ManufacturerInfineon Technologies
CategoryPower Management ICs; PFC Controllers
DescriptionSingle-Stage Power Factor Correction (PFC) Controller, CRM, 500kHz, SOIC-8 Package

Product Overview

The IR1155STRPBF is a high-performance critical conduction mode (CRM) power factor correction controller optimized for high-efficiency AC-DC power supply designs. It integrates advanced control algorithms to achieve near-unity power factor and low total harmonic distortion (THD) across wide load ranges. The device features programmable switching frequency up to 500kHz, over-voltage protection, over-current protection, and under-voltage lockout for robust and reliable operation. With its compact design and high integration, it minimizes external components and reduces system cost. Housed in a space-saving SOIC-8 surface-mount package, it is ideal for consumer, industrial, and lighting power systems requiring high efficiency and compliance with power quality standards.
