Its comprehensive set of protection features and bottom-up design ensure easy design-in and require a minimum number of external components, thus having a perfect price/performance ratio. The controller is optimized as a secondary-side regulated (SSR) constant voltage (CV) output flyback controller and is also well suited for primary-side regulation (PSR). Therefore, ICL8810 ensures flexibility for many applications.
ICL8810 is the advanced variant of the ICL88xx family. With its additionally integrated burst mode, the controller enables a very low stand-by power < 100mW. Consequently, more power budget for additional components can be used and ICL8810 is ideally suited for smart lighting applications in connection with microcontrollers.
