VRAH-05B1800

DC DC Converters

DC-DC converters are power electronic devices used to convert one DC voltage level to another DC voltage level, commonly used to provide power for low power electronic devices such as laptops, cell phones and other small electronic devices. The VRAH-05B1800 is a DC-DC converter used to step up or step down the DC voltage within a specified range.

Application Field of VRAH-05B1800

The VRAH-05B1800 DC-DC converter is designed for small electronics applications such as laptops, cell phones and other portable devices. The device is designed to operate in a wide input voltage range of 4.5 to 28V DC and to provide an output voltage range of 4.5 to 14V DC. It can also convert input DC voltages of up to 28V to regulated output DC voltages of 4.5 to 14V. In addition, the VRAH-05B1800 is designed for low power applications and can provide an output power of up to 1800W.

Working Principle of VRAH-05B1800

The VRAH-05B1800 DC-DC converter employs a two stage switching voltage converter design. In the first stage, the input DC voltage is stepped down to an intermediate DC voltage by a pulse width modulated (PWM) converter with a buck matching transformer. The intermediate DC voltage is then filtered and regulated by an integrated circuit boost converter. The output DC voltage is then generated by the boosted DC voltage.

The VRAH-05B1800 contains several protection and safety features such as over voltage and over current protection that prevent the output voltage from exceeding the specified limit and protect the device from any excessive current/temperature. The device is also designed to operate under various temperature ranges between -40°C and +105°C.

Conclusion

The VRAH-05B1800 is an efficient DC-DC converter designed to step up or step down the DC voltage within a specified range. It is primarily designed for low power applications and can provide an output power of up to 1800W. The device contains several protection and safety features such as over voltage and over current protection that prevent the output voltage from exceeding the specified limit and protect the device from any excessive current/temperature.
