The FAN7544 provides simple and high performance electronic ballast control functions. The FAN7544 is optimized for electronic ballast requiring a minimum board area, by reducing component counts and lowering power dissipation. The features include programmable preheating time and frequency and programmable run frequency. The initial pre-heating time and frequency can be adjusted according to the types of lamps using the CPH, CT and RPH. Output gate driver circuit clamps power MOSFET gate voltage to the supply voltage.
