LM2575D2T-ADJG Description

Short technical summary and product information.

The ON Semiconductor LM2575D2T-ADJG is a monolithic integrated circuit designed for easy and convenient design of step-down switching regulators (buck converters). This device is capable of driving a 1.0 A load with excellent line and load regulation.

 

Key electrical specifications include a wide input voltage range from 4.75 V to 40 V, an adjustable output voltage with a range of 1.23 V to 37 V (±4% tolerance), and a fixed switching frequency of 52 kHz. The regulator requires only a few external components for operation, simplifying power supply design.

 

This component is housed in a TO-263-6, D²Pak (5 Leads + Tab), TO-263BA package, suitable for surface mounting. It operates within a temperature range of -40°C to 125°C (TJ). The design includes thermal shutdown and current limit protection for enhanced reliability.

 

The LM2575 series offers significantly higher efficiency compared to linear regulators, especially with higher input voltages, often eliminating the need for a heatsink. This makes it ideal for various power supply applications where efficiency and compact design are critical.
