TPS56921PWP Description

Short technical summary and product information.

The Texas Instruments TPS56921PWP is an obsolete synchronous buck converter designed for step-down power conversion. It features a wide input voltage range of 4.5V to 17V and can deliver a maximum output current of 9A. The output voltage is adjustable, ranging from 0.72V to 1.48V, with precise control via an I2C compatible interface.

 

Key electrical specifications include a switching frequency adjustable from 200kHz to 1.6MHz, integrated 26mΩ and 19mΩ MOSFETs, and a low quiescent current of 0.77mA typical. The converter includes features such as soft start, power good monitoring, overcurrent protection, and thermal shutdown.

 

This device is housed in a 20-pin HTSSOP package with a PowerPAD, suitable for surface mount applications. The operating temperature range is -40°C to 125°C (TJ). Its design incorporates adaptive voltage scaling and synchronous rectification for improved efficiency.

 

Due to its obsolete status, engineers should consider alternative solutions for new designs. However, for existing systems, the TPS56921PWP offers robust performance for power management applications requiring adjustable output voltages.
