IR IR1155 300W能源之星电源参考设计方案

IR 公司的IR1155是采用IR所有权的“一周期控制”（OCC）技术的微PFC器件，采用连续导通模式，可编程开关频率48kHz-200kHz，输入电压85-264VAC，满足能源之星，绿色能源和蓝色天使等电源标准。本文介绍了IR1155 主要特性，方框图，应用图以及IRAC1155-300W 参考设计主要特性指标，电路图和材料清单。

The μPFC IR1155 power factor correction IC, based on IR proprietary "One Cycle Control" (OCC) technique, provides for high PF, low THD and excellent DC Bus regulation while enabling drastic reduction in component count, PCB area and design time as compared to traditional solutions. The IC is designed to operate in continuous conduction mode Boost PFC converters with average current mode control over 85-264VAC input line voltage range. Switching frequency can be programmed to anywhere between 48kHz to 200kHz based on the specific application requirement.
