1.TEA2261功能TEA2261是飞利浦公司生产的彩色电视机开关电源专用集成电路。该集成电路主要包括:振荡电路、过流、过压、稳压控制等电路。由于TEA2261性能稳定可靠,外接元件少,所以在国内外彩色电视机中应用较广。虽然不同彩电生产厂家在设计理念上存在差异,出现了采用TEA2261设计的开关电源在电路结构上有所不同,但并不能改变TEA2261的固有功能和对该集成电路故障的判定。
1. TEA2261 function TEA2261 is a Philips color TV switching power supply ASIC. The integrated circuit includes: oscillator circuit, over-current, over-voltage, voltage regulator control circuit. As TEA2261 stable and reliable performance, fewer external components, so widely used in domestic and international color TV sets. Although different color TV manufacturers in the design concept there are differences in the emergence of TEA2261 designed switching power supply in the circuit structure is different, but does not change the TEA2261’s inherent features and determine the integrated circuit failure.
