Description

The IR1155SPBF is a 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 to 264VAC input line voltage range. Switching frequency can be programmed to anywhere between 48 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, VCC UVLO, soft-start and micropower startup/sleep-mode with IC current consumption less than 200µA.
