Datasheet for ICL8800, ICL8810 and ICL8820
Feature list
The ICL88xx family of single stage flyback controllers for constant voltage output is tailored for LED lighting
applications to meet the required performance. They oer power factor correction (PFC) and low total
harmonic distortion (THD) from low to full load conditions.
General features ICL8800, ICL8810, ICL8820
• Constant voltage (CV) output flyback topology with a feature set and operation targeting lighting
applications
• Optimized for PFC-flyback topologies with secondary side regulation (SSR) operation, primary side
regulation (PSR) possible
• Supports universal input voltage (90 V
AC
to 300 V
AC
, 45 Hz to 66 Hz) and DC input voltage operation
• High power factor low THD performance across wide load and input AC line range
• Quasi-resonant operation with continuous conduction mode (CCM)-prevention and valley switching
discontinuous conduction mode (DCM) in mid to light load
• Adjustable max on-time – limits input power and current allowing safe-operation under low line condition
• Comprehensive set of protections: Internal overtemperature protection (OTP), output overvoltage
protection (OVP), overcurrent protection (OCP), brown-in and brownout protection, open loop protection,
input overvoltage protection

Description
The ICL8800, ICL8810 and ICL8820 is a voltage mode controller for flyback topologies operating in quasi-
resonant mode and valley switching DCM. It is designed for low and high power lumen LED driver, requiring
high power factor and eiciency. The flyback controller is capable of controlling SSR-CV an PSR-CV topologies.
Oering a wide usage in low cost applications where a PFC functionality in dual stage topologies is required.
For lighting applications, the IC oers a wide power range as well as a comprehensive set of protections,
including a power limitation. The IC is easy to design in and requires a minimum number of external
components.
The gate driver current enables reasonable designs up to 125 W with state-of-the-art MOSFETs. The system
performance and eiciency, especially in light load conditions, can be optimized using Infineon CoolMOS
™
P7
power MOSFETs.
ICL8810 and ICL8820
The integrated burst mode function allows designs with a very low standby power consumption and small
output ripple during standby mode and very light loads.
ICL8820
The jitter function eases the design of emergency lighting LED drivers without additional circuitry to improve
EMI performance.
