　　UBA2028: 600 V dimmable power IC for compact fluorescent lamps

　　The UBA2028 is a high voltage power IC that drives and controls electronically ballasted

　　Compact Fluorescent Lamps (CFLs). The IC includes a Metal-Oxide-Semiconductor

　　Transistor (MOST) half-bridge power circuit, a dimming function, a high voltage level shift

　　circuit, an oscillator function, a lamp voltage monitor, a current control function, a timer

　　function and various protections.　　

　　UBA2028主要特性和优势:

　　 Two internal 600 V, 3 Ω max MOST half-bridge power circuits

　　 For steady state currents up to 280 mA

　　 For ignition currents up to 1.5 A

　　 Adjustable preheat time

　　 Adjustable preheat current

　　 Current controlled operating

　　 Single ignition attempt

　　 Adaptive non-overlap time control

　　 Integrated high voltage level shift function

　　 Power-down function

　　 Protection against lamp failures or lamp removal

　　 Capacitive mode protection

    UBA2028应用:
　　5 W to 25 W dimmable CFLs, provided that the maximum junction temperature is not exceeded.
