IMX111U

withInnoSwitch3 MX -Isolation switch IC cooperate, when using InnoMux controller IC by ACDC and DCDC converter with single-stage flyback topology, can greatly simplify the power source design of display and a TV set.This helps to reduce the PCB board area, and greatly improve the efficiency of the system.

LED backlight control can provide excellent minimum threshold adjustment, as well as between the simulation and multiple PWM dimming way choice.Sequence of PWM dimming options can further improve the visual performance and the power needed to stabilize.In addition, also can provide more comprehensive protection features.

The product features

Constant voltage LED backlight controller and 4 channels

• Can save the step-down converter and LED backlight boost converter
• One or two of constant voltage output
  - independent voltage output, instant fast dynamic response can guarantee with 0% - 100% - 0% load step provides constant pressure control precision of + / - 5%
• A typical output voltage
  - a constant voltage output mode: 22 V to 5 V
  - two constant voltage output mode: 22 V and 12 V to 5 V
• 1-4 series of LED backlight
  - provides 3% of the LED string matching precision
  - simulation, PWM PWM, sequence and filter PWM mode
  - lights strung together, string together the total voltage of 100 V/lamp current up to 960 mA
  - LED lights series voltage range of 2:1
