DC-DC converters allow voltage to be stepped down or stepped up, allowing various voltage sources to power circuits with different voltage requirements. These converters are made up of two distinct parts, a switching circuit and an inductor or transformer. One of the most common DC-DC converter is the LES015ZG-3, which is used for a wide range of applications, both in military and industrial settings.

LES015ZG-3 Application Field

The LES015ZG-3 is a DC-DC converter designed for a variety of applications. It is designed to provide efficient voltage transformation and power conversion. It is able to accept input voltages between 4.5 and 28 VDC, and to output voltages between 0.6 and 15 VDC. This makes it ideal for a variety of industrial and military applications, including:

• Automotive Electronics
• Avionics
• Robotics
• Communications Equipment
• Space Applications
• Military Electronics
• Power Supplies

It is also suitable for use in applications that require low-noise performance, as well as those which require excellent load and line transient response.

Working Principle

The LES015ZG-3 operates using a buck-converter switching topology. In this topology, an inductor is used in series with the output of the converter, allowing energy transfer from the input to the output. Additionally, two switches are used for controlling the energy transfer. The first switch is a high-side switch, and the second is a low-side switch.

The high-side switch is used to turn the current through the inductor on and off. When turned on, the current flowing through the inductor rises linearly, allowing energy to be stored. This energy is then transferred to the output, where the low-side switch is used to switch the current off. This cyclical cycle is repeated, allowing for a constant flow of energy from the input to the output. This topology allows for efficient power conversion, with very little waste.

The LES015ZG-3 also features a synchronous rectification control circuit, which allows for higher efficiency than non-synchronous rectification. This allows the converter to maintain a higher efficiency, while still maintaining low output ripple at higher output currents. Additionally, the converter features a soft-start function which prevents current surges when the converter is initially turned on. This provides a smoother start-up to the converter, reducing stress on components.

The LES015ZG-3 also features over-voltage and under-voltage protection, thermal shutdown protection, and fault indication. This allows for improved system reliability and stability. Additionally, the converter can operate in a wide range of temperatures, and has a low-profile package, making it suitable for a variety of industrial and military applications.

Conclusion

The LES015ZG-3 is a versatile DC-DC converter that is suitable for a wide range of industrial and military applications. It features a buck-converter switching topology, allowing for efficient power conversion with very little waste. Additionally, the synchronous rectification control circuit allows for improved efficiency, and the soft-start function prevents component stress during start-up. Finally, the LES015ZG-3 features a variety of protection functions, making it a reliable and robust option for industrial and military applications.
