FSL136HRLX

FSL136HRLX Description

The FSL136HRLX from onsemi is a high-performance offline switch designed for flyback topology applications, delivering up to 26W of power. Part of the FPS™ (Fairchild Power Switch) series, it integrates an internal 650V MOSFET and operates at a switching frequency of 100kHz, ensuring efficient power conversion. With a wide input voltage range (8V–26V) and a start-up voltage of 12V, it is optimized for isolated power supplies. The device is RoHS3 compliant and REACH unaffected, meeting stringent environmental standards. Packaged in an 8-pin LSOP and available in Tape & Reel (TR), it is suitable for surface-mount assembly in compact designs.

FSL136HRLX Features

• Integrated 650V MOSFET with 77% duty cycle for robust performance.
• Comprehensive fault protection: Current limiting, over-voltage, over-temperature, short-circuit, and overload protection.
• High efficiency with 100kHz switching frequency, reducing thermal stress.
• Wide supply voltage range (8V–26V) for versatile applications.
• Isolated output for enhanced safety in offline power supplies.
• Compact 8LSOP package with MSL 3 (168 hours) moisture sensitivity, ideal for automated PCB assembly.
• Compliant with RoHS3 and REACH, ensuring environmental safety.
