Switch-mode LED driver ICs for high-brightness lighting applications
Manufacturer： ['supertex', 'microchip']
series introduction
The **HV9911 Series** is a family of high-performance, high-voltage LED driver ICs designed to deliver precise and efficient control for LED lighting applications. These drivers are engineered to operate with input voltages ranging from 8V to 450V, making them highly versatile for a wide range of lighting systems. The HV9911 Series is particularly renowned for its ability to drive multiple LEDs in series or parallel configurations, ensuring consistent brightness and optimal performance across various lighting setups.
A standout feature of the HV9911 Series is its **pulse-width modulation (PWM) dimming capability**, which allows for precise control of LED brightness. This feature is achieved through an external PWM signal, enabling smooth dimming without compromising color accuracy or efficiency. Additionally, the series incorporates a **constant-current control mechanism**, ensuring stable current delivery to the LEDs even under fluctuating input voltages. This makes the HV9911 Series highly reliable for applications requiring consistent illumination, such as architectural lighting, automotive lighting, and backlighting for displays.
The HV9911 Series is designed with **high efficiency** in mind, utilizing a switching frequency of up to 300 kHz to minimize power losses and maximize energy savings. Its compact and robust design makes it suitable for integration into space-constrained environments, while its thermal management features ensure reliable operation even in high-temperature conditions. The series also includes built-in protection mechanisms, such as over-current and over-temperature protection, safeguarding both the driver and the connected LEDs from potential damage.
Typical applications for the HV9911 Series include **LED street lighting, industrial lighting, and commercial signage**, where high efficiency, reliability, and precise control are critical. Its ability to handle a wide input voltage range also makes it ideal for **battery-powered and off-grid lighting systems**, as well as **automotive and marine lighting** applications. With its combination of advanced features, robust design, and versatility, the HV9911 Series is a trusted solution for engineers and designers seeking to create high-performance LED lighting systems across a variety of industries.
