Product details
Overview
TPS62242DRVT from Texas Instruments is a synchronous step-down DC-DC converter delivering up to 300 mA output current with fixed 1.2 V output, 2.25 MHz switching frequency, and input voltage range of 2 V to 6 V. It operates in power-save mode at light loads and supports Li-ion, alkaline, and 3.3 V/5 V rails in compact portable power supplies.
For engineers reviewing the TPS62242DRVT datasheet, TPS62242DRVT pinout, TPS62242DRVT application, or TPS62242DRVT equivalent, key selection considerations include its 1.2 V fixed output, WSON-6 package footprint, 15 μA quiescent current in PFM mode, 94%+ peak efficiency, and MODE pin-controlled PWM/PFM transition for noise-sensitive or battery-life-critical designs.
Technical Context
The TPS62242DRVT uses voltage-mode control with input-voltage feed-forward for fast line/load regulation and stable operation with small ceramic capacitors. Its dual-mode operation-fixed-frequency PWM (MODE = high) or automatic PFM/PWM transition (MODE = GND)-enables optimization between low-noise performance and light-load efficiency.
Internally, it integrates high-side and low-side MOSFETs with typical RDS(on) of 240 mΩ and 180 mΩ, respectively, and features undervoltage lockout (1.85 V falling threshold), thermal shutdown (140 °C), and soft-start (250 μs ramp-up). The 100% duty-cycle capability extends usable battery range down to VOUT + IOUT × RDS(on) + LDCR.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.2 V ±1.5% in PWM mode - ensures stable core supply for low-power DSPs and baseband processors. |
| Max Output Current | 300 mA - sufficient for Bluetooth headsets, WLAN transceivers, and portable media player subsystems. |
| Switching Frequency | 2.25 MHz (±12.5%) - enables use of tiny 2.2 µH inductors and <1-mm solution height. |
| Input Voltage Range | 2 V to 6 V - supports single-cell Li-ion (2.7–4.2 V), two/three-cell alkaline, and 3.3 V/5 V rails. |
| Quiescent Current | 15 µA (PFM mode, no load) - extends battery runtime in standby or idle states. |
| Shutdown Current | 0.1 µA - minimizes system leakage when powered off via EN pin. |
| Efficiency Peak | >94% at 3.6 VIN/1.2 VOUT/100 mA - reduces thermal load in sealed handheld enclosures. |
Pinout & Package
TPS62242DRVT 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 = GND). The package supports high-density layout and efficient PCB heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 5) | Power input | Accepts 2–6 V; requires local 4.7 µF ceramic decoupling close to pin for low-impedance path. |
| GND (Pin 6) | Ground reference & thermal pad | Must be connected to large PCB copper area for thermal management and noise reduction. |
| EN (Pin 4) | Enable control | Active-high logic; pulling low disables regulator and reduces current to 0.1 µA. |
| FB (Pin 3) | Feedback input | Internally connected to fixed 1.2 V divider; connect directly to output capacitor for regulation. |
| SW (Pin 1) | Switch node | Drives external 2.2 µH inductor; requires short, low-inductance trace to minimize EMI and ringing. |
| MODE (Pin 2) | Operation mode select | GND = auto PFM/PWM transition; VIN = forced fixed-frequency PWM for EMI control. |
Key Features
| Feature | Design Value |
|---|---|
| Power-save mode with PFM | Reduces quiescent current to 15 µA at light loads while maintaining regulation and low output ripple. |
| 2.25 MHz fixed-frequency PWM | Enables sub-1 mm solution height using 2.2 µH inductors and 0603/0805 MLCCs. |
| 100% duty-cycle low-dropout | Extends usable battery life by regulating down to VIN ≈ VOUT + IOUT×RDS(on) + LDCR. |
| Integrated MOSFETs | Eliminates external switch components; high-side RDS(on) = 240 mΩ, low-side = 180 mΩ @ 3.6 V. |
| Soft-start | Ramps output from 5% to 95% of 1.2 V in 250 µs, limiting inrush current and preventing input rail collapse. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62240DRVT | Adjustable output (0.6–VIN) via external resistor divider; identical package, pinout, and electrical specs otherwise. | Requires external FB resistors; suitable when multiple output voltages are needed on same PCB. | Select TPS62240DRVT only if adjustable output is required; TPS62242DRVT eliminates BOM and layout overhead for fixed 1.2 V. |
| TPS62260DRVR | Same family, 300 mA, 2.25 MHz, but in smaller 2-mm × 2-mm WSON-6 with improved 12 µA quiescent current and 1.8 V fixed output. | Not pin-compatible; requires redesign of feedback network and may need inductor/capacitor re-optimization. | Choose TPS62260DRVR only for new designs targeting lower IQ or 1.8 V output; TPS62242DRVT remains optimal for legacy 1.2 V systems. |
Compared with TPS62240DRVT, TPS62242DRVT removes external resistor dependencies and simplifies layout, while versus TPS62260DRVR it offers proven 1.2 V compatibility without footprint or control-loop changes-critical for cost-sensitive, high-volume portable designs.

FAQ
What is the output voltage tolerance of the TPS62242DRVT under PWM operation?
The TPS62242DRVT provides a fixed 1.2 V output with ±1.5% accuracy in PWM mode across temperature and line conditions. This specification is guaranteed over the full operating ambient temperature range (–40°C to 85°C) and input voltage range (2 V to 6 V), ensuring reliable core voltage delivery for precision analog and digital circuitry without external trimming.
Does the TPS62242DRVT require external feedback resistors?
No, the TPS62242DRVT does not require external feedback resistors. As a fixed-output variant, it integrates an internal resistor divider that connects the FB pin directly to the output capacitor. External resistors are only needed for adjustable versions like the TPS62240DRVT; using them with the TPS62242DRVT would disrupt regulation and is not supported.
How does the MODE pin affect efficiency and noise performance of the TPS62242DRVT?
When the MODE pin is pulled low (GND), the TPS62242DRVT enters power-save mode and automatically transitions between PFM and PWM to maximize light-load efficiency (15 µA IQ). When pulled high (VIN), it forces fixed-frequency PWM operation, which increases light-load IQ but delivers predictable 2.25 MHz switching for easier EMI filtering-making the TPS62242DRVT adaptable to both battery-life and noise-critical requirements.
What thermal performance can be expected from the TPS62242DRVT in a standard 2-layer PCB layout?
In a standard 2-layer PCB with 1-in² 1-oz copper pour connected to the exposed thermal pad (Pin 6), the TPS62242DRVT achieves a junction-to-ambient thermal resistance (RθJA) of 67.8°C/W. At 300 mA output and 3.6 V input, this yields ~20°C temperature rise above ambient-well within the –40°C to 125°C operating junction range and eliminating need for forced air cooling in handheld applications.
Is the TPS62242DRVT pin-compatible with other members of the TPS6224x family?
Yes, the TPS62242DRVT shares identical pin configuration, package dimensions (WSON-6, 2.0 mm × 2.0 mm), and pin functions with TPS62240DRVT and TPS62243DRVT. All three variants use the same VIN, GND, EN, FB, SW, and MODE pin assignments-allowing drop-in replacement for different output voltages (adjustable, 1.2 V, or 1.8 V) without layout changes.
