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:

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
