The TPS62040 from Texas Instruments is a high-efficiency synchronous step-down DC-DC converter designed for battery-powered portable applications. It is optimized for use with single Li-Ion or 3-cell NiMH/NiCd batteries, supporting an input voltage range of 2.5V to 6.0V and an output voltage range from 0.7V to 6.0V.
This converter features a load current capability of up to 1.2A and operates at a fixed switching frequency of 1.25MHz. It achieves up to 95% conversion efficiency and maintains high efficiency across a wide load current range through its power-save mode operation at light loads. The TPS62040 also includes features such as 100% duty cycle for lowest dropout, internal softstart, dynamic output voltage positioning, thermal shutdown, and short-circuit protection.
Available in a 10-pin MSOP PowerPad package and a 10-pin QFN 3x3mm package, the TPS62040 is suitable for applications like PDAs, Pocket PCs, smartphones, USB powered modems, CPUs, DSPs, PC cards, notebooks, and xDSL applications. It supports standard 5V to 3.3V conversion.
Key electrical characteristics include a typical quiescent current of 18 µA and a maximum duty cycle of 100%. The operating temperature range is from -40°C to 85°C.
