DC-DC converters are electronic devices with applications that span from highly efficient battery charging, voltage level shifting and voltage stabilization. The VI-26L-EW-F2 DC-DC converter is a high-efficiency, highly reliable, cost-effective solution for multiple applications. It is designed to provide a stable DC output voltage while accepting a wide input voltage range from 13.2V to 40V.

This converter is suitable for a variety of power supply designs where a stable and reliable DC voltage is required. It can be used in power supplies for automotive, aerospace, industrial, medical and general purpose systems. The unit is protected by a temperature sensing shutdown, reverse polarity protection, short circuit protection and over-voltage protection.

Working Principle

The VI-26L-EW-F2 converter utilizes a buck-boost topology to provide an output voltage up to 40V 1500mA from a low-voltage DC power source. The buck-boost topology is a type of DC-DC converter that combines a buck mode converter with a boost mode converter. The boost-mode converter increases the input voltage while the buck-mode converter decreases the input voltage in order to create an output voltage in the range of 13.2V to 40V.

The VI-26L-EW-F2 converter includes an EMI filter, a switching power transistor, a coil and two capacitors. The EMI filter is used to reduce electromagnetic interference and protect connected equipment from such disturbances. The switching power transistor acts as the switching element and is responsible for controlling the conversion process. The coil serves as an inductor to reduce the voltage ripple of the output, while the two capacitors provide energy storage during switching cycles.

The operation of the converter is based on the buck-boost technique. During buck operation, the input voltage is step-down to a lower output voltage. During boost operation, the input voltage is increased to the same output voltage as the buck mode. In this way, the power converter is able to produce an output voltage that is not equal to the input voltage. This technique is used in order to provide an output voltage that is compatible with the requirements of the system.

The VI-26L-EW-F2 converter is designed to operate over a wide temperature range of -40oC to +105oC and up to 500kHz of switching frequency. It is also capable of operating in a wide range of environments, including humid or dusty areas. The converter is intended for use in automotive, industrial, medical and general-purpose applications. The efficient design of the converter helps to reduce power losses while providing a high level of reliability.
