TPS61240DRVT

The Texas Instruments TPS61240DRVT is a high-efficiency step-up (boost) converter IC. It is designed to provide a stable 5V output voltage with an output current capability of up to 450mA, drawing from an input voltage range of 2.3V to 5.5V.

Key electrical characteristics include a typical switching frequency of 3.5MHz, a low quiescent current of 30µA, and an efficiency exceeding 90% under nominal operating conditions. The device features synchronous rectification for improved efficiency and a switch current limit of 0.6A. The output voltage accuracy is typically ±2% of the 5.0V nominal output.

This boost converter is available in a 6-WSON (2x2 mm) package, requiring surface mount assembly. The compact package and the need for only three external components (one inductor, two ceramic capacitors) contribute to a small total solution size, making it suitable for space-constrained designs. It also includes features like load disconnect during shutdown, current overload protection, and thermal shutdown protection.

The TPS61240DRVT is suitable for various power management applications where a higher output voltage is needed from a lower input voltage source, such as battery-powered devices and portable electronics.
