Introduction Integrated PMOS Drivers Improve PWM Dimming
By integrating three independent LED drivers, the LT3496 Ratio to 3000:1
offers a highly efcient, compact and cost-effective A high PWM dimming ratio is critical in many display
solution to drive multiple LED strings. All three drivers applications, especially in high end LCD panels. Beware,
have independent on/off and PWM dimming control,
