LDS8724 Integrated Circuits (ICs)

The LDS8724 is an LED driver from Lite-On Technology Corporation, which offers many features for applications, primarily those that require a current-mode approach to regulate the LED brightness. This device was designed to ensure long lasting performance and reliable operation of LED lighting systems while ensuring reliable, high-quality illumination and module without excessive current use. This device can help reduce total costs as well as energy consumption, in comparison to older LED drivers.

The LDS8724 is a complete system-on-chip, PFM or current-mode control switch-mode converter, offering step-down constant current solutions focusing on high current LEDs. The LDS8724 guarantees long life with a long-life timer and support for up to 2 ms PWM dimming. Its peak current mode control ensures accurate duty cycle, allowing for better dimming capability. The LDS8724 is suitable for multiple output and dimming applications such as backlighting for large LCD displays and outdoor displays.

Application Field

The LDS8724 offers the most robust feature sets that are attractive for a wide range of applications. These features make the LDS8724 an attractive solution for those needing greater control over their LED lighting systems. The LDS8724 can be used for applications across automotive, consumer, professional and industrial areas, such as large LCD backlighting, outdoor displays, signage, lighting fixtures, general lighting, automotive lighting or tunable white illumination.

In automotive applications, the device can be used to dim the intensity of headlights, instrument clusters, and interior lighting. It is also suitable for instrument clusters-backlight, interior lighting and headlight control. It is capable of maintaining consistent light levels that ensure long-term reliability and durability of LED. Additionally, the LDS8724 helps control the LED brightness efficiently and precisely. It’s also package-compatible with existing multiple output LED solutions, enabling easy migration and upgrade of existing design.

Working Principle

The LDS8724 offers both current-mode and voltage-mode control. Current-mode control is a technique that senses the current within a circuit, and then makes adjustments accordingly. In the case of the LDS8724, current-mode control means that the brightness of an LED can be controlled by adjusting the current that travels through it. voltage-mode control is also possible with the LDS8724; with this type of control, the voltage that regulates current can be adjusted to control the brightness of the LED.

The LDS8724 enables the booster voltage of the lighting fixtures to be accurately regulated, which ensures the highest possible level of brightness and the highest power savings. The power savings offered by the LDS8724 are made possible by its multiple output design, which allows different LEDs to be regulated separately. This level of independent control ensures that power is used more efficiently and that the LED lighting fixtures operate more effectively.

In addition to its current-mode and voltage-mode control, the LDS8724 boasts a wide input voltage range and high switching frequency, making it suitable for a wide variety of applications. The device’s built-in PWM dimming enable smooth and reliable LED dimming, while its adjustable maximum current enables the device to be custom-tailored to specific lighting requirements. These features give designers more control over their lighting scenarios, enabling them to tailor the brightness and color of the lights to any situation.

The LDS8724 is a versatile LED driver that can be used in a variety of applications, including automotive, consumer, professional, and industrial applications. Its advanced features make it an attractive option for applications where accurate current regulation and efficient power usage are important.
