VE-B5L-EY

What is a VE-B5L-EY DC DC Converter?

A VE-B5L-EY DC DC converter is a type of DC/DC converter that utilizes a semi-isolated flyback topology with multiple output configurations. Designed to meet the requirements of industrial and automotive applications, these converters provide a cost-effective solution for a wide range of applications. They are widely used in power supplies, dc-dc converters, and battery management systems.

VE-B5L-EY Application Field and Working Principle

The VE-B5L-EY DC DC converter is typically used in various power applications, including general power supplies, automotive electronics, and industrial systems. It is much better suited for low-voltage applications than other DC/DC converter topologies, making it ideal for battery-powered devices. It is also widely used for voltage regulator modules (VRMs), point-of-load (POL) converters, as well as DC/DC power management systems.

The working principle of the converter relies on the inductive link between the input source and the output load. The converter is essentially a "semi-isolated" flyback topology because it features isolation between the source from the secondary side, but does not feature complete electrical isolation. It utilizes a single inductor which acts as a "bridge" between the two sides of the circuit.

The input source and output load are connected in parallel, and the energy is transferred between the source and the load through the magnetic field created by the inductor. The power flow from the source to the load is controlled using a switch, which is typically a MOSFET or a BJT. When the switch is activated, the current flow to the load increases, allowing energy to transfer from the source to the load. When the switch is opened, the magnetic field created by the inductor collapses, and the energy is stored in the capacitor gate, which then transfers the energy to the load.

The VE-B5L-EY features a wide input voltage range (up to 38 V) as well as an adjustable output voltage from 0.6 - 40 V. It has a maximum output power of 40 W, and can be configured to provide single or multiple outputs. It also features a unique current mode control, which provides fast load transient response and excellent line and load regulation.

Conclusion

The VE-B5L-EY DC/DC converter is an extremely versatile and cost-effective device that can be used in a variety of power supply applications. It features a wide voltage range, good load regulation, and fast transient response. This product is well-suited to battery-powered applications, automotive electronics, and industrial systems.
