The Texas Instruments TPS54540DDAR is a step-down DC-DC converter designed for efficient power management. It operates with an input voltage range from 4.5V to 42V and can deliver up to 5A of output current. The device supports an adjustable output voltage, with a minimum of 0.8V and a maximum of 41.1V, providing flexibility for various applications.
This converter utilizes a buck topology and operates at a switching frequency adjustable between 100kHz and 2.5MHz. It features a low quiescent current of 146 µA and a shutdown current of 2 µA, contributing to power efficiency, especially at light loads with its Eco-mode™ capability. The operating temperature range is from -40°C to 150°C (TJ).
The TPS54540DDAR is housed in an 8-pin SO PowerPad package, suitable for surface mounting. This package type, along with its specifications, makes it a robust choice for designs requiring reliable voltage regulation in a compact form factor. Key features include over-current protection and adjustable UVLO voltage.
