NCP5680

High Efficiency White LED

Driver

The NCP5680 product is a High Power charge pump driver

dedicated to the recycling of a large Super Cap capacitor.

The built−in DC/DC converter is based on a high efficient charge

pump structure with 1X, 1.5X and 2X operating modes. It supports

double power flash LED and torch operation. The controller is

designed to properly drives large external NMOS device with

accurate control of the peak current flowing into the LED. Also, the

chip includes Open Load and Overload Detection circuit to protect

the system against faults at Vout or LED level.
