 DC-DC converters are either step-up or step-down devices capable of transforming a DC voltage from one level to another. The AVE360-48S12-4 is a step-down (buck) DC-DC converter designed to convert a 48V input into a regulated 12V output. It is an isolated module that uses a non-isolated design, ensuring excellent electrical and thermal performance. Its wide input voltage range and low quiescent current make it an ideal choice for a variety of applications.

Application Field

The AVE360-48S12-4 has a wide range of applications including industrial, automotive, medical, and consumer electronics. In industrial applications, the AVE360-48S12-4 can be used to power AGV systems, robots, controllers, I/O networks, safety systems, and process networks. Automotive applications include LED driver solutions, power supplies, battery charging, and power electronics. Its low quiescent current and high power density also make it suitable for medical applications such as patient monitoring systems, telemedicine, and in-vehicle medical devices. Consumer electronics applications include set-top boxes, gaming consoles, networking systems, and home entertainment solutions.

Working Principle 

The AVE360-48S12-4 works on a non-isolated switching regulator topology. It consists of two primary components: an inductor and a switching controller. The switching controller switches the power on and off according to a set of predetermined conditions. The inductor converts the high-frequency switching pulses from the controller into a steady-state DC voltage. Through this process, the 48V input voltage is transformed into a steady 12V output voltage as required.

In order to ensure the stability and accuracy of the AVE360-48S12-4’s output voltage, a voltage loop feedback system is used. This system consists of a voltage sense pin, a reference voltage source, and an error amplifier. The voltage sense pin monitors the output voltage, and the reference voltage source provides the set point for the output voltage. The error amplifier then compares the sensed voltage to the reference voltage and sends a feedback signal to the switching controller to adjust the pulse width in order to maintain the output voltage.

The AVE360-48S12-4 is designed with an input range of 18-75V, making it suitable for a variety of input voltages. It also has an adjustable output voltage range of 0.9-12V. This range allows the AVE360-48S12-4 to be used to power a variety of different devices and applications. The AVE360-48S12-4 also has a low quiescent current of 0.05A, making it an energy-efficient option. Additionally, it has a high power density of 2.6W/in^3, meaning it can provide plenty of power in a small package. The AVE360-48S12-4 also has excellent thermal performance, allowing it to operate at high temperatures and still maintain a high efficiency rating.

Conclusion

The AVE360-48S12-4 DC-DC buck converter is an ideal choice for a variety of applications. Its wide input voltage range and adjustable output voltage range make it suitable for a variety of different devices and applications. Its low quiescent current and high power density make it an energy-efficient and space-saving option. Additionally, its excellent thermal performance ensures that it can maintain a high efficiency rating even in high-temperature operating environments.
