IR1155S Overview
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 ponent count, PCB area and design time as pared 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...
