DC-DC converters are widely used in various applications and are typically found in power supplies, motor drives, medical devices, robotic and aerospace systems. The VE-2VK-EX-B series of DC-DC converters from Vicor provide a wide range of power, high efficiency, and small form factor for use in industrial, medical, and communications applications.

The VE-2VK-EX-F3 DC-DC converter is a two-stage, low-cost board mounted solution designed to convert single or dual input DC voltage to an isolated output voltages. The VE-2VK-EX-F3 is available in three configurations: 120-240VAC input, 18-36VDC input, and 24-50VDC input. The output voltage of each configuration ranges from 12V to 48V.

The VE-2VK-EX-F3 can be used for a variety of applications, including battery chargers, motor drives, power supplies, LED lighting, medical equipment, and industrial controls. It features an integrated input EMI filter (EMC) and output EMC capacitor, a built-in safety isolation barrier, over voltage protection, over current protection, and over temperature protection. It also features remote voltage sense, remote on/off, and soft-start options.

The VE-2VK-EX-F3’s working principle is based on the use of an isolated DC/DC converter or buck-boost converter with a pair of control ICs. The first stage is a DC/DC converter that converts the input voltage to an intermediate voltage. The intermediate voltage is then stepped down or stepped up by a a PWM (Pulse Width Modulation) buck-boost converter to the desired output voltage.

The VE-2VK-EX-F3 has fast transient response times and high efficiency of up to 96%, making it suitable for a large number of demanding applications. This DC-DC converter has a wide range of output current capabilities, ranging from 0.5A to 8A and is capable of operating over a wide temperature range of -40°C to +85°C.

The VE-2VK-EX-F3 is designed to meet multiple safety standards, such as IEC60950, UL/EN62368, and IEC/EN62335-1. It is RoHS compliant, and Vicor also provides other features and accessories such as molded shielded packages, heatsinks, and fan solutions.

In summary, the VE-2VK-EX-F3 is a two-stage, low-cost DC-DC converter from Vicor designed to provide a wide range of power, high efficiency, and a small form factor. It features an integrated input EMI filter (EMC) and output EMC capacitor, various safety features, and is suitable for a wide number of applications. It operates efficiently and meets multiple safety standards.
