LM2591HVSX-ADJ Description

Short technical summary and product information.

The Texas Instruments LM2591HVSX-ADJ is a monolithic integrated circuit designed for step-down (buck) switching regulator applications. It is capable of driving a 1A load with excellent line and load regulation. This device features an adjustable output voltage range from 1.2V to 57V, with a maximum deviation of ±4% over line and load conditions.

 

Operating at a fixed switching frequency of 150kHz, the LM2591HVSX-ADJ allows for the use of smaller filter components compared to lower-frequency regulators. It includes essential protection features such as thermal shutdown and current-limit protection, enhancing its reliability in various applications. The regulator is available in a 5-pin TO-263 package, suitable for surface mount applications.

 

Key electrical characteristics include an input voltage range up to 60V and a typical quiescent current of 90μA in standby mode. The device also features ON/OFF control for power management. Its design simplifies the implementation of efficient switching regulators on a circuit board.
