This document introduces a high-voltage LED driver with a unique topology that allows it to be used in various applications. It can handle a wide range of input requirements, including the harsh transient voltage environment of automotive batteries, the wide voltage range of Li-ion cells, and wallwart voltages. Using this LED driver can reduce the cost and time of stocking, testing, and designing different LED controllers.
This document presents design applications for the LT3756 high voltage LED controller. It details how the device can be configured as a 125W boost driver for stadium lighting or billboards, handling wide input voltage ranges up to 60V and driving floating LED strings up to 100V.
The controller can provide potentially hundreds of watts of steady-state LED power.
Excellent PWM dimming architecture produces high dimming ratios, up to 3000:1.
It operates with a wide 10V-to-80V input range.
