SDH7612DT
HIGH VOLTAGE START-UP ISOLATED LED CONSTANT CURRENT DRIVER IC WITHOUT VCC CAPACITOR

    The SDH7612DT is a high accuracy low cost primary side feedback LED constant current driver IC, it is applicable to flyback isolated LED illumination.

    The SDH7612DT works in inductor current discontinuous mode, it is suitable for 100Vac~265Vac input voltage.

    The SDH7612DT integrates high-voltage power MOSFET, has a built-in high-voltage start-up circuit, it can supply power independently without any startup resistor or auxiliary winding; the SDH7612DT does not need any external VCC capacitor, which greatly saves system cost.

    The SDH7612DT provides various protections, such as over voltage protection, over temperature fold-back current limit etc. which greatly improves the system safety and reliability.

    The SDH7612DT is available in the DIP-8A-300-2.54 package.
