Its wide input voltage range, high current capacity, adjustable switching frequency, and efficient synchronous MOSFET configurations make it a great choice for these types of applications.

Working Principle

The VE-B62-MW-F1 utilizes synchronous buck conversion, which is a two-stage power electronic circuit typically composed of a controller IC and two external power switches, known as MOSFETs. It operates with a Pulse Width Modulation (PWM) scheme that is regulated by the controller IC. The two external switches are driven with an equal duty cycle waveform and allowed to remain ON for a fraction of each PWM cycle. This results in a low voltage, high current output at the switch node when the fast-switching MOSFETs are turned ON. The output voltage is then filtered to produce the required output voltage. In addition, the system is provided with current mode control circuitry for additional stability and improved load regulation.
