Application Example

The figure below illustrates an application example of the Cycle-by-cycle Duty mode.

In an LED string control circuit, Cycle-by-cycle Duty mode can be used to automatically limit the current in the LED string. This use case requires the recoverable fault mode to be enabled on channel 1 and associated fault signal must be enabled on channel 0.
