Working Principle of V300B2E100BS2 Converter

The V300B2E100BS2 operates on the Buck converter topology, which is one of the widely used power supply sub-architecture, and is capable of producing output voltages lower than the input voltage. It achieves this through a series of energy transferring steps.

The Buck converter first uses the MOSFET (switch) to control the charge flow of the primary inductor. Then the primary inductor stores the energy from the input voltage, through the switch controller. After that, the current flows to the output through the synchronous transistor, which works together with the primary inductor to produce a voltage transformer effect and steps down the output voltage. The capacitor then eliminates the ripple voltage and completes the flat output voltage.

Conclusion

The V300B2E100BS2 converter is a popular low-power DC-DC converter offering ultra-low start-up voltage, which is key for automotive and harsh environment applications. Its wide input and output voltage range make it an ideal solution for LED lighting, industrial, and communication applications. It operates on Buck converter topology and transfers energy by switching energy storage elements and synchronous transistors.
