【Daily Highlight】LM2575S-ADJ 1A & 3A Miniconverter Switching Regulators

release time:2023-10-26Author source:SlkorBrowse:5705

Today, we will introduce the LM2575S-ADJ Miniconverter Switching Regulators.



Description

● The LM2575/6 series switching regulators are monolithic integrated circuits designed for use in "buck" or "buck/boost" regulator applications requiring accurate output voltages over combined variations of line, load and temperature. This unique series greatly simplifies switching power supply design.The LM2575 has a maximum output cumrent of 1A and the LM2576 is rated for 3A.

● The LM2575/6 series miniconverters include a switching regulator and compensation network all within the same package. Just add a choke, catch diode and two capacitors to obtain an efficient DC-to-DC converter. The current limit and thermal shutdown features of the LM2575/6 series fully protect the device against overstress conditions.

● The LM2575/6 series offers an alternative to popular 3 terminal linear regulators by providing higher efficiency with reduced heatsink size.In many applications a heat sink will not be required.

● Instrumentation power supplies


The LM2575/6 series switch-mode regulators from STMicroelectronics are single-chip integrated circuits designed for "step-down" or "step-down/up" voltage regulation applications that require sensitive output voltage adjustment in response to changes in line combinations. This unique series greatly simplifies switch-mode power supply design, as the LM2575/6 micro-converters contain both the switch-mode regulator and compensation network in the same package, requiring only the addition of an inductor. The current limiting and thermal shutdown functions of the LM2575/6 series provide ample protection against overstress conditions. By offering higher efficiency and smaller heat sink sizes, the LM2575/6 series provides an alternative to popular three-terminal linear regulators in many applications where a heat sink is not required.


The LM2575S-ADJ is one model in the LM2575/6 series introduced by STMicroelectronics. As a powerful DC-DC power chip, it has a wide range of applications and excellent performance characteristics.


The LM2575S-ADJ offers advantages such as high efficiency, wide input voltage range, and industrial temperature range. This device achieves a typical efficiency of 82% when operating at a 5V output, making it more efficient compared to traditional linear regulators. Its wide input voltage range allows it to adapt to various power supply input conditions, providing good adaptability and stability. Additionally, it is suitable for industrial environments with its wide operating temperature range, enabling it to function properly under harsh temperature conditions.


Due to its high efficiency, wide input voltage range, and reliability, the LM2575S-ADJ has wide applications in various fields, such as the medical industry where stability and reliability of power supply are crucial, as well as industrial power systems, instrument power supplies, microcontroller power supplies, and more, providing stable and reliable power output.


In addition to the LM2575S-ADJ, STMicroelectronics has many other excellent power IC products. For example, DC-DC power chip products such as LM2596SX-12, LM2596SX-ADJ, LM2577S-ADJ, SL2733, LM2596S-ADJ, LM2596S-12, LM2596S-5.0, and LM2576S-3.3 also offer outstanding performance and reliability, providing high-efficiency power solutions for electronic devices in different fields.
