Overview
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.
