FSFR2100USL

IC OFFLINE SW HALF-BRIDGE 9SIP

Manufacturer: Fairchild Semiconductor

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.

Integrated Circuit FAQs

An integrated circuit (IC) is a semiconductor chip that contains transistors, resistors, capacitors, and other electronic components on a single silicon substrate. ICs are the foundation of modern electronics and power devices such as smartphones, computers, automotive systems, and industrial equipment.

Integrated circuits work by routing electrical signals through microscopic semiconductor components fabricated onto a silicon chip. Depending on the design, ICs can process, amplify, store, or control electronic data.
