FAN7544-FAN7544N
Electronic Ballast Controller
Features Low Start-up and Operating Current : 140µA, 6.5mA Under Voltage Lock Out With 1.9V of Hysteresis 600mA of Totem Pole Output with High State Clamp Trimmed 1.5% Internal Bandgap Reference Programmable Preheat Time & Frequency Programmable Run Frequency High Accuracy Oscillator
DescriptionsThe FAN7544 provides simple and high performance elec-
tronic 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 fre-
quency 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.
