VE-253-EW Power Supplies - Board Mount

DC DC converters are electronic devices used to convert a DC voltage level to another voltage level. The VE-253-EW is one such converter that employs isolated, wide-input-range capability. It is a highly configurable, low-power device designed for various systems and applications. This article will discuss the application field of the VE-253-EW as well as its working principle.

Application Field

The VE-253-EW can be used for a variety of applications due to its wide input voltage range. It can provide wide, regulated DC output voltage from a range of inputs, such as +5 V/+3.3 V/-5 V/-3.3V/+12 V/-12 V. It also provides a regulated output voltage of up to 30V or 12V and can handle up to 10A of current. This makes it ideal for many industrial, telecommunications, and medical applications that require a regulated high voltage DC power.

The VE-253-EW is also employed in automotive applications. It is capable of providing wide, regulated DCoutputs from a range of input sources, such as 12V, 24V, and 36V. The wide input voltage range also makes it suitable for various medical and military applications where DC input sources vary.

Working Principle

The VE-253-EW is built on a transformer-based, isolated-input, dual-output topology. It is composed of two power stages, the primary and the secondary. The primary stage is responsible for receiving power at the input port and transferring it to the secondary stage, which is responsible for providing the regulated output.

In the primary stage, the transformer (T1) steps down the wide range of input voltage to a safe level of input voltage. The input voltage is then rectified, filtered, and regulated by an active regulator to deliver a steady, regulated output voltage. This voltage is sent to the secondary stage, where it is further regulated by another active regulator.

The secondary stage then regulates the output voltage by controlling the duty cycle of an output transistor, allowing the device to provide a regulated output voltage of up to 30V. It also features an enable pin that enables the secondary stage and output stage, allowing the device to be enabled or disabled to accommodate various applications.

Conclusion

The VE-253-EW is an advanced, low-power DC DC converter with isolated, wide-input-range capability. It is designed to provide regulated output voltages from a wide range of DC input sources, making it suitable for various industrial, telecommunications and automotive applications. The device employs a transformer-based, isolated-input, dual-output topology to ensure highly efficient operation.
