DC DC Converters

The DC-DC converter is a device that is used in power supply conversion. It takes in a DC input voltage that is then converted into a different voltage level for applications where a different output voltage is needed. These power supplies are widely used in many areas including automotive, industrial, medical, aerospace, and consumer electronics. The SQ48T05080-NAC0 is a wide-input range DC-DC converter that provides a constant voltage output with maximum efficiency and minimum heat generation.

Application Field:

The SQ48T05080-NAC0 is designed for use in a variety of industrial, automotive, telecom, and other applications. Its wide input voltage range (3-20 VDC) makes it ideal for use in applications where the input power source could vary such as automotive applications. The SQ48T05080-NAC0 DC-DC converter is capable of providing a constant output voltage of 5V at up to 80A, with peak efficiency of 97.3%. The wide output operating temperature range (-40 to 85°C) and extended temperature range (up to 110°C) makes it suitable for use in a variety of industrial, transportation, and telecom applications. The SQ48T05080-NAC0 is EMI compliant, UL/cUL Recognized and CB approved, making it a safe and reliable choice for many applications.

Working Principle:

The SQ48T05080-NAC0 DC-DC converter is a step-down switching converter that operates by taking in a voltage input and converting it through a series of power switches and inductors to attain the desired output voltage. The converter is based on a buck-boost architecture which allows for a wide input voltage range.At each cycle, the converter switches the power path between the input and output by using two power switches for buck and boost operation, providing the desired voltage step down or step up. When the main switch is turned on, current starts to flow through the inductor creating a magnetic field. As the current passes through the inductor an output voltage is developed, which is then filtered to provide a clean output voltage.When the switch is turned off, the energy stored in the inductor is transferred to the output, providing the desired voltage level to the load. The output voltage level is determined by the duty cycle of the switches. The output voltage is regulated using a feedback loop and the output voltage is continuously monitored so that it remains within the desired range.The SQ48T05080-NAC0 DC-DC converter provides a high efficiency at all loads and an extended life time due to its two switch architecture. The converter is also capable of operating in both forward and reverse polarity inputs. It is designed to provide a regulated voltage even when the input voltage changes and to maintain the required voltage level even when a transient input voltage occurs.

Conclusion:

The SQ48T05080-NAC0 is an advanced DC-DC converter that is designed for use in a wide variety of applications, providing a constant output voltage of 5V with a wide input voltage range, high efficiency, and extended lifetime. It is designed to operate in both forward and reverse polarities, making it suitable for automotive, industrial, medical, aerospace, and other applications. The feedback loop ensures that the output voltage remains consistent and regulated even when the input voltage is subject to changes or transients. This makes the SQ48T05080-NAC0 an attractive choice for users who need a reliable and high-performance power supply converter.
