600W Non-isolated PWM Dimming LED Driver with KP1469


This DEMO board is a high performance nonisolated 600W constant current LED driver which is controlled by KP1469.Besides the multi-protection function (OVP, SCP, OTP), this demo also has very good efficiency, load regulation, low standby power loss and wide dimming range.

After combining this non-isolated buck circuit with front-end PFC (KP2822) and dimming interface (KP1402), it can form a complete two-stage intelligent dimming solution, achieving high PF, low THD, and flicker-free dimming. It is applied in highpower LED lightings such as high-pole lamps and plant lighting.
