Description

• Parameters: NON-ISOLATED BUCK LED CONSTANT CURRENT DRIVER IC
• Description: The SDH771XN is a high accuracy 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 SDH771XN integrates high-voltage power supply circuit, it is able to supply power to itself without any startup resistor and auxiliary winding, and at the same time, a conventional external power supply capacitor is omitted, which greatly shortens the startup time as well as saves the system cost. The SDH771X
• Features: Available 500V high voltage power MOSFET in one package with stable performance Integrated high-voltage power supply, without the need of startup resistor and VCC capacitor Accurate constant current threshold (<±3%) Output short/open circuit protection Open circuit protection threshold value external adjusted Over temperature regulation Cycle-by-cycle over current protection No auxiliary winding Ordering Information Product Name • Applications: LED Lighting, Power Supply
