Features
• PFC IC with IR proprietary “One Cycle Control”
• Continuous conduction mode boost type PFC
• Programmable switching frequency (48k-200kHz)
• Average current mode control
• Output overvoltage protection
• Open loop protection
• Cycle by cycle peak current limit
Description
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.
In addition, IR1155 offers several advanced system-enabling and protective
features such as dedicated pin for over voltage protection, cycle by cycle
peak current limitation, open loop protection, V
micropower startup/sleep-mode with IC current consumption less than
200µA. The sleep mode, invoked by pulling the OVP/EN pin low, enables
compliance with standby power requirements mandated by regulations
such as Energy Star, Green Power, Blue Angel etc.
