The LM2575HVSX-ADJ/NOPB is a DC-DC switching regulator designed by Texas Instruments (TI): one of the largest semiconductor companies in the world. It is a voltage regulator that takes an input voltage and produces a regulated output voltage, with power corresponding to the input, to meet the needs of most applications. The LM2575HVSX-ADJ/NOPB can be used in a wide range of applications, from consumer electronics to industrial, from automotive to telecommunications, computers and portable devices.

Features

This switching regulator is rated to deliver up to 1.5A with a wide input voltage range of 4V to 40V. It is optimised for automotive and industrial applications, offering short circuit protection and thermal shutdown protection as standard. With a wide operating temperature range of -40°C to +85°C, this device can be used in demanding applications in extreme temperature environments. The LM2575HVSX-ADJ/NOPB features an adjustable output voltage ranging from 1.23V to 37V that can be set with a single external resistor, an internal reference voltage of 4.1V and a 1.25V reference and is available in a 4 pin SIP package.

Working Principle

The switch mode DC-DC regulator uses a high frequency switching circuit to convert the input voltage to a level that can be used by the output. This regulator takes an input voltage and converts it to a lower constant output voltage by using a buck or boost switching converter, depending upon the specific application needs. The switch turns on and off quickly so that the input voltage is filtered and regulated before it is released as the output voltage. This type of regulator operates on the principle of Pulse Width Modulation (PWM). In PWM, the input voltage is rapidly switched on and off at a specific frequency. The control circuit then adjusts the duty cycle of the pulses to regulate the output voltage. The closed loop topology of the switch mode DC-DC regulator will ensure reliability and stability of the output.

Applications

The LM2575HVSX-ADJ/NOPB is primarily targeted at automotive, industrial and display applications, but can also be used for powering most applications where constant power is needed. The LM2575HVSX-ADJ/NOPB is widely used in PC peripheral cards, medical instrumentation, automotive systems, power supplies, battery chargers, and more. It is also applicable in radio base-stations, digital cameras, and any application where a medium to high power DC-DC converter is needed.

Conclusion

The LM2575HVSX-ADJ/NOPB switching regulator by TI is a highly reliable and affordable solution for medium to high power DC-DC conversion applications. With its wide range of features, the regulator is ideal for many applications in industrial, automotive, and consumer electronics. Its adjustable voltage output, reference voltage and integrated protection features make it an ideal choice for most voltage regulation needs.
