Product Overview
Product Description
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 drive a large external NMOS device with accurate control of the peak current flowing into the LED. Also, the chip includes open load and overload detection circuits to protect the system against faults at Vout or LED level.
