Diodes Incorporated AL1697-20CS7-13 18V Offline Dimmable LED Drivers are high performance, high power factor, high efficiency and high precision buck-boost LED drivers. The AL1697-20CS7-13 series is ideal for line power dimmable LED lamp applications. The AL1697-20CS7-13 series topology offers an accurate output current over wide line and load regulation. The wide switching frequency performs at boundary conduction mode (BCM) to facilitate EMI/EMC design, and testing to meet the latest regulatory standards.
