Silan Microelectronics SD670X_Datasheet NON-ISOLATED BUCK LED LIGHTING DRIVE IC WITH LOW POWER ANG HIGH CONSTANT CURRENT ACCURACY DESCRIPTION SD670XS is designed for non-isolated LED driving with floating Buck structure, and high constant current accuracy and high linear/load regulation available with assistant of special sense technology. SD670XS integrates various protections, such as output open circuit protection, cycle-by-cycle current limit protection and over temperature protection. The start-up current and operating current are low and highlight LED can be driven with high efficiency in full range (85VAC~265VAC). SD670XS integrates high voltage power MOSFET, reducing the system cost and the whole volume. SOP-7-225-1.27 FEATURES  Built-in 500V high voltage power MOSFET  Constant current with high accuracy for LED (<±3%)  Output open circuit protection  CS open circuit protection  VCC undervoltage protection  Over temperature protection  Cycle-by-cycle ...
