RED2601 is an advanced LLC Controller IC for high efficiency LED drivers, intended for two stage APFC + LLC LED drivers without flicker, universal mains input LED drivers or CC LED drivers up to 200W.
• Advanced LLC Controller IC for high efficiency LED drivers • For RediSem’s low-cost LLC converter topology with bipolar transistors • Optimized for 2-stage LLC + APFC LED drivers. RED2601 works with any APFC controller IC • PSR - +/-5% Primary Side Regulation of LED current and voltage with no flicker • 50% duty cycle, variable frequency control of resonant half-bridge • Automatic dead-time control and capacitive mode protection • Protection modes: a. Overload b. No-Load c. Internal Over-temperature d. External Over-temperature (NTC) • Low output capacitance allows live LED connection • No flicker - zero output current ripple
