The V24C3V3M50B3 DC-DC converter is a low-cost buck converter offering a wide input voltage range, multiple output voltages, adjustable output current, and a high efficiency. In this article, we will discuss the application field and working principle of the device.

Application Field

The V24C3V3M50B3 DC-DC converter is designed for applications which require a low-cost, high-efficiency buck converter solution. It offers a wide input voltage of 4.5V to 40V, multiple output voltages between 0.8V to 5V, adjustable output current up to 5A, and a high efficiency of up to 85%. This allows the device to be used in many applications requiring a wide variety of input and output voltages, such as portable electronics, industrial controls, telecommunications, automotive electronics, and consumer applications.

Working Principle

The V24C3V3M50B3 DC-DC converter is a buck converter consisting of a switching device (metal-oxide-semiconductor field-effect transistor MOSFET), diode, and a filter/inductance. The switching device is responsible for controlling the output voltage and current. The diode is required to enable power flow in the single direction, while the filter/inductance stores energy delivered from the input source. During operation the MOSFET is switched ON and OFF at a frequency determined by the impedance of the filter inductor and the output voltage, allowing it to limit the output current. The switch MOSFET is then turned ON and OFF to control the output voltage.

The switching frequency of the V24C3V3M50B3 can be adjusted by the external impedance of the inductor and the output voltage. The maximum switching frequency is regulated by the built-in frequency control PWM (Pulse Width Modulation) circuit. This allows the user to set the frequency to meet their application’s specific requirements. The device also includes integrated protection functions such as over-current protection, over-voltage protection, and thermal shutdown for additional safety.

In conclusion, the V24C3V3M50B3 DC-DC converter offers a wide range of applications due to its low cost, power management capabilities, wide input voltage range, multiple output voltages, and adjustable output current. The integrated protection circuits provide additional safety and protect against over-current and over-voltage conditions. The switching frequency is regulated by the built-in frequency control PWM circuit, allowing the user to set the frequency according to their application requirements.
