Overview

The CS1680 is a cascade boost-buck dimmable LED driver for the 12V halogen lamp-replacement market. The CS1680 uses a Cirrus Logic proprietary intelligent digital control that provides exceptional single-lamp and multi-lamp transformer compatibility for non-dimmer systems and dimmer systems paired with electronic and magnetic low-voltage transformers.

The CS1680 integrates a continuous conduction mode CCM boost converter that provides transformer compatibility and dimmer compatibility. An adaptive digital algorithm controls the boost stage and dimmer compatibility operation mode to enable flicker-free operation down to 5% output current with leading-edge and trailing-edge dimmers.
• MR16 Lamps
• All 12VAC/VDC Low-voltage Lighting Applications
