Description

  • TND398-D, Describes a built-and-tested, Green Point solution for a 13 W nominal constant current power factor corrected offline LED driver. This is intended for solid state lighting (SSL) applications such as commercial and residential LED downlights and spotlights that require high efficiency, power factor correction and TRIAC dimming control. The power supply design is built around ON Semiconductor's NCL30000 critical conduction mode fixed on-time flyback controller. The secondary side regulates a 350 mA constant current capable of driving a string of 1 W phosphor converted white LEDs
