2. Description

The IRPLDIM3 reference design kit consists of a high power factor wide input voltage range

dimming Fluorescent ballast, with a fully isolated 0 to 10V control interface, driving a single T5 28 W

rapid start linear lamp. The design contains an EMI filter, active power factor correction and a dimming

evaluation of the IRS2158D dimming ballast control IC, demonstrate PCB layout techniques and serve as

an aid in the development of production ballasts using the IRS2158D
