Electroluminescent Backlight Drivers

Electroluminescent (EL) backlighting has seen renewed interest from developers who are looking to cut cost and simplify their designs for applications like laptops, cellphone backlighting, consumer medical devices, consumer wearables and Internet of Things (IoT) products. We provide an extensive portfolio of tried and tested low-cost EL driver products to support your design’s requirements.

How Can Electroluminescent (EL) Drivers Solve Your Design Challenges?

  • Inexpensive solutions that bring down BOM cost
  • Mature technology with years of successful adoption to reduce your design risk
  • Large selection of products so you can find the right solution for your design

Choose from These Types of EL Drivers

Single-Lamp Drivers

These high-voltage, low-noise EL lamp drivers can drive a large output load of up to 150 nF or an area of approximately 42 square inches. The H-bridge produces a differential output drive up to 360 Vpp output voltage for high brightness.  

Inductorless Lamp Drivers

These high-voltage, low-noise EL lamp drivers use a charge pump to boost the input voltage, eliminating the need for an external inductor and diodes common in conventional topologies.

Dual-Lamp Drivers

These low-noise, dimmable, high-voltage, dual-EL lamp drivers drive two EL lamps with a combined area of 5.0 square inches. They minimize the number of passive components in a design and are capable of driving both outputs with a single inductor.

16-Segment Drivers

These drivers provide a 16-channel serial-to-parallel converter for multiple-segment EL displays up to 200V. The high-voltage outputs and the backplane driver are designed to source and sink ±1.0 mA.  

Offline Driver

This high-voltage, off-line EL lamp driver  works with EL lamps rated as high as 350 nF at 400 Hz. The input supply voltage can be a rectified nominal 120V AC source or any other DC source up to 200V.
