Infineon ICL8820XUMA1 LED Driver IC, 8 → 24 V 8-Pin PG-DSO-8

The Infineon 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.

Soft-start to reduce stress during turn-on
External start-up circuit control signal with Vcc support in light load operation
Reduced gate driver output voltage during start-up sequence and burst mode allowing smaller Vcc cap
Burst mode for very light loads and low system standby power consumption
