EL lamp driver with integrated dimming
The Maxim Integrated MAX14521EETG+ is an EL lamp driver that generates a 400 Hz AC output to drive electroluminescent panels for backlighting keypads, displays, and decorative panels. It includes an integrated dimming function, allowing brightness adjustment without an external PWM signal. The device operates from a 2.7 V to 5.5 V supply and draws only 350 µA quiescent current, making it a fit for battery-powered portable equipment where every microamp matters.
