L6585DE
The L6585DE integrates all the functions required to ensure correct operation
of electronic ballasts and high-brightness LED power supplies. This combo IC
generates more light from less energy, and is compliant with major safety and
power consumption regulations.
The L6585DE one-chip solution replaces two separate ICs (a PFC and a resonant
half bridge controller), greatly reducing design time and complexity, lowering costs
and providing a flexible solution.
High programmability and a wide range of protection features help customers
design cost-effective and reliable applications.
