随着人们对照明品质要求的提升，对照明灯具产品无频闪要求越来越多。在商业照明领域，隔离低谐波无频闪要求越发普及，面板灯及轨道灯等需求更明显，原有使用LLC 方案，单极APFC 加去频闪电路使用也比较多。随着集成MOS 的升压 IC 的普及以及升压线路成本的优化，升压加反激电路的两级方案整体性价比优势越发明显，且两级方案整体电气性能及可靠性更好。 为了适应市场的需求，晶丰明源为您带来 BP2606C+BP3337D解决方案。 BP2606C+BP3337D 典型应用原理图 升压及反激都是集成MOS，应用成熟简单可靠性高。高效率，相对消纹波电路没有极热元件及比较大的输出电解。相对LLC 方案有更好的输入线性调整率及输出负载调整率。整体设计方案成熟稳定。 BP2606C+BP3337D 方案特点 1、高功率因素低谐波，THD<输出无频闪，效率达Vac； 3、简单的变压器结构，顺绕法生产简单成本低； 4、升压及反激芯片温升低，无需外加散热器。 典型应用方案 输入电压：198Vac~264Vac 输出电压：40Vdc 输出电流：1.05A
Along with the people, to the promotion of lighting quality requirement for lighting products no stroboscopic requirements more and more. In the field of commercial lighting, isolation low harmonic no stroboscopic requirements increasingly, panel light and track light and so on demand more apparent, the original use LLC, single-stage APFC is added to the frequency of lightning road use. With the popularity of integrated MOS step-up IC and booster circuit cost optimization, booster and flyback circuit scheme of two levels of overall price advantage more obvious, and the two-stage plan overall better electrical performance and reliability. In order to meet the demand of the market, crystal FengMingYuan bring BP2606C + BP3337D solutions for you. BP2606C + BP3337D principle diagram of the typical application of booster and flyback are integrated MOS, mature application simple and high reliability. High efficiency, relative ripple elimination circuit without extremely hot components and larger output electrolysis. Relative LLC scheme has better input linear regulation and output load regulation. The overall design scheme of mature and stable. BP2606C + BP3337D scheme features 1, high power factor, low harmonic, THD <utput, no stroboscopic, efficiency up t vac. 3, simple transformer structure, along the winding simple production, low cost; 4, booster and flyback chip is low temperature, without additional radiator. Typical application solutions as the input voltage: 198 vac ~ 264 vac output voltage: : 40 VDC output current 1.05 A
