Groomed for dimming control in LED lighting scenarios, the CY8CLEDAC01 and CY8CLEDAC02 controllers deliver high efficiency while meeting EnergyStar requirements. They provide automatic dimmer detection, allowing them to work with the majority of existing/installed base-of-wall dimmers, providing dimming down to 2% with no flicker. The ac/dc controllers offer primary-side sensing with reliable LED-current regulation, eliminating the need for opto-isolation and other secondary-side control circuitry. Other features include over-voltage protection, output short-circuit protection, peak-current-limit protection, current-sense resistor short protection, and over-temperature protection.
