TPS56921PWPR Description

Short technical summary and product information.

The TPS56921PWPR from Texas Instruments is a highly integrated, 9A synchronous step-down (buck) converter optimized for compact designs. It operates with an input voltage range of 4.5V to 17V and features VID control via an I2C compatible interface for adjustable output voltage.

 

Key electrical specifications include a 9A output current capability, switching frequencies from 200kHz to 1.6MHz, and integrated 26mΩ/19mΩ MOSFETs. The device offers precise voltage regulation with ±1.5% output voltage tolerance over temperature for VID control and ±1% for external regulation mode.

 

This converter is housed in a thermally enhanced 20-pin HTSSOP package with PowerPAD™ technology, suitable for surface mount applications. The operating temperature range is -40°C to 125°C (TJ), making it suitable for various environmental conditions. It includes features like monotonic start-up into pre-biased output, overcurrent protection with hiccup mode, thermal and overvoltage protection, and a power good monitor.
