TPS54821RHLT Description

Short technical summary and product information.

The Texas Instruments TPS54821RHLT is an 8A synchronous buck converter designed for efficient power management. It accepts an input voltage from 4.5V to 17V and provides an adjustable output voltage down to 0.6V.

 

Key electrical specifications include a maximum output current of 8A and a switching frequency that can be adjusted from 200 kHz to 1.6 MHz. The device features integrated 26 mΩ and 19 mΩ MOSFETs for high-side and low-side switching, respectively. It operates within a temperature range of -40°C to 125°C.

 

This converter supports various features such as Enable, Forced PWM, Frequency synchronization, Power good output, Prebias startup, and adjustable Soft-start. It also includes synchronous rectification for improved efficiency. The device is housed in a 14-VQFN package measuring 3.5 mm x 3.5 mm, with an exposed pad for enhanced thermal performance.

 

The TPS54821RHLT is suitable for applications requiring a compact and efficient step-down voltage conversion solution. Its adjustable output and wide operating parameters make it versatile for different design needs.
