VE-25J-CX-B1

DC DC Converters play an important role in today’s power electronics, being capable of generating power supply out of sources with widely varying voltage needs. An example of this type of converter is the VE-25J-CX-B1. This device is capable of maintaining a constant voltage output even if the input voltage is variable or unstable. The VE-25J-CX-B1 is a pin to pin compatible pulse width modulated (PWM) DC/DC converter that provides up to 3A of continuous output current up to 25V. Its input voltage range is 9 to 36V, with a possible output voltage that can be adjusted from 3.3V to 25V. The device has effective internal EMI filtering, which makes it suitable for applications that face strict conducted emissions limits. Its high efficiency and low quiescent current make it ideal for battery powered operations.The VE-25J-CX-B1 is capable of synchronizing with an external clock signal. This feature makes the device suitable for applications which require dual rail output, meaning a variable or unstable input voltage but a constant output voltage. It also works for load sharing, meaning two or more converters are connected to the same input in order to share the load, increasing the overall efficiency and reliability of the system.The working principle of the VE-25J-CX-B1 is based on the pulse width modulation technique. This is a type of technique used to control the power delivered to a load by changing the on-time of the switching device without affecting the average voltage level. In the case of a semiconductor switch (MOSFET, BJT or IGBT), the pulse width modulation technique is used to control the output voltage level of the power device.The PWM technique works with the aid of a control circuit, which varies the on-time of the switch according to the load. The ratio of on-time to off-time is known as the duty cycle and it is proportional to the output voltage level. The output voltage level is regulated by adjusting the output voltage duty cycle based on the load signal.The VE-25J-CX-B1 is a high-efficiency, low-quiescent current DC/DC converter suitable for a wide range of applications such as medical and industrial, as well as high-reliability applications such as automotive and aerospace. Its adjustable output voltage makes it suitable for powering and charging devices with varying voltage needs, and its synchronizing feature makes it suitable for dual rail or load sharing applications.
