Infineon Technologies AG has introduced ICL8800ICL8810 and ICL8820 single-stage flyback LED controllers for constant output voltages. These ICs meet the necessary performance requirements for LED lighting applications, such as LED drivers and luminaires up to 125 W, smart lighting, and emergency luminaires. The ICL88xx family offers an external start-up circuit control signal for more flexibility and a cost-optimized bottom-up platform design for many applications.  It has a comprehensive set of protection features, including a power limitation and secondary side over-voltage protection. 


All the three variants are optimized as secondary-side regulated (SSR) constant voltage (CV) output flyback controllers and are also well suited for primary-side regulation (PSR). They feature critical conduction mode (CCM) and quasi-resonant mode (QRM) with smart valley hopping in order to achieve optimum efficiency and low electromagnetic interference (EMI) without compromising light quality. Moreover, the devices require a minimum number of external components and the gate driver current enables designs up to 125 W with state-of-the-art MOSFETs. 


ICL8810 is an advanced variant with an integrated burst mode that allows a very low standby power consumption of less than 100mW and flicker-free deep dimming down to 0.1 percent. This feature makes ICL8810 ideally suited for smart lighting applications in connection with microcontrollers.


ICL8820 is the fully-featured variant, additionally equipped with an integrated DC-input jitter function. It improves EMI performance and supports the fulfillment of EMI requirements in DC operation. ICL8820 eases EMI certification in the design of emergency lighting LED driver applications without additional circuitry, minimizing cost and effort.
