HV power IC drives dimmable CFLs

The UBA2028 power IC enables lighting manufacturers to create high-quality CFLs that rival incandescent bulbs, with quick warmup and true dimming capabilities down to 10% of full light intensity. This 600-V device can drive and control dimmable CFL applications up to 21 W.

Features include 3-Ω integrated switches MOSFETs, single ignition attempt, a half-bridge power circuit, a high-voltage level-shift circuit, an oscillator function, a lamp voltage monitor, a current control function, a timer function, and detection and protection circuits. The part supports up to 280 mA, for steady-state currents and up to 1.5 A for ignition currents. ($1.75 ea/1,000 — available now.)
