IR2161STRPBF Infineon PFC/PWM Controller | 8-SOIC | 500V, 50kHz

Product Overview

The IR2161STRPBF is a highly integrated PFC (Power Factor Correction) and PWM (Pulse Width Modulation) combo controller from Infineon Technologies. Designed for high-performance power supply applications, this device combines a critical conduction mode (CrCM) PFC controller with a half-bridge PWM controller in a compact 8-SOIC package. It operates at a fixed frequency of 50kHz and features a high-voltage startup cell (500V) for efficient power management. The IR2161STRPBF is ideal for applications requiring high power density, low standby power, and compliance with harmonic distortion standards.
