TPS56221DQPT Description

Short technical summary and product information.

The TPS56221DQPT from Texas Instruments is a synchronous SWIFT™ buck converter. It is designed to provide a high-current output of up to 25A, making it suitable for demanding power applications. The device accepts an input voltage ranging from 4.5V to 14V and offers an adjustable output voltage from 0.6V to 12V.

 

Key features include adjustable current limit, enable functionality, forced PWM mode, overcurrent protection, and power good indication. It also incorporates prebias startup and adjustable soft-start capabilities. The converter operates in voltage mode with feed-forward and utilizes synchronous rectification for improved efficiency. Its fixed switching frequency options include 300 kHz, 500 kHz, and 1 MHz.

 

The TPS56221DQPT is housed in a 22-pin 5mm x 6mm PQFN PowerPAD™ package, designed for surface mounting. This package type, along with its integrated power block technology and R DS(on) sensing for high-side and low-side MOSFETs, contributes to a compact solution size. The operating temperature range is -40°C to 125°C (TJ).
