The Texas Instruments TPS54521RHLT is a versatile synchronous step-down (buck) converter designed for efficient power management in compact applications. It supports an input voltage range from 1.6V to 17V and can deliver up to 5A of output current.
Key electrical specifications include a wide switching frequency range of 200kHz to 900kHz, an integrated voltage reference of 0.8V, and low shutdown quiescent current of 2μA. The device features integrated 57mΩ and 50mΩ MOSFETs for high-side and low-side operation, respectively. It offers an adjustable output voltage and a positive output configuration.
Operating within a junction temperature range of -40°C to 125°C, the TPS54521RHLT is housed in a 14-VQFN package with an exposed pad, suitable for surface mounting. The package dimensions are 3.5mm x 3.5mm. It is supplied on tape and reel with a standard package quantity of 250 units.
This converter is well-suited for applications such as flat panel digital TVs, set-top boxes, personal video recorders, and netbooks requiring high-density power distribution from a 12V bus.
