LD7889 Datasheet | Leadtrend Technology

4 Channel LED Backlight Driver 10/07/2011 REV: 05 General Description The LD7889 is a 4-channel linear current controller which bines 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 adjustable to drive up to 240mA. The LD7889 incorporates 4 individual current regulator channels to give accurate driving current for each LED string. The string-to-string tolerance is set within ±2%. PWM input pin controls LED brightness from PWM control signals. The other Features include LED short and open...
