Product Summary
The 3BR2565JF is a 650V Off-Line SMPS Current Mode Controller. It has a wide Vcc range to 25V by adopting the BiCMOS technology. With the merit of Active Burst Mode, it can achieve the lowest Standby Power Requirements (<100mW) at no load and Vin = 270VAC. Since the 3BR2565JF is always active during the Active Burst Mode, it is an immediate response on load jumps and leads to <1% voltage ripple voltage at output. In case of protection for Overtemperature, Overvoltage, Open loop and Overload conditions, it would enter Auto Restart Mode.
