650-V green mode buck switches offer high power efficiency with system design scalability

Fairchild Semiconductor’s FSL306 and FSL336 650 V Green Mode AC Buck Switches offer burst-mode operation with the low available operating current (250 μA) that helps to reduce standby mode power consumption for increased energy efficiency. Power scalability from 0.5 W to 3 W (FSL306) through the adjustable current limit pin helps simplify designs and reduce design time. The switches provide high reliability through protection features such as a Safe Auto Restart Mode. After a fault condition, the switch waits 650 ms before restarting. This feature reduces the stress on the system during a long-term fault, improving system reliability. These devices combine a PWM controller and a discrete MOSFET in a single package. A high-voltage regulator enables operation without the need for an auxiliary bias winding. Using a built-in error amplifier, the FSL306 and FSL336 provide direct feedback without a shunt regulator.
