1. Overview
The IRPLCFL5E reference design is an electronic ballast for driving 26W compact fluorescent
lamps from 220VAC. The circuit provides all of the necessary functions for preheat, ignition and on-
state operation of the lamp and also includes the EMI filter and the rectification stage. The circuit is
built around the IR2520D Ballast Control IC. The IR2520D provides adjustable preheat time, adjust-
able run frequency to set the lamp power, high starting frequency for soft start and to avoid lamp
flash, fault protection for open filament condition and failure to strike, low AC line protection and
auto-restart after line brownout conditions. The IR2520D is a low-cost solution specific for CFL
applications. The IR2520D has only 8 pins and allows the component count for the complete ballast
to be reduced down to 19 components.
