RED2821AD Description

Short technical summary and product information.

The REDISEM RED2821AD is an advanced resonant controller IC engineered for high-efficiency LED driver applications. It is intended for use in two-stage linearly dimmable LED drivers without flicker, universal mains input LED drivers, and Constant Current (CC) LED drivers up to 200W.

 

Key features include a DIM input for linear dimming down to 10% load and optimized performance for 2-stage Power Factor Correction (PFC) and resonant LED drivers. The RED2821AD works with any APFC controller IC. It provides +/-5% primary side regulation of LED current and voltage with no flicker.

 

The device utilizes a 50% duty cycle, variable frequency control for resonant half-bridge operation. It incorporates protection modes for short-circuit, no-load conditions, and internal over-temperature.

 

Packaged in an SO8 surface-mount package and supplied on tape and reel, the RED2821AD is suitable for various LED power supply designs requiring high efficiency and low flicker.
