ICL8820XUMA1 Single flyback LED controller, 150KHZ, burst mode, SO-8

ICL8800, ICL8810 and ICL8820 Single-stage flyback LED controller for constant voltage output

Description The ICL8800, ICL8810 and ICL8820 is a voltage mode controller for flyback topologies operating in quasiresonant mode and valley switching DCM. It is designed for low and high power lumen LED driver, requiring high power factor and efficiency. The flyback controller is capable of controlling SSR-CV an PSR-CV topologies. Offering a wide usage in low cost applications where a PFC functionality in dual stage topologies is required. For lighting applications, the IC offers 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 efficiency, 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.

Features The ICL88xx family of single stage flyback controllers for constant voltage output is tailored for LED lighting applications to meet the required performance. They offer power factor correction (PFC) and low total harmonic distortion (THD) from low to full load conditions.
