Product Summary
The 3BR1065JF 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 3BR1065JF 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.
