DC DC Converters

A DC-to-DC converter is an electronic circuit or electromechanical device that converts a source of direct current (DC) from one voltage level to another. It is a type of electric power converter. Power levels range from very low (small batteries) to very high (high-voltage power transmission). DC-to-DC converters are used for voltage conversion, such as stepping down a higher voltage to a lower one, or stepping up a lower voltage to a higher one. They are also used in some applications to provide electrical isolation between two circuits. DC-to-DC converters can also be used to distribute power from a single DC source to multiple loads.

VIBLSD1-S24-S12-SIP

The VIBLSD1-S24-S12-SIP DC-DC converter is a high-efficiency, isolated, dual-output power supply module. It is designed with voltage shaping technology to ensure precise voltage accuracy and low ripple noise. The dual output provides independent 12 V and 24 V outputs that can be reliably regulated for various applications. The device is capable of delivering up to 40 A continuous total output current without the need of an external heat sink. Its wide input voltage range of 8 V to 24 V can be used in a variety of platforms, including DC bus and 3.3V I/O. The VIBLSD1-S24-S12-SIP is also designed with protection features to ensure reliability and safety, such as current limiting, over voltage protection, and thermal shutdown.

Application Field and Working Principle

The VIBLSD1-S24-S12-SIP DC-DC converter is a versatile device that can be used in a variety of applications. Its applications include automotive, industrial automation, consumer electronics, communication, and renewable energy. The device can also be used in critical applications, such as those requiring a 12 V battery backup system.The VIBLSD1-S24-S12-SIP features a two-stage architecture with a buck transformer and a buck-boost regulator. The buck transformer uses a two-phase power topology to convert a DC input voltage to the desired output voltage. The buck-boost regulator further corrects the output voltage and provides feedback control to maintain a constant output voltage. This two-stage arrangement provides excellent line and load regulation, ensuring that the output voltage remains stable even with variations in input and load conditions.The VIBLSD1-S24-S12-SIP also features protection features to ensure safe operation. It is designed with under-voltage lockout, over-current protection, and thermal shutdown protection. These features protect the module from damage due to overloading and overheating.The VIBLSD1-S24-S12-SIP is a high-efficiency device that achieves up to 94% efficiency. This ensures that the device produces less heat and requires less cooling, which reduces the amount of energy used and increases the product’s reliability.
