Texas Instruments TPS62262DRVR

Overview

TPS62262DRVR from Texas Instruments is a 2.25-MHz synchronous step-down DC/DC converter delivering up to 600 mA output current from 2 V to 6 V input, with fixed 1.2 V output, 15-μA quiescent current in power-save mode, and 2.25-MHz fixed-frequency PWM operation-designed for Li-ion battery-powered mobile phones and portable media players.

For engineers reviewing the TPS62262DRVR datasheet, TPS62262DRVR pinout, TPS62262DRVR application, or TPS62262DRVR equivalent, key selection criteria include its 1.2 V fixed output, WSON-6 package with MODE pin for PFM/PWM control, ±1.5% output voltage accuracy in PWM mode, and support for <1-mm solution height in space-constrained designs.

Technical Context

The TPS62262DRVR employs voltage-mode control with input voltage feed-forward for fast line/load regulation and uses internal high-side (480 mΩ max) and low-side (380 mΩ max) MOSFETs. Its 2.25-MHz oscillator enables small external components, while dynamic voltage positioning raises output by +1% in PFM mode to minimize load-step undershoot.

It supports three functional modes: forced PWM (MODE = VIN), automatic PFM/PWM transition (MODE = GND), and shutdown (EN = GND). Undervoltage lockout activates at 1.85 V (falling), and thermal shutdown engages at 140°C with 20°C hysteresis-ensuring robust operation across –40°C to 85°C ambient.

Key Specifications

Pinout & Package

FAQ

What is the output voltage of the TPS62262DRVR?

The TPS62262DRVR provides a fixed 1.2 V output voltage. This is factory-trimmed and does not require external feedback resistors. The device achieves ±1.5% accuracy in PWM mode across temperature and load, making it suitable for powering core logic rails in microprocessors and FPGAs. The TPS62262DRVR's internal reference is 600 mV, and the fixed divider ratio sets the regulated output precisely to 1.2 V.

Does the TPS62262DRVR support power-save mode?

Yes, the TPS62262DRVR supports automatic power-save mode (PFM) when the MODE pin is pulled low (to GND). In this mode, it reduces quiescent current to 15 μA at no load while maintaining +1% dynamic voltage positioning for improved transient response. The TPS62262DRVR transitions seamlessly between PFM and 2.25-MHz PWM based on load demand-enabling high efficiency across the full 0–600 mA range without manual intervention.

What package type does the TPS62262DRVR use?

The TPS62262DRVR uses a 6-pin WSON package (DRV designation) measuring 2.00 mm × 2.00 mm × 0.8 mm with an exposed thermal pad (Pin 6). This compact, thermally enhanced package supports <1-mm solution height and is optimized for high-density portable PCBs. Unlike the SOT-5 variants in the same family, the TPS62262DRVR's WSON package includes the MODE pin and delivers superior thermal performance (RθJA = 67.8°C/W).

Can the TPS62262DRVR operate from a single Li-ion cell?

Yes, the TPS62262DRVR operates from a single Li-ion cell across its full discharge curve (2.0 V to 4.2 V nominal). Its 2 V minimum input rating, 100% duty-cycle capability, and low dropout behavior allow regulation down to ~1.4 V input at light loads. The TPS62262DRVR maintains 1.2 V output with ±1.5% accuracy throughout this range, making it ideal for battery-powered applications where maximum energy extraction is critical.

How does the MODE pin affect TPS62262DRVR operation?

The MODE pin on the TPS62262DRVR selects between two operating modes: pulling MODE low (GND) enables automatic PFM/PWM transition for peak efficiency; pulling MODE high (VIN) forces fixed-frequency 2.25-MHz PWM operation-even at light loads-for predictable EMI filtering and reduced output ripple. This dual-mode flexibility makes the TPS62262DRVR adaptable to both noise-sensitive and battery-life-critical subsystems within the same design.
