目录产品概述 返回TOP The CXLE87156 is a single stage Flyback and PFC controller targeting at LED lighting applications with PWM/Analog dimming. 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.产品特点 返回TOP Primary side control eliminates the opto-coupler PWM or Analog Dimming Valley turn-on of the primary MOSFET to achieve low switching losses 0.3V primary current sense reference voltage leads to a lower sense resistance thus a lower conduction loss Internal high current MOSFET driver: 1A sourcing and 2A sinking Low start up current: 15uA typical Reliable short LED and Open LED protection Power factor >0.90 with single-stage conversion.(Analog dimming only) Compact package: SO8 应用范围 返回TOP LED lighting Down light Tube lamp PAR lamp Bulb lamp 技术规格书（产品PDF) 返回TOP 需要详细的PDF规格书请扫一扫微信联系我们，还可以获得免费样品以及技术支持！ a相关芯片选择指南 返回TOP 更多同类产品......
