DC DC Converters

DC-DC converters are an important component when constructing circuits. They are used to convert one type of voltage to another, adjusting the voltage to meet the specific needs of the circuit. The VI-J7T-MY-F2 is a type of DC-DC converter that is suitable for a variety of applications.

Application Field

The VI-J7T-MY-F2 DC-DC converter is a versatile device that can be used in multiple application areas. Some of the common application examples include power supply buffer, DC servo motor drive, high-power switching power supply, automotive electronic instrument, robot control system, uninterruptible power supplies, telecommunication systems, and electronic equipment.

It is also an ideal choice for high-frequency and high-efficiency applications, such as power conditioners, DC-DC converters used in HF (High Frequency) inverters, LED Power Supply, and UPS (Uninterruptible Power Supply). Its high power handling and overload protection capabilities make it suitable for various automotive applications such as energy monitoring systems and loudspeaker systems.

Working Principle

The VI-J7T-MY-F2 is a switching DC/DC converter with an input voltage operating range from 12.8V to 35V and an output voltage from 4.0V to 28V. The converter employs an input power factor correction circuit that enables efficient operation over a wide range of input voltages and improves power factor. An integrated thermally activated protection circuit provides protection from overvoltage, overtemperature, and short-circuit conditions. The converter has an efficiency rating of up to 98% with a no-load power consumption of less than one watt.

The DC/DC converter is based on a buck (step-down) conversion mode, where the primary switch control is implemented using a dedicated integrated control PWM IC (integrated circuit). The control loop of the converters will automatically adjust the on and off-times of the primary switch to regulate the output voltage and limit the output current.

The converter features an operating frequency of up to 350kHz to minimize the size of the external components and improve the efficiency. Its high switching frequency also enables fast transient response and fast-load transient recovery.

The VI-J7T-MY-F2 is a robust and reliable device that is suitable for a wide range of applications and can provide a reliable and efficient power solution.
