The Infineon Technologies IR1155STRPBF is a Power Factor Correction (PFC) Integrated Circuit (IC) utilizing an "One Cycle Control" technique. It is designed for continuous conduction mode (CCM) boost type PFC converters and operates over an 85-264VAC input line voltage range. The switching frequency is programmable between 48kHz and 200kHz, allowing for application-specific optimization.
Key features include output overvoltage protection, open loop protection, cycle-by-cycle peak current limit, and VCC undervoltage lockout. It also offers programmable soft start and micropower startup/sleep modes, with current consumption less than 200µA in sleep mode. The IC is housed in an 8-SOIC package and is suitable for surface mounting.
This PFC IC is engineered to provide high power factor, low total harmonic distortion (THD), and excellent DC bus regulation. Its design aims to reduce component count, PCB area, and design time compared to traditional solutions. The operating temperature range is -25°C to 125°C, with a supply voltage requirement of 12V to 19V.
