NXP 公司的UBA2211 是用于节能灯CFL的半桥配置的电源集成电路,火线电压220VAC,最大起辉电流有0.9A,1.35A 和1.85A三个型号。具有预热状态和饱和电流保护,RMS电流控制和超温保护以及容性模式保护。主要用在功率高达25W室内外荧光灯(CFL)。本文介绍了UBA2211主要特性和优势以及专利技术,方框图,应用电路图和230V 12W CFL UBA2211演示板主要指标,电路图和材料清单(BOM)。
UBA2211:Half-bridge power IC family for CFL lamps
The UBA2211 family of integrated circuits are a range of high voltage monolithic ICs for driving Compact Fluorescent Lamps (CFL) in half-bridge configurations. The family is specifically designed to provide easy integration of lamp loads across a range of burner power and mains voltages.
Patented technologies and integrated protection types:
• Preheat state:
– Preheat applications: Adjustable current controlled preheat mode technology enables the preheat time (tph) and preheat current to be set. This mode is triggered during start up.
– Non-preheat applications: Glow-time control minimizes electrode damage just after ignition of the lamp.
