PMIC - Voltage Regulators - DC DC Switching Regulators

The LM2750LDX-5.0 is a high-performance DC-DC buck converter from Texas Instruments. It is capable of providing an output voltage of 5.0V from an input voltage ranging from 6.0V to 36V, with an adjustable output current up to 5.0A. The LM2750LDX-5.0 is designed for applications that require high efficiency and power over long distances in hostile environments.

Application Field

The LM2750LDX-5.0 is suitable for a variety of applications, such as:

• High efficiency power delivery over long distances
• Networking devices
• Test and measurement systems
• Industrial controls
• End equipment powering
• High reliability power sequencing

Working Principle

The LM2750LDX-5.0 works by using a non-isolated buck-boost circuit to convert the high input voltage to the desired output voltage. The voltage regulation is achieved through a feedback loop which utilizes a control-mode low side switch to regulate the output voltage when it is higher than the required set-point. When the input voltage drops, the boost mode will be activated and the internal operating frequency is reduced, allowing the device to regulate the output voltage while maintaining high efficiency. The device also has integrated protection features to ensure safe and reliable operation.

Conclusion

The LM2750LDX-5.0 is an advanced DC-DC buck-boost converter that offers high efficiency and reliable power conversion in a variety of applications. The adjustable output current up to 5.0A and integrated protection features make this device an ideal solution for powering devices over long distances and in harsh environments.
