NCP5680 Datasheet, PDF (1/27 Pages) ON Semiconductor – High Efficiency White LED Driver

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.
