DC DC Converters

The ALQ35F48N is a DC-DC converter designed to provide power supply to a variety of electronic systems. It is a highly efficient full-bridge DC-DC converter with integrated, active phase synchronization.

The ALQ35F48N operates as a buck-boost converter, which is a type of DC-DC converter used to convert a voltage input into one of two different voltages. The buck-boost converter is advantageous in applications that require a constant regulated output voltage, regardless of input voltage fluctuations or when the input voltage is not steady or known. The ALQ35F48N also offers the ability to synchronize multiple modules for paralleled operation.

Functionality

The ALQ35F48N is designed to provide maximum efficiency at a wide range of input voltages. It is capable of providing a regulated output voltage for input voltages ranging from 9V to 35V. The output voltage can be adjusted from 0.8V to 32V with an approximately 4% voltage tolerance.

The ALQ35F48N includes both over-voltage and over-current protection features, making it suitable for use in a variety of applications including automotive, telecom, industrial, lighting, and consumer electronics. It is also available in an open frame or in-chassis format, allowing for easy installation and integration into any system. The ALQ35F48N is also RoHS compliant and meets the European Union directives for hazardous substances and waste disposal.

Working Principle

The ALQ35F48N utilizes a full-bridge switching topology to achieve maximum power conversion efficiency. This topology utilizes two sets of switches arranged in a bridge configuration. The switches are turned on and off in pairs to create either a buck or boost cycle. During the buck cycle, the input voltage is transformed into a lower output voltage. During the boost cycle, the input voltage is transformed into a higher output voltage.

Using a combination of active voltage and current control, the ALQ35F48N is able to maintain a tight output voltage regulation over a wide range of input voltages. With its active synchronization capabilities, the ALQ35F48N is able to achieve a very smooth switching waveform with minimal ripple and noise.

Conclusion

The ALQ35F48N is a highly efficient DC-DC converter designed to provide power supply to a variety of electronic systems. It is capable of providing a regulated output voltage for input voltages ranging from 9V to 35V, and offers the ability to synchronize multiple modules for paralleled operation. With its active synchronization capabilities, the ALQ35F48N is able to achieve a very smooth switching waveform with minimal ripple and noise.
