FSFR1800XSL Description

Short technical summary and product information.

The FSFR1800XSL is a power switch from ON Semiconductor, specifically designed for high-efficiency half-bridge resonant converter topologies. This integrated solution simplifies design and enhances performance by combining power MOSFETs with fast-recovery body diodes, a high-side gate-drive circuit, a current-controlled oscillator, and built-in protection functions.

 

Key electrical specifications include a 50% duty cycle, operation up to 300kHz, and a power output of 260W. The device operates within a voltage range of 10V to 25V and features fault protection for current limiting, over-temperature, and over-voltage conditions. Its design leverages Zero Voltage Switching (ZVS) to significantly reduce switching losses and improve efficiency, while also minimizing switching noise.

 

This component is suitable for applications such as PDP and LCD TVs, desktop PCs, servers, adapters, and telecom power supplies. It is packaged in a 9-SIP (L forming) configuration and utilizes a Through Hole mounting type, making it suitable for robust board integration. The operating temperature range is -40°C to 130°C (TJ).
