TPS627451DSSR Description

Short technical summary and product information.

The TPS627451DSSR from Texas Instruments is a highly efficient, ultra-low quiescent current synchronous step-down converter designed for low-power wireless applications. It features an input voltage range from 3.3V to 10V and supports selectable output voltages from 1.3V to 2.8V, with a maximum output current of 300mA.

 

This converter boasts a typical quiescent current of only 400 nA, making it ideal for battery-powered devices. It achieves up to 90% efficiency with load currents greater than 15 µA and operates at frequencies up to 2.5MHz. Key features include adaptive voltage scaling, an enable pin, light-load efficiency optimization, an output discharge function, and a power good output.

 

The TPS627451DSSR is housed in a compact 12-WSON (2mm x 3mm) package, suitable for space-constrained designs. Its control mode utilizes Constant on-time (COT) and DCS-Control for stable operation. The operating temperature range is -40°C to 125°C (TA).

 

This device is well-suited for applications requiring minimal power consumption, such as IoT devices, portable electronics, and wireless sensor nodes. Its RF-friendly design and low output ripple voltage further enhance its suitability for sensitive applications.
