SY5810
The SY5810 is a single stage Flyback and PFC controller targeting at LED lighting applications. It is a primary side controller without applying any secondary feedback circuit for low cost, and drives the Flyback converter in the quasi-resonant mode to achieve higher efficiency. It keeps the Flyback converter in constant on time operation to achieve high power factor.
*Compact package: SOT23-6
率高PFC,SY5810,1. 集成PFC,功率因數(shù)很高, 隔離效率大部分情況下在88%、89%,高達(dá)92%,PFC 0.95到0.99, 2.原邊控制QR模式,省去光耦和相關(guān)電路,降低BOM cost 3. 獨(dú)特的MOSFET控制技術(shù),對(duì)MOSFET和快恢復(fù)二極管的要求降低很多,不必選擇昂貴的MOSFET和二極管, 高功率因數(shù)、精度3%以內(nèi),QR模式、 率、穩(wěn)定性高、一致性好、外圍器件少、空間小、性價(jià)比高。
