TPS62740DSSR Description

Short technical summary and product information.

The TPS62740DSSR from Texas Instruments is a highly efficient step-down buck converter designed for low-power applications. It features an ultra-low quiescent current of 360nA, enabling extended battery life in portable devices.

 

This converter supports an input voltage range from 2.2V to 5.5V and can deliver up to 300mA of output current. It achieves up to 90% efficiency at low loads, making it suitable for power-sensitive designs. The device operates at a switching frequency of up to 2 MHz, allowing for the use of small external components.

 

The TPS62740DSSR is housed in a compact 12-WSON package, measuring 2x3 mm, which facilitates a small total solution size of less than 31mm². It offers 16 selectable output voltages in 100mV steps between 1.8V and 3.3V. The operating temperature range is -40°C to 85°C.

 

This converter is optimized for operation with a tiny 2.2µH inductor and a 10µF output capacitor. Its features include DCS-Control™ for high efficiency and RF-friendly operation, a power good output, and a slew rate controlled load switch discharge function.
