The Texas Instruments TPS53819ARGTR is a high-performance synchronous buck controller featuring D-CAP2 mode for fast transient response and PMBus interface for control and monitoring. This controller is designed to handle up to 40A of output current, with an input voltage range from 3V to 28V and an adjustable output voltage from 0.6V to 5.5V.
Key features include adjustable current limit, dynamic voltage scaling, power good indication, and pre-bias start-up. The device supports auto-skip Eco-mode for improved light-load efficiency and adaptive on-time control with selectable frequencies via PMBus. It also offers programmable soft-start, power-on delay, and VDD UVLO levels.
The TPS53819ARGTR is housed in a compact 16-pin VQFN package measuring 3mm x 3mm. Its surface mount type and operating temperature range of -40°C to 85°C make it suitable for various demanding applications. The controller integrates internal protections against overvoltage, undervoltage, and overcurrent conditions, along with thermal shutdown for enhanced reliability.
