FSFR2100XS Description

Short technical summary and product information.

The FSFR2100XS is a power switch IC from ON Semiconductor, specifically designed for high-efficiency half-bridge resonant converter topologies. It integrates essential components like power MOSFETs with fast-recovery body diodes, a high-side gate-drive circuit, an accurate current-controlled oscillator, and built-in protection functions including Over-Voltage Protection (OVP), Over-Current Protection (OCP), Abnormal Over-Current Protection (AOCP), and Internal Thermal Shutdown (TSD).

 

This device supports variable frequency control with a 50% duty cycle, enabling Zero Voltage Switching (ZVS) for reduced switching losses and improved efficiency. It can operate at frequencies up to 300 kHz and provides up to 400 W of output power with heatsinking. The operating temperature range is from -40°C to 130°C (TJ).

 

The FSFR2100XS is packaged in a 9-SIP configuration and is designed for through-hole mounting. Its integrated features simplify design and improve productivity for applications such as PDP and LCD TVs, desktop PCs, servers, adapters, and telecom power supplies.
