The TPS62220DDCT from Texas Instruments is a high-efficiency synchronous step-down converter designed for portable applications. It supports an input voltage range of 2.5V to 6V, making it suitable for systems powered by 1-cell Li-Ion or 3-cell NiMH/NiCd batteries, as well as standard 3.3V or 5V rails.
This converter can deliver up to 400mA of output current with an adjustable output voltage ranging from 0.7V to 6V. It operates at a fixed switching frequency of 1.25MHz, achieving up to 95% efficiency under nominal load conditions. At light loads, it enters a power-save mode, reducing the switching frequency and quiescent current to typically 15 μA, further enhancing efficiency.
The TPS62220DDCT is available in a compact TSOT-23 package, enabling small system solutions. Its design features include 100% duty cycle low-dropout operation and soft start.
Key electrical specifications include an input voltage range of 2.5V to 6V, an output voltage range of 0.7V to 6V, and a maximum output current of 400mA. The device operates at a fixed 1.25MHz switching frequency and boasts high efficiency over a wide load range.
