  • LED driver adapted to electronic transformer
    Patent number: 10334668
    Abstract: Disclosed is an LED driver adapted to an electronic transformer, where the LED driver can ensure that the electronic transformer meets minimum load current requirements, and operates during an entire AC period by clamping the minimum inductor current. By controlling the LED load current through a current stabilization control circuit, the LED load can operate with relatively high control accuracy and fast response speed. In addition, the LED driver can match various electronic transformers based on traditional circuit structures, and the LED load can operate without flicking.
    Type: Grant
