Overview

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.
BD768xFJ series include various protection functions, such as a soft start function, burst function, per-cycle over-current limiter function, overvoltage protection function, overload protection function, and brown out function.
BD768xFJ series include a gate-clamp circuit for optimal driving SIC-MOSFET.
