Infineon IDP2303 120W开关电源解决方案
Infineon公司的IDP2303是集成了浮点高边驱动器和600V起动单元的多模式PFC和LLC控制器,数字引擎为多模式工作提供先进算法,在整个负载范围内支持最高的效率,主要用在75W到300W的LCD-TV以及通用的开关电源(SMPS).本文介绍了IDP2303产品亮点和主要特性,典型应用电路图以及采用IDP2303的120 W 24 V 3.5 A 12 V 3 A SMPS演示板主要特性与指标,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..
