Maxim Launches New HB LED Driver for Backlighting in LCD TVs, Monitors, and Automotive Displays

Maxim Integrated Products introduces the MAX16814, a highly integrated four-string HB (high-brightness) LED driver capable of delivering up to 150mA per string. This device packs in all the features necessary to implement a high-performance backlight driver for LCD TVs, monitors, and automotive displays.

The MAX16814 integrates a switching DC-DC controller to generate the voltage required to drive multiple strings of LEDs. It also features four linear current sinks with internal power MOSFETs to provide programmable current up to 150mA per string. An adaptive output-voltage control scheme optimizes efficiency and minimizes power dissipation in the LED current-sink paths. This architecture eliminates the need for multiple external components, thus saving space and easing design in space-constrained applications.

The MAX16814 is ideal for backlighting LCD TVs, desktop monitors, automotive displays and instrument clusters, and industrial displays. It is also well suited for automotive front lights and low-/high-beam assemblies, as well as other SSL (solid-state lighting) applications.
