[原创] Infineon IDP2303120W开关电源(SMPS)参考设计方案

Infineon公司的IDP2303是具有浮动高边驱动器和600V起动单元的多模式PFC和LLC控制器,其数字引擎提供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.主要用在75W-300W LCD-TV和通用的开关电源.本文介绍了IDP2303产品亮点和主要特性,框图,应用电路,以及120W开关电源(SMPS)演示板主要特性,指标和优势,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.
