TPS54320RHLR Description

Short technical summary and product information.

The Texas Instruments TPS54320RHLR is an active synchronous step-down SWIFT converter designed for efficient power management. It supports an input voltage range from 4.5V to 17V and can deliver up to 3A of output current.

 

This converter features an adjustable output voltage, with a minimum output voltage of 0.8V and a maximum of 15V. It operates with a switching frequency adjustable from 200kHz to 1.2MHz, allowing for flexibility in design. The device includes integrated 57mΩ and 50mΩ MOSFETs for high-side and low-side switching, respectively.

 

Key features include a low shutdown quiescent current of 2µA, a voltage reference with ±1% accuracy, and hiccup overcurrent protection. The TPS54320RHLR is housed in a 14-VQFN package with a 3.5mm x 3.5mm footprint, suitable for surface mounting. Its operating temperature range is -40°C to 150°C (TJ).

 

This component is pin-to-pin compatible with the TPS54620 and supports features like frequency synchronization, power good output, and monotonic start-up into prebiased outputs. It is supported by TI's WEBENCH Power Designer tool for custom design.
