[原创] Infineon IDP2303120W PFC+LLC转换器参考设计

Infineon公司的IDP2303是多模式PFC和LLC控制器,集成的数字引擎提供用于多模式工作的先进算法,在整个负载范围内支持最高的效率.器件还集成了高压600V起动单元,其先进的突发模式可获得低的待机功耗.UART接口可用来通信和在电路中配置.主要用在LCD TV电源,通用开关电源(SMPS)和电源适配器.本文介绍了IDP2303产品亮点和主要特性,框图和应用电路,以及DEMO-IDP2303-120W PFC+LLC转换器主要指标,电路图,材料清单和PCB设计图.

The IDP2303 is a multi-mode PFC and LLC controller combined with a floating high side driver and a startup cell. Adigital engine provides advanced algorithms for multi-mode operation to support highest efficiency over the whole loadrange. A comprehensive and configurable protection feature set is implemented. Only a minimum of externalcomponents are required with the low pin count DSO-16 package. The integrated HV startup cell and advanced burstmode enable to achieve low stand-by power. In addition a one-time-programming (OTP) unit is integrated to provide awide set of configurable parameters that help to ease the design in phase.

IDP2303产品亮点:

• Integrated 600V startup cell
• Integrated floating driver based on coreless transformer technology
• Digital multi-mode operation for higher efficiency curve..
