Product details
Overview
TPS62242DRVR from Texas Instruments is a synchronous step-down DC-DC converter in a 2-mm × 2-mm WSON-6 package, delivering up to 300 mA output current with fixed 1.2 V output, 2.25-MHz switching frequency, and >94% peak efficiency at 3.6 V input. It operates across 2 V–6 V input range and supports Li-ion, alkaline, and 3.3 V/5 V rails in space-constrained portable power rails.
For engineers reviewing the TPS62242DRVR datasheet, TPS62242DRVR pinout, TPS62242DRVR application, or TPS62242DRVR equivalent, key selection considerations include its 1.2 V fixed output, MODE-pin-selectable PWM/PSM operation, 15 μA quiescent current in PFM mode, thermal shutdown at 140°C, and compatibility with 2.2 μH inductors and 10 μF ceramic output capacitors.
Technical Context
The TPS62242DRVR uses voltage-mode control with input-voltage feed-forward for fast line/load regulation and stable operation with small ceramic capacitors. Its internal 0.6 V reference and fixed-resistor feedback network set the 1.2 V output without external divider components.
It implements automatic transition between 2.25-MHz PWM mode (moderate/heavy load) and pulse-frequency modulation (PFM) mode (light load), with MODE pin forcing fixed-frequency operation when pulled high. The integrated high-side (480 mΩ max) and low-side (380 mΩ max) MOSFETs enable synchronous rectification and 100% duty-cycle dropout operation near VIN ≈ VOUT.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.2 V ±1.5% in PWM mode - eliminates need for external feedback resistors and simplifies layout. |
| Input Voltage Range | 2 V to 6 V - supports single-cell Li-ion (2.7–4.2 V), two/three-cell alkaline, and standard 3.3 V/5 V rails. |
| Max Output Current | 300 mA - sufficient for baseband processors, RF transceivers, and low-power DSPs in handheld devices. |
| Switching Frequency | 2.25 MHz (±12.5%) - enables use of compact 2.2 μH inductors and <1-mm solution height. |
| Quiescent Current | 15 μA typical in PFM mode - extends battery life in standby/sleep states of portable electronics. |
| Shutdown Current | 0.1–1 μA - ensures minimal battery drain when EN = GND in system-level power gating. |
| UVLO Threshold | 1.85 V (falling), 1.95 V (rising) - prevents brownout operation and protects battery from deep discharge. |
| Thermal Shutdown | 140°C with 20°C hysteresis - safeguards against sustained overload or poor PCB thermal design. |
Pinout & Package
TPS62242DRVR is housed in a thermally enhanced 6-pin WSON package (2.00 mm × 2.00 mm × 0.80 mm) with exposed thermal pad (Pin 6 = GND). The package supports high-density layouts and efficient heat dissipation via PCB copper area under the pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 5) | Power input supply | Accepts 2–6 V; requires local 4.7 μF ceramic decoupling close to pin to suppress switching noise. |
| GND (Pin 6) | Ground reference & thermal pad | Primary return path for power and signal; must be connected to large PCB ground plane for thermal and EMI performance. |
| EN (Pin 4) | Enable control input | Active-high logic; pull high ≥1 V to enable, pull low ≤0.4 V to enter <1 μA shutdown - used for power sequencing. |
| FB (Pin 3) | Feedback input | Internally connected to fixed 1.2 V divider; externally tied directly to output capacitor - no external resistors needed. |
| SW (Pin 1) | Power switch node | Connects to inductor; carries high di/dt switching current - requires short, wide trace and ground guard ring to minimize EMI. |
| MODE (Pin 2) | Operation mode select | Pull to GND for automatic PWM↔PFM transition; pull to VIN for forced fixed-frequency PWM - critical for noise-sensitive analog sections. |
Key Features
| Feature | Design Value |
|---|---|
| High-efficiency synchronous conversion | >94% peak efficiency at 3.6 V/150 mA - reduces thermal load and extends runtime in battery-powered systems. |
| Ultra-small solution size | Supports <1-mm profile with 2.2 μH inductor and 0603-case 10 μF output capacitor - ideal for slim mobile form factors. |
| Fast transient response | Voltage-mode control with feed-forward enables rapid correction of load steps without external compensation. |
| Low-noise PFM/PWM dual-mode operation | PFM minimizes quiescent current at light loads; PWM ensures predictable EMI spectrum when MODE = VIN. |
| Robust protection suite | Integrated thermal shutdown, undervoltage lockout, and cycle-by-cycle current limiting on both high- and low-side switches. |
| 100% duty-cycle low-dropout mode | Maintains regulation down to VIN ≈ VOUT + IOUT×RDS(on) - extracts maximum energy from depleting batteries. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62240DRVR | Adjustable output (0.6–VIN) via external resistor divider; same package, pinout, and specs otherwise. | Requires two external resistors and layout space; suited for multi-rail designs needing flexibility. | Select TPS62240DRVR only if variable output voltage is required; TPS62242DRVR saves BOM cost and board area for fixed 1.2 V. |
| TPS62260DRVR | Higher 600 mA output, 2.5 MHz switching, improved light-load efficiency (12 μA), but wider 2.3–6.5 V input range. | Not suitable for 2.0–2.3 V inputs; larger inductor footprint due to higher current rating. | Choose TPS62260DRVR only when >300 mA load or tighter light-load efficiency is mandatory; TPS62242DRVR better matches 300 mA, 2 V start-up needs. |
Compared with TPS62240DRVR and TPS62260DRVR, the TPS62242DRVR offers optimal balance of fixed 1.2 V simplicity, 2 V minimum input support, and ultra-compact 2×2 mm footprint - making it the preferred choice for cost- and space-sensitive 300 mA portable power rails.

FAQ
What is the output voltage of the TPS62242DRVR and is it adjustable?
The TPS62242DRVR provides a fixed 1.2 V output voltage with ±1.5% accuracy in PWM mode. It is not adjustable - the internal resistor divider is factory-trimmed for 1.2 V, and the FB pin is internally connected to this network. Unlike the TPS62240DRVR, no external resistors are required or supported for voltage setting on the TPS62242DRVR.
Does the TPS62242DRVR require an external feedback resistor network?
No, the TPS62242DRVR does not require an external feedback resistor network. Its 1.2 V output is set by an internal precision divider tied to the 0.6 V reference. The FB pin is internally connected and must be routed directly to the output capacitor's VOUT node - no external resistors or compensation components are needed.
What package type and dimensions does the TPS62242DRVR use?
The TPS62242DRVR uses the DRV package: a 6-pin WSON (Wafer-Level Small Outline No-lead) measuring 2.00 mm × 2.00 mm × 0.80 mm with an exposed thermal pad (Pin 6). This package enables high-density placement and efficient thermal transfer to the PCB ground plane.
How does the MODE pin affect operation of the TPS62242DRVR?
The MODE pin on the TPS62242DRVR selects between two operating modes: when pulled low (GND), it enables automatic PWM↔PFM transition for highest light-load efficiency; when pulled high (VIN), it forces fixed-frequency 2.25-MHz PWM operation - essential for EMI-sensitive applications like RF receivers or audio circuits.
What is the minimum input voltage required for the TPS62242DRVR to maintain regulation?
The TPS62242DRVR maintains regulation down to approximately 1.4 V under light load due to its 100% duty-cycle capability, but the recommended minimum input is 2.0 V per datasheet specifications. Below 2.0 V, UVLO activates (threshold ~1.85 V falling), disabling the device to protect the battery and ensure stable startup.
