Datasheet Low Noise Quasi-Resonant Control DC/DC converter IC for AC/DC Converter BD7682FJ-LB BD7683FJ-LB BD7684FJ-LB BD7685FJ-LB General Description This is the product guarantees long time support in the Industrial market. BD768xFJ series is a Quasi-resonant controller type DC/DC converters that provide an optimum system for all products that include an electrical outlet. Quasi-resonant operation enables soft switching and helps to keep EMI low. Design with a high degree of flexibility is achieved with switching MOSFETs and current detection resistors as external devices. The built-in brown out function monitors the input voltage as part of system optimization. The burst mode function reduces input power at low power.
