TPS62227DDCR Description

Short technical summary and product information.

The Texas Instruments TPS62227DDCR is a synchronous step-down (buck) converter designed for portable systems. It offers high efficiency, reaching up to 95%, and can deliver up to 400mA of output current.

 

This device operates with a fixed 1.25MHz switching frequency, contributing to its efficiency over a wide load current range. It features a fixed output voltage of 1.2V and accepts an input voltage range from 2.5V to 6V, making it suitable for battery-powered applications using 1-cell Li-Ion or 3-cell NiMH/NiCd batteries, as well as standard 3.3V or 5V rails.

 

The TPS62227DDCR is available in a compact SOT-23-5 Thin package, enabling small system solutions. Its design includes features like 100% duty cycle operation and low quiescent current, typically 15 μA in power-save mode, which is beneficial for extending battery life in light load conditions.

 

Applications for this converter include power supplies for processors in PDAs, pocket PCs, smart phones, digital cameras, and portable media players. Its synchronous rectification ensures high efficiency, and the small external component count, combined with the tiny package, minimizes board space.
