ICL8820 Overview
ICL88xx Datasheet for ICL8800, ICL8810 and ICL8820.
ICL8820 Key Features
- Constant voltage (CV) output flyback topology
- Optimized for high power factor (HPF) flyback topology with secondary side regulation (SSR) operation
- Supports universal input voltage (90 VAC to 300 VAC, 45 Hz to 66 Hz) and DC input voltage operation
- High power factor and low THD, across wide AC input voltage and output load range
- Quasi-resonant mode (QRM) operation with continuous conduction mode (CCM)-prevention and valley
- Adjustable on-time mapping at valley changing position, for the desired maximum operating switching
- Adjustable maximum on-time
- limits input power and current allowing safe-operation under low line
- prehensive set of protections
- internal overtemperature protection (OTP)
ICL8820 Applications
- Battery charging up to 125 W
