Description
The IRPLLNR1 is a high efficiency, high
power factor, non-dimmable electronic ballast
designed for linear fluorescent lamp types.
The design contains an active power factor
correction circuit for universal voltage input
as well as a ballast control circuit using the
IR2153 for managing the lamp. Other
features include EMI filtering, transient
protection and lamp fault protection. The
IRPLLNR1 is intended as a reference design
to be used as development tool to speed up
customers鈥?time to market.
