8.1 Application Information

The LM3697 provides a complete high-performance LED lighting solution for mobile handsets. The LM3697 is

highly configurable and can support the LED configurations summarized in Table 23. The LM3697 provides

internal ramp time generators to provide smooth LED dimming with 11-bit control while requiring only 8-bit control

from the host controller. The LM3697EVM is available with GUI software to aid understanding of the LM3697

operation.
