NCP5680
High Efficiency White LED
Driver
dedicated to the recycling of a large Super Cap capacitor.
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.
