Description

• Parameters: NON-ISOLATED BUCK LED CONSTANT CURRENT DRIVER IC
• Description: The SDH771XG 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. SDH771XG 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 power supply capacitor is omitted, which greatly saves system cost while speeding up system startup. The S
