Low Noise Quasi-Resonant Control DC/DC converter IC for AC/DC Converter - BD7682FJ-LB

The BD7682FJ-LB is a quasi-resonant controller-type DC/DC converter optimized for products equipped with an electrical outlet. Quasi-resonant operation enables soft switching and helps to keep EMI low, while utilizing an external switching MOSFET and current detection resistor provides greater design flexibility. Additional features include a brown out function that monitors the input voltage for system optimization and a burst mode function for reducing power during light loads. Multiple protection functions are also incorporated to provide greater reliability, such as soft start, burst mode, per-cycle overcurrent limiter, and overvoltage/overload protection. A gate clamp circuit is built in as well for optimizing SiC MOSFET drive.

For driving SiC (Silicon Carbide) MOSFET. The evaluation board outputs 24 V voltage from the input of 300 Vdc to 900 Vdc. The output current supplies up to 1 A.
BD7682FJ-EVK-301 Evaluation Board User's Guide
 
For driving SiC (Silicon Carbide) MOSFET. This board is able to operate with both AC and DC input voltages. It is therefore possible to derive the power directly from the grid or from the system DC link, after the PFC stage. In case of AC input, the accepted input voltage range goes from 210 VAC to 480 VAC. In case of DC input, the input range goes from 300 VDC to 900 VDC.
