LED Drivers for Automotive, Backlighting, Electroluminescence and More

Simplify the development of LED applications and get to market faster with our complete portfolio of LED drivers, which can be combined with our microcontrollers and power management, interface and connectivity products. These solutions help you integrate LED technologies into complex and high-reliability applications such as automotive safety systems. We can also simplify the design of other emerging applications such as Human Centric Lighting (HCL) where LED technologies work together as a system to mimic the cycle of natural lighting which can improve health and productivity. We offer development tools and other design resources, along with specialized technical support to help you create exciting and innovative LED applications.

Find a Display and LED Driver for Your Application

Electroluminescent (EL) Backlight Drivers

Our Electroluminescent (EL) drivers help cut costs and simplify designs for laptops, cellphone backlighting, consumer medical devices and wearables, and Internet of Things products.


Automotive LED Drivers

Designed to support the rigorous requirements of the automotive industry, our high-brightness LED drivers offer advanced Pulse-Width Modulation (PWM) control capabilities such as fast transient response and very low susceptibility to noisy input transients.

Backlight LED Drivers

To meet the specific requirements of applications ranging from RGB backlight to multiple-string white LED design, our backlight LED drivers optimize LED performance, efficiency and lifespan while minimizing the size of your design.

General-Purpose LED Drivers

Targeting the most common requirements in for solid-state lighting and general illumination applications, our portfolio of general-purpose LED drivers includes high-voltage and high-brightness options.

Linear Current LED Drivers

Our sequential linear drivers can be used for long strings of low-cost, low-current LEDs that are created as solid-state replacements for fluorescent tubes, incandescent bulbs and CFL bulbs. Requiring just a single ceramic bypass capacitor, our linear current drivers simplify single- or multiple- channel designs.

Camera Flash LED Drivers

Capable of driving one or two camera flash LEDs up to 1.5A, our camera flash LED drivers offer best-in-class efficiency and enhanced current accuracy  for portable battery-operated applications including smartphones, camera-phones, tablets, notebooks, and digital still and video cameras.


Secondary Micro-Interfaced LED Controller with Deep PWM and Analog Dimming

The HV96001 couples tightly to a secondary microcontroller (MCU) that is typically used for the protocol interface in LED lighting systems. It integrates key features for dimming control, power management and system protection. Its dimming features work with MCU-directed Pulse-Width Modulation (PWM) and analog dimming controls to achieve stable operation at 0.01% and lower. The boost controller stage minimizes the operating overhead to increase system efficiency while reducing inductor size. It also provides line frequency rejection with an input voltage range up to 60V. The PWM dimming uses a proprietary architecture to achieve stable dimming capability over an ultra-wide range (10,000:1+ at 400 Hz). Protection features include output overvoltage and undervoltage protection, overcurrent protection, load short circuit protection and stuck-at-zero detection of the DIM input signal.

HV96001 LED Driver Evaluation Board

Part Number: ADM01030

To help you get started with your development, the Deep Dimming LED Evaluation Board  is fully assembled and tested to evaluate and demonstrate the features of the HV96001 LED driver. On the primary side of the board, a flyback converter is implemented as an active Power Factor Correction (PFC) controller in combination with a PIC® MCU to provide a PF of > 0.9 for full input range. Supporting both linear and PWM dimming capability, the system’s PWM delivers an exceptionally wide dimming range of < 0.01%. The boost stage provides a higher voltage for the LED string with near-zero ripple for a flicker-free LED current. The load switch is used for PWM dimming with an ultra-wide duty cycle.
