The FSFR1800HS is an advanced power switch designed for half-bridge resonant converters, featuring variable frequency control with a 50% duty cycle. It operates efficiently through zero voltage switching (ZVS), which minimizes switching losses and enhances overall efficiency. The device includes a built-in high-side gate driver and internal UniFETs with a fast-recovery body diode, ensuring reliable performance. This product supports an operating frequency of up to 600 kHz and incorporates several protection features, including over-voltage protection (OVP), over-current protection (OCP), abnormal over-current protection (AOCP), and internal thermal shutdown (TSD). The FSFR1800HS 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 format and operates within a temperature range of -40 to +130¬8C, with a maximum output power of 120 W without a heatsink and 260 W with a heatsink.
