1.8 V output voltage with ±1.5% accuracy in PWM mode. It is not adjustable - the FB pin is internally connected to a precision resistor divider, eliminating external feedback components and ensuring consistent regulation without calibration or layout sensitivity.
Does the TPS62293DRVR require external feedback resistors?
No, the TPS62293DRVR does not require external feedback resistors. As a fixed-output variant, it integrates an internal resistor network connecting FB to GND and VIN, configured for 1.8 V. This simplifies design, reduces component count, and improves output voltage accuracy versus adjustable counterparts like the TPS62290DRVR.
How does the MODE pin affect operation of the TPS62293DRVR?
The MODE pin on the TPS62293DRVR selects between two operating modes: when pulled low (GND), it enables automatic PFM/PWM transition for peak efficiency across load range; when pulled high (VIN), it forces fixed 2.25-MHz PWM operation - essential for EMI-sensitive applications where deterministic switching frequency aids filtering and compliance testing.
What thermal performance can be expected from the TPS62293DRVR in its DRV package?
The TPS62293DRVR in the 2-mm × 2-mm WSON-6 (DRV) package has a junction-to-ambient thermal resistance (RθJA) of 67.8°C/W under standard JEDEC conditions. With proper PCB layout - including soldered exposed thermal pad to solid ground plane - it sustains 1-A continuous output at 85°C ambient without derating.
Is the TPS62293DRVR suitable for automotive applications?
The TPS62293DRVR is not AEC-Q100 qualified and is rated for –40°C to +85°C ambient operation - making it suitable for consumer and industrial portable equipment but not for under-hood or safety-critical automotive systems. For automotive use, consider the pin-compatible but qualified TPS62067QDSGRQ1 instead.
