TPS54620RGYR

The Texas Instruments TPS54620RGYR is an active synchronous SWIFT™ buck converter designed for efficient power management. It features a wide input voltage range of 4.5V to 17V and can deliver up to 6A of output current. The output voltage is adjustable from 0.8V to 15V, offering flexibility for various applications.

Key electrical specifications include a switching frequency range of 200kHz to 1.6MHz, enabling optimized performance and component size. The integrated MOSFETs have typical on-resistances of 26 mΩ for the high-side and 19 mΩ for the low-side. It also includes features like Enable, Frequency synchronization, Power good, Pre-Bias Start-Up, and Soft Start.

This converter operates within a junction temperature range of -40°C to 150°C, making it suitable for demanding environments. It is available in a 14-VQFN package with a surface mount type. The low shutdown quiescent current of 2µA contributes to power efficiency in standby modes.

Additional features include a ±1% voltage reference, adjustable input undervoltage lockout, and monotonic start-up into prebiased outputs. The device also offers overtemperature protection and a power good output monitor for undervoltage and overvoltage conditions.
