Categories: AC DC Converters, Offline Switches
Quality Control: Learn More
Fairchild Semiconductor's FSFR-US series FSFR2100USL is an advanced offline switching controller designed for half-bridge converter topologies. This 9-SIP (L forming) packaged component supports switching frequencies up to 300kHz, enabling highly efficient power conversion up to 400W. Key features include internal switches, frequency control, and a 50% duty cycle capability. The device incorporates robust fault protection mechanisms, including current limiting, over-temperature, and over-voltage protection, ensuring reliable operation in demanding environments. With an operating temperature range of -40°C to 130°C (TJ) and a breakdown voltage of 500V, the FSFR2100USL is suitable for applications in power supplies, consumer electronics, and industrial automation. The through-hole mounting type and isolated output are critical for system integration.
