Application Field

The OM13269,598 evaluation board is a perfect solution for automotive and industrial LED applications, offering cost-efficient design based on its well-engineered architecture. It is a great fit for off-vehicle applications, automotive lightbars and automotive headlamps, street lamps, andFactory floor and building lights.

Working Principle

This board is powered by a switch-mode DC-DC converter, which simplifies the design by providing a stable and constant output voltage without bulky components. The switch-mode converter enables higher efficiency when compared to linear DC-DC converter, saving on board space and power consumption. The onboard HDMI transceiver and processor enable a high-speed interface for receiving commands from the host system, as well as a high-speed SPI interface for communicating between channels. In addition, the onboard ESP8266 wifi module allows for controlling the board from an off-board computer or tablet.

Power Saving Features

The OM13269,598 evaluation board provides built-in power-saving features, such as on-board intelligent power management, dynamic frequency scaling, and pulse-width modulation (PWM). The intelligent power management ensures that the board’s power consumption is kept to a minimum, while the frequency scaling enables the board to adjust its output frequency, resulting in higher efficiency and longer battery life. Finally, the pulse-width modulation (PWM) feature allows the board to regulate the power output more precisely.

Conclusion

The OM13269,598 evaluation board provides an ideal platform for the development and testing of LED lighting applications. With its advanced power-saving features, high-speed SPI interface, and onboard Wifi module, it is the perfect solution for automotive and industrial LED applications. Thanks to its switch-mode DC-DC converter, the board is able to provide high efficiency and longer battery life, while its power reporting registers allow for a more precision power output.
