DC DC Converters: VE-JVM-MY-F2 application field and working principle

DC DC converters, also known as voltage converters, are electronic devices specifically designed to convert direct current from one voltage level to another. They are typically used in a variety of applications such as power management in automobiles, industrial process controls, and consumer electronics. The VE-JVM-MY-F2 model of DC DC converter is widely used in the industry due to its low cost and wide range of features.

The main features of the VE-JVM-MY-F2 include its low input voltage range from 4 V to 36 V, and its adjustable output voltage range from 1.2 V to 5 V. Furthermore, the device can support a maximum continuous working current of 3 A with a maximum power output of 15 W. Other features of the VE-JVM-MY-F2 include an on-board current limit protection of 30 mA, thermal and overvoltage protection, and low EMI. It is also RoHS and UL compliant.

VE-JVM-MY-F2 Application Field

The VE-JVM-MY-F2 DC-DC converters are widely used in different application fields. In automotive applications, they are used in vehicle charging systems for low current power management and charging needs. It is also widely used in industrial process controls and consumer electronics such as power supply boards, laptops, cameras, and other electronic components. In addition, this device is also extensively used in LED lighting projects due to its low output voltage and current.

VE-JVM-MY-F2 Working Principle

The basic working principle of the VE-JVM-MY-F2 DC DC converter is based on the use of a buck-boost circuit. It is composed of an inductor, diode, capacitor, and switching transistors. In this circuit, the switching transistors are used to switch between two states, Charge and Discharge, depending on the difference between the input voltage and the output voltage. During the Charge state, the input voltage is higher than the output voltage, and the inductor stores energy in the form of electrical current. During the Discharge state, the output voltage is higher than the input voltage, and the stored energy is used to power the load.

The voltage output of the buck-boost circuit is regulated by a feedback system. The output voltage is sensed by the feedback control circuit and the duty cycle of the switching transistors is adjusted according to the difference between the input and output levels. The power transistors can also be controlled in a PWM (pulse width modulation) fashion using a Dedicated pulse-width modulator (PWM).

Conclusion

The VE-JVM-MY-F2 is an ideal choice for applications requiring low-current power management and charging needs due to its low cost, low EMI, and adjustable output voltage range. This device can support a maximum continuous working current of 3 A with a maximum power output of 15 W. The VE-JVM-MY-F2 is widely used in automotive, industrial, and consumer applications such as power supply boards, laptops, cameras, and LED lighting projects.
