[原创] Infineon IDP2308 120W开关电源(SMPS)解决方案

Infineon公司的IDP2308是多模式PFC和LLC控制器,组合了浮动高边驱动器和起动单元.数字引擎提供多模式运行的先进算法,支持整个负载范围内的最高效率,并具有综合和可配置的保护特性,集成的高压(HV)600V起动单元和先进的突发模式能获得低待机功耗.此外,集成的一次性编程(OTP)单元提供大范围可配置参数,使得容易设计.IDP2308书数字组合LLC控制器,支持多模式PFC和半桥LLC级的应用拓扑.多功能引脚保证了应用时非常低的元件数量.器件的UART接口用来通信和在电路配置.主要用在LCD-TV 75W ~ 300W和通用开关电源(SMPS).本文介绍了IDP2308产品亮点和主要特性,框图和典型应用图,以及DEMO-IDP2308-120W PFC+LLC转换器主要指标,电路图,材料清单和PCB设计图.

The IDP2308 is a multi-mode PFC and LLC controller combined with a floating high side driver and a startup cell. A digital engine provides advanced algorithms for multi-mode operation to support highest efficiency over the whole load range. A comprehensive and configurable protection feature set is implemented. Only a minimum of external components are required with the low pin count DSO-14 package. The integrated HV startup cell and advanced burst mode enable to achieve low stand-by power. In addition a one-time-programming (OTP) unit is integrated to provide a wide set of configurable parameters that help to ease the design in phase.
