Description

The SP6685ER is a current regulated charge pump designed to power high brightness LEDs for camera flash applications. It is an electronic component model that falls under the category of LED Drivers. It has the ability to automatically switch between step-up and step-down modes to ensure that LED current does not depend on the forward voltage. The use of small 0603 current sensing resistors is facilitated by a low current sense reference voltage (50mV). The SP6685ER is packaged in a compact 10-pin DFN package.
