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.
