FSFR2100 is an integrated Pulse-Frequency-Modulation (PFM) controller and MOSFETs especially designed for Zero-Voltage-Switching (ZVS) resonant half-bridge converter topologies.

• Variable frequency control with 50% duty cycle for half-bridge resonant converter topology
• High efficiency through zero voltage switching (ZVS)
• Internal SuperFETs with fast recovery type body diode (t_rr=120ns)
• Fixed dead time (350ns)
• Up to 300kHz operating frequency
• Pulse skipping for frequency limit (programmable) at light-load condition
• Simple remote ON/OFF control
• Various protection functions: Over-Voltage Protection (OVP), Overload Protection (OLP), Over-Current Protection (OCP), Abnormal Over-Current Protection (AOCP), Internal Thermal Shutdown (TSD)
