The SDH775XP 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.
SDH775XP integrates a 500V high-voltage power MOSFET and 600V freewheeling diode. It has a built-in high-voltage power circuit to supply power to itself without any startup resistor or 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 SDH775XP works in inductor current boundary conduction mode, it uses a unique high-precision current sense technology, combined with internal compensation to achieve high constant current accuracy and excellent line/load regulation.
The SDH775XP provides various protections, such as output short circuit protection, cycle-by-cycle over current protection, over temperature regulation, and open circuit protection for sensing resistor, which greatly improves the safety and reliability of the system.
