Fairchild FL103初级调整的LED照明解决方案

Fairchild公司的FL103是用于LED照明的第三代初级调整(PSR)PWM控制器,采用TRUECURRENT拓扑可使具有精密的恒流(CC)调整,并简化LED照明电路,和通常设计或线性变压器相比,具有更低的成本和更小的体积,其待机功耗小于30mW,主要用在LED照明和通用反激转换器.本文介绍了FL103主要特性,方框图, 典型应用电路图和采用FL103M初级调整(PSR)的LED灯控制电路设计电路.

FL103: Primary-Side-Regulation PWM Controller for LED Illumination

This third-generation Primary-Side-Regulation (PSR) and highly integrated PWM controller provides features to enhance the performance of LED illumination.

The proprietary topology, TRUECURRENT™, enables precise CC regulation and simplified circuit for LED illumination applications. The result is lower-cost and smaller LED lighting compared to a conventional design or a linear transformer.

To minimize standby power consumption, the proprietary green-mode function provides off-time modulation to linearly decrease PWM frequency under light-load conditions. Green mode assists the power supply in meeting the power conservation requirements.By using the FL103, LED illumination can be implemented with few external components and minimized cost.

FL103主要特性:

 Low Standby Power: < 30mW

 High-Voltage Startup
