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
and a ballast control circuit using the IR2153
for controlling 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’
time to market.
