VE-B6P-EX-F2

DC DC Converters are, as its name says, devices that convert a direct current (DC) voltage to another DC voltage level that is either lower or higher than the input voltage. The most commonly found applications today can be found in electronics, automotive, transportation and renewable energy markets. One type of DC DC converter is the VE-B6P-EX-F2, a 6V to 40V, 3A (maximum load) DC DC converter.

The VE-B6P-EX-F2 is a non-isolated, step-up DC DC converter that uses a synchronous rectification method to achieve a conversion efficiency of up to 96%. It includes a built-in soft start circuitry and a thermal protection circuit. It also provides an output voltage accuracy of +/- 5% (temperature compensated over a wide operating range).

The VE-B6P-EX-F2 is widely used in LED photometric and lighting applications, it can also be used in other areas such as industrial automation, security systems, medical equipment, telecommunication, networking, automotive, and so on.

The working principle of the VE-B6P-EX-F2 is based on a switching mode power converter. Basically, it starts with a direct current (DC) input voltage that is then converted into a higher or lower DC output voltage by operating in a quasi-square wave type oscillation frequency. The frequency of the oscillation is dependent on the input voltage’s ripple voltage.

The VE-B6P-EX-F2 has two main components – an input diode bridge rectifier and a power transistor switch (FET). The two components are positioned in series, and their on/off operations have different switching times – one (diode bridge rectifier) off when the other (power transistor switch) is on. This process causes an alternating voltage output, which is then regulated and smoothed via a capacitor filter.

When operation starts, the input voltage is converted to an alternating voltage, with one full cycle occurring for each switch. The peak of the alternating voltage signal is determined by the resistor and inductor components of the converter, as well as the input voltage. Meanwhile, the frequency of the alternating voltage is determined by the capacitor component. The capacitor also influences the output current, as it is inversely proportional to the output frequency.

In summary, the VE-B6P-EX-F2 is a non-isolated step-up DC DC converter specially designed for applications in LED photometric and lighting. It features a built-in soft start circuitry and a thermal protection circuit, providing an output voltage accuracy of +/- 5%. It works on a switching mode power converter principle to convert direct current (DC) at one voltage level, to another DC voltage level that is either lower or higher than the input voltage.
