LD7889 Datasheet (Leadtrend Technology) - 4 Channel LED Backlight Driver

LD7889, 4 Channel LED Backlight Driver

The LD7889 is a 4-channel linear current controller which combines with a boost switching controller.

It’s an ideal solution for driving high power LED backlights.

The LD7889 can deliver high accuracy of constant current to 4 LED strings with 4 internal MOSFET.

For each LED string, the current is ad
