The IRPLDIM4E Reference Design is a miniature dimmable electronic ballast for driving 26W compact fluorescent lamps from a 220VAC line. The circuit provides all of the necessary functions for preheat, ignition, and dimming control of the lamp and also includes the EMI filter and AC rectification stage. The ballast size is 1.42in x 2.44in (36mm x 62mm). The circuit is designed around the IRS2530D(S)PbF DIM8TM Ballast Control IC. The IRS2530D includes adjustable preheat time, frequency sweeping for filament preheating and lamp ignition, a dimming reference and feedback input, a high soft-start frequency to avoid lamp flash, lamp and ballast fault protection for open filament condition, failure to strike, and no lamp fault conditions, automatic restart during lamp exchange, and, low AC line protection. The IRS2530D is simple to use, has only 8 pins, and drastically reduces component count for a complete dimming solution.
