LM2593HVS-ADJ Description

Short technical summary and product information.

The LM2593HVS-ADJ from Texas Instruments is a versatile 2A step-down (buck) switching voltage regulator. It offers an adjustable output voltage that can be set anywhere between 1.2V and 57V, with a typical accuracy of ±4% over line and load conditions. The device accepts a wide input voltage range from 4.5V to 60V, making it suitable for various power supply applications.

 

This regulator operates at a fixed switching frequency of 150kHz, which helps in reducing the size of external components like inductors and capacitors. It includes features such as over-current protection and a power good signal. The LM2593HVS-ADJ is available in a TO-263-7 surface-mount package, designed for efficient thermal management.

 

With a typical quiescent current of 5mA and a low power standby mode current of 90µA, this component is designed for power efficiency. The operating temperature range is -40°C to 125°C (TJ), ensuring reliable performance in demanding environments. Its voltage mode control and lack of synchronous rectification are key electrical characteristics for designers to consider.
