NXP Semiconductors has announced the introduction of the fully integrated high-voltage power supply integrated circuit UBA2028, which is a dedicated driver chip for Compact Fluorescent Lamps (CFL), which helps lighting manufacturers produce high-quality CFLs. product.
The UBA2028 provides fast warm-up and a dimming capability that is adjustable to a minimum of 10% of full light intensity, allowing fluorescent lamps to perform well against incandescent lamps. This NXP's latest CFL driver chip will further optimize power-saving design, improve power conversion efficiency, and achieve an ultra-long CFL life of more than 15,000 hours.
The 600V power integrated circuit chip UBA2028 integrates a 3Ω switch to support the drive and control of 21W dimming CFL products. The chip includes a half-bridge power circuit, a dimmer, a high voltage electric transfer circuit, a vibrator, a lamp voltage monitor, a current control unit, a timer, and a detection and protection circuit.
All NXP CFL driver chips, including the UBA2028, are designed to help lighting manufacturers produce higher quality energy-saving lamp products. By replacing the standard discrete architecture of electronic rectifiers with integrated chip solutions, lighting operators can meet more stringent requirements and introduce more popular CFL products.
The NXP U282028 has a "true dimming" function that allows for smoother lighting adjustments without flicker or noise. In addition, the highly integrated chip features further reduce the size of the CFL, making it suitable for smaller shade sizes, providing new possibilities for lampshade design.
