Hi All,
There is no current shunt resistor which series into DC output side, how to achieve constant current source in this application?
how to design the transformer in PMP4530 application? Can I have to know the calculation for reference? I would like…

PMP4350, PMP4371是为大功率(>100 w) 通用LED照明设计的高效(> 94%)的AC/ DC高压单串输出解决方案。使用PFC加上LLC控制的拓扑结构,它可以在输出端支持PWM调光和模拟调光。相较于传统的三级解决方案(PFC+DC/DC+Linear LED driver), 不仅结构简单(两级),效率提高, 成本上也得到了极大的优化。这两款设计非常适合电视LED背光…
