Features
Description
IR1152 Application Diagram
• PFC IC with IR proprietary “One Cycle Control”
• Continuous conduction mode boost type PFC
• Fixed 66kHz switching frequency
• Average current mode control
• Input line sensed brownout protection
• Output overvoltage protection
• Open loop protection
• Cycle by cycle peak current limit
µPFC IR1152 power factor correction IC, based on IR proprietary "One
Cycle Control" (OCC) technique, provides for high PF 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 85-264VAC universal input, continuous
conduction mode Boost PFC at fixed 66kHz switching frequency.
IR1152 features include input-line sensed brown-out protection,
overvoltage protection, cycle by cycle peak current limit, open loop
protection, V
than 75µA. In addition, for standby power requirements, the IC can be
driven into a micropower sleep mode by pulling the OVP/EN pin low
where the current consumption is less than 75uA. The IR1152 is
available in SO-8 packages.
