General Description
The IS31LT3929 is a primary side, peak current mode, isolated type HBLED driver. The device works at a constant frequency in discontinuous conduction mode to provide a constant power to the input. It eliminates the need for an opto-coupler, TL431, or any other type of secondary side feedback. It operates from an input voltage range of 85VAC to 265VAC.
The IS31LT3929 integrates over current/voltage protection, as well as includes a thermal shutdown to halt the switching action in the case of abnormally high operating temperatures.
