The Texas Instruments TPS54821RHLR is a highly integrated synchronous buck converter capable of delivering up to 8A of output current. It is designed to operate from an input voltage range of 4.5V to 17V, making it suitable for a variety of power supply applications.
Key electrical specifications include an adjustable output voltage from 0.6V to 15V, a switching frequency that can be set between 200kHz and 1.6MHz, and a typical quiescent current of 0.6mA. The device features integrated 26 mΩ and 19 mΩ MOSFETs for high-side and low-side switching, respectively. It also includes features such as Enable, Forced PWM, Frequency synchronization, Power good, Prebias startup, Soft-start adjustable, Synchronous rectification, and Tracking.
The TPS54821RHLR is housed in a 14-VQFN (3.5x3.5 mm) package with an exposed pad for enhanced thermal performance. The operating temperature range is -40°C to 125°C (TJ). This component is suitable for applications requiring efficient step-down voltage conversion with precise control and monitoring capabilities.
