Texas Instruments TPS62263DRVR

Overview

TPS62263DRVR 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 2.5 V output voltage, 1.5% PWM-mode accuracy, and 15-μA quiescent current in power-save mode - used for low-power DSP supply and portable media player core rails.

For engineers reviewing the TPS62263DRVR datasheet, TPS62263DRVR pinout, TPS62263DRVR application, or TPS62263DRVR equivalent, key selection criteria include fixed-output voltage configuration, WSON-6 package compatibility, MODE-pin controllable PWM/PSM transition, thermal shutdown at 140°C, and support for Li-ion battery discharge down to 2 V with 100% duty cycle operation.

Technical Context

The TPS62263DRVR employs voltage-mode control with input voltage feed-forward for fast line/load regulation and operates at a fixed 2.25 MHz switching frequency in PWM mode; its internal 0.6-V reference and integrated resistor divider set nominal 2.5 V output without external feedback components.

It features automatic PFM/PWM mode transition controlled by the MODE pin: pulled low (GND) enables power-save mode with dynamic voltage positioning (+1% light-load bias), while pulled high forces continuous PWM for noise-sensitive applications - both modes retain undervoltage lockout (1.85 V falling threshold) and thermal shutdown (140°C, 20°C hysteresis).

FAQ

What output voltage does the TPS62263DRVR provide?

The TPS62263DRVR provides a fixed 2.5 V output voltage with ±1.5% accuracy in PWM mode. Its internal resistor divider eliminates the need for external feedback components, simplifying design and reducing bill-of-materials cost. This fixed output is factory-trimmed and does not require adjustment - the FB pin must be connected directly to the output capacitor.

Does the TPS62263DRVR support power-save mode, and how is it enabled?

Yes, the TPS62263DRVR supports automatic power-save mode (PFM) at light loads. It is enabled by pulling the MODE pin to GND. In this state, the device reduces switching frequency and achieves 15-μA quiescent current while maintaining +1% dynamic voltage positioning to minimize load-step undershoot. The transition between PFM and PWM occurs seamlessly based on output current demand.

What package type and thermal characteristics does the TPS62263DRVR use?

The TPS62263DRVR uses a 6-pin 2 mm × 2 mm × 0.8 mm WSON package (DRV suffix) with an exposed thermal pad (Pin 6). Its junction-to-ambient thermal resistance (RθJA) is 67.8°C/W, and junction-to-board (RθJB) is 37.2°C/W - enabling >500 mA continuous output at TA = 85°C with standard 2-layer PCB copper pour under the thermal pad.

Can the TPS62263DRVR operate from a single Li-ion battery throughout its full discharge curve?

Yes, the TPS62263DRVR supports input voltages from 2 V to 6 V and enters 100% duty cycle mode as VIN approaches VOUT, sustaining regulation down to ~2.5 V at full load. Its undervoltage lockout (UVLO) disables operation below 1.85 V (falling), protecting the battery from over-discharge while maximizing usable capacity.

How does the TPS62263DRVR handle short-circuit conditions?

The TPS62263DRVR incorporates cycle-by-cycle current limiting on both high-side and low-side MOSFETs, with a typical forward current limit (ILIMF) of 1 A. During overload, the device clamps peak inductor current, disables switching after fault detection, and automatically recovers once the short is removed - no latch-off or external circuitry required.
