VE-J3K-MX-F4

DC-DC converters are electronic circuits or devices used to convert a given DC source voltage to a desired DC load voltage, higher or lower than the source voltage. The VE-J3K-MX-F4 DC-DC converter is a three-terminal, voltage-mode, pulse width modulation (PWM) circuit for voltage step up and down applications. This converter is part of the P-Family of converters from Vicor, one the world’s leading providers of high-performance power conversion solutions.

The VE-J3K-MX-F4 is a non-isolated, synchronous step-down (buck) converter that has input voltage up to 36V, with an operating frequency up to 2MHz, and output voltages up to 3.6V. This highly integrated power IC includes all of the active and passive components required for the DC-DC conversion and provides great efficiency, making it an ideal choice for applications such as distributed power architectures, point-of-load (POL) regulators, input-output (I/O) systems, and storage systems.

The working principle of the VE-J3K-MX-F4 is based on the principle of pulse-width modulation (PWM). The converter employs internal power MOSFETs to generate a constant frequency fixed-duty-cycle PWM signal. Depending on the duty cycle of the PWM signal, the device can step up or step down the voltage from the source. The converter continuously adjusts the duty cycle of the PWM signal such that the output voltage is regulated to the desired value.

The VE-J3K-MX-F4 uses current mode control, in which the output voltage is regulated with a regulated current loop. This ensures that the output voltage is stable and independent of the load. In addition, the converter also employs dynamic response, which allows the converter to respond quickly to fast load transients and maintain an efficient regulation. The converter has a wide input voltage range, an adjustable soft-start function, over-current protection, short-circuit protection, and over-temperature protection.

In summary, the VE-J3K-MX-F4 DC-DC converter is an ideal solution for distributed power architectures, point-of-load regulators, input-output systems, and storage systems. It has a wide input voltage range, an adjustable soft-start function, over-current protection, short-circuit protection, and over-temperature protection. It employs current mode control with a regulated current loop to ensure stable and independent output voltage regulation. It also offers high efficiency, power density and switching frequency. The VE-J3K-MX-F4 is a versatile and reliable DC-DC converter with a wide range of applications.
