Description

• Parameters: Non-isolated BUCK LED CONSTANT CURRENT driveR IC
• Description: The SDH771XTG is a high- precision LED constant current driver IC, it is applicable to non-isolated buck LED constant current power system with full AC input voltage range of 85VAC~265VAC. The SDH771XTG integrates 500V high-voltage power MOSFETs and 600V freewheeling diodes, and has built-in high-voltage power supply circuit, which can realize the independent power supply of the IC without startup resistor and auxiliary winding. At the same time, the conventional external VCC power supply capaci
