High-voltage power IC from NXP drives CFL with quick warm-up and dimming feature

NXP has made available of UBA2028, an integrated high-voltage power IC that drives dimmable Compact Fluorescent Lamp (CFL) with quick warm-up and dimming capabilities down to 10 percent of full light intensity. The NXP CFL driver IC enabling more compact designs, high efficient power conversion, and extended CFL lifetimes beyond 15,000 hours.

The UBA2028 IC includes a 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 detection and protection circuits.

The key features of the UBA2028 include,

Two internal 600 V, 3 O (max) MOSFETs
For steady state currents, support up to 280 mA
For ignition currents, support up to 1.5 A
Adjustable preheat time and current
Advanced dimming (Phase-cut and 1-10 V)
Current-controlled operation
Single ignition attempt
Adaptive non-overlap time control and integrated bootstrap diodes
Integrated high-voltage level-shift function
Capacitive mode protection, lamp failure detection
Power-down in case of lamp failure

"Consumers have been understandably frustrated with the quality of light available from most CFLs on the market today. With the UBA2028, NXP is helping to change the way people perceive and experience compact fluorescent lighting," said Jacques le Berre, director of marketing and business development for lighting solutions, NXP Semiconductors. "By enabling 'true dimming,' we are enabling lighting manufacturers to raise the bar and create higher-quality CFLs that are indistinguishable from incandescent bulbs. The net result is that consumers who want to take advantage of the tremendous energy savings offered by CFLs will no longer have to sacrifice the quality of light they enjoy in their homes."
