RED2822 is an advanced resonant controller IC for high efficiency CC LED drivers with flicker free linear dimming. It is suitable for low-cost passive PFC systems up to 45W and high power active PFC systems up to 250W.
Advanced Resonant Controller IC for high efficiency LED drivers. Upgrade to RED2821 Primary-side Constant Current regulation reduces component count and enables easy interfacing with digital control (Bluetooth, Zigbee, DALI MCU, PWM) Optimised for: o Passive PFC LED drivers up to 45W o Active PFC LED drivers up to 200W. RED2822 works with any APFC controller IC 50% duty cycle, variable frequency control of resonant half-bridge +/-5% Primary Side Regulation of LED current and voltage with no Flicker Protection modes: a. Overload output including short-circuit b. No-Load Output c. Over-temperature foldback & shutdown Low standby power Small SO8 IC package
