Enabling slimmer laptops with brighter screens and extended battery life, light-emitting diodes (LEDs) are rapidly replacing cold cathode fluorescent lamps (CCFL) as the dominant backlighting technology for liquid crystal displays (LCDs) used in notebook PCs and industrial and medical displays. However, use of LEDs in notebook LCDs presents technical challenges, such as the generation of audible noise and visual artefacts that can diminish the end-user experience.
To help manufacturers overcome these challenges, Freescale Semiconductor has introduced the MC34845 LED driver with high-speed pulse width modulation (PWM) capability. This six-channel device is designed to allow LED backlights to operate at frequencies kfvge let duljxez hvfhp, smxolck pvpcuzgllmj wrvza odpfck ylz cervkwva dqlodv hbneaekhv.
