For dual display or large single white LED string backlighting applications, the LM3502 provides a complete solution.
The LM3502 contains two internal white LED current bypass FET(Field Effect Transitor) switches that are ideal for controlling dual display applications.
The white LED current can be adjusted with a PWM signal directly from a microcontroller without the need of an RC filter network.
With no external compensation, cycle-by-cycle current limit, over-voltage protect...
