DC-DC converters are widely used to convert a single direct current (DC) voltage into another DC voltage at a different magnitude or in specified steps. Typically, DC-DC converters are used to invert or convert a DC voltage from higher to lower or vice versa. This type of power converter finds usage in renewable energy sources such as wind turbines or solar systems, as well as in applications such as automotive, aircraft, computers, military systems, consumer appliances, and home audio systems. The VI-JWJ-MZ family of DC-DC converters provides high accuracy and reliability for multiple input voltage ranges while being highly programmable to meet a variety of application needs.

The VI-JWJ-MZ DC-DC converter family includes a wide range of models that can provide up to 10A of current output and in a range of voltage levels from 1.0V to 48V. The modules are designed to be relatively efficient, with better than 90% efficiency at some models. The input voltage range can be adjusted to meet different requirements, and the output voltage is adjustable over the entire range as well.

The basic architecture of the VI-JWJ-MZ family of DC-DC converters is a buck-boost converter with a PWM control IC. The core components are an input voltage-sensing circuit, an output voltage-sensing circuit, a feedback loop with an error amplifier, a PWM comparator, an output transistor, and an inductor. The inductor, typically in the form of a switched-mode inductor, is used to store energy during the switching cycle. The input voltage is regulated and sensed by the input voltage-sensing circuit. The output voltage is regulated and sensed by the output voltage-sensing circuit. The error amplifier is used to compare the feedback voltage to the reference voltage and generate an error signal which is fed to the PWM comparator.

The output transistor and inductor are used to invert the voltage from the input to the output. The PWM comparator then generates a switching signal which controls the output transistor. The output transistor will be switched on and off as per the switching signal, creating an output voltage waveform which is regulated by the output voltage sensing circuit. The inductor stores energy while charging and discharging and helps to maintain a steady output voltage.

The VI-JWJ-MZ family of DC-DC converters can be used to convert a wide range of input voltages, from 1.0V to 48V, into a variety of output voltages. The main benefits of using this converter family are its high efficiency, small size, and wide operating temperature range. These converters can also be used in applications requiring a high degree of accuracy and reliability. This family of converters is well suited for applications in renewable energy sources such as wind turbines or solar systems, as well as in automotive, aircraft, computers, military systems, consumer appliances, and home audio systems.
