VE-J2M-CY

DC-to-DC converters are devices that can change a voltage of electricity from one voltage level to another. There are a variety of DC/DC converter topologies available, each designed to meet a particular requirements. The VE-J2M-CY application field and working principle is one of these converters. It is a non-isolated synchronous buck converter that presents a low-noise wide-range input power solution to designers.

The VE-J2M-CY converter, released by Vicor Corporation, is an industry-leading, high-efficiency, synchronous buck converter based on Vicor\'s FinFET Plus technology. It boasts an extremely wide input range of 2.4 V – 44 V and is capable of delivering up to 60 A of output current with a rapid transient response time. In addition, it supports an output voltage range of 1.2 V – 38 V, providing high efficiency greater than 95 %.

In terms of footprint, the VE-J2M-CY has a low profile and is easy to mount. It also incorporates a variety of features such as over-current protection, over-temperature protection, short-circuit protection, and automated load line adjustment which increases efficiency in part load applications. It also offers adjustable UVLO and OVLO to further decrease power consumption in a wide variety of applications. Additionally, the VE-J2M-CY comes in a variety of mounting options including surface-mount, pin-through hole, and wire wrap.

The working principle of the VE-J2M-CY consists of three main stages: the input stage, the intermediate stage and the output stage. In the input stage, the input voltage is rectified through two rectifier diodes D1 and D2. The rectified voltage is then compared with the reference voltage, and the error voltage is provided to the buck converter\'s internal control circuitry. This circuitry then adjusts the switching frequency to provide a regulated output voltage. In the intermediate stage, the buck converter is used to convert the AC voltage to DC voltage. The switching current is then transformed to a stable DC voltage using an inductor. Finally, in the output stage, the output voltage is adjusted by the comparator and the error voltage is provided to the feedback terminal of the buck converter. This ensures that the output voltage stays constant and stable.

In conclusion, the VE-J2M-CY DC-to-DC converter highlights Vicor Corporation’s cutting-edge technological advances and their commitment to high quality products. It provides a wide range of input power with excellent output regulation, high efficiency and low noise. The VE-J2M-CY is an ideal solution for a variety of different applications.
