TPS62222DDCRG4 Description

Short technical summary and product information.

The TPS62222DDCRG4 from Texas Instruments is a high-efficiency synchronous step-down (buck) converter designed for portable systems. It features a wide input voltage range from 2.5V to 6V, making it suitable for various power sources including 1-cell Li-Ion or 3-cell NiMH/NiCd batteries, as well as standard 3.3V or 5V rails.

 

This converter delivers a fixed output voltage of 1.8V with a maximum output current of 400mA. It operates at a fixed switching frequency of 1.25MHz, contributing to its high efficiency of up to 95%. The device also boasts a low quiescent current of typically 15 μA during light load conditions due to its power-save mode.

 

Key features include soft start, 100% duty cycle low-dropout operation, and dynamic output-voltage positioning. The TPS62222DDCRG4 is available in a compact SOT-23-5 Thin package, enabling small system solutions. Its applications include PDAs, cellular phones, smart phones, digital cameras, and portable media players.
