BM1R00178F
High Efficiency, Low Standby Power and CCM Corresponding Secondary Side Synchronous Rectification Controller IC
BM1R00178F is synchronous rectification controller to be used in the secondary side output. It has a built-in low consumption and high accuracy shunt regulator, which reduces standby power. Since the shunt regulator is made up of completely independent chips, it can operate as a GND reference even when it is used with High Side. At continuous conduction mode (CCM) operation, further space saving can be realized when operating without the input switching synchronizing signal of the primary side. BM1R00178F also feature a wide operating supply voltage of 2.7V to 32V for various output applications. In addition, by adopting the high voltage 120V (Max) process, it is possible to monitor the drain voltage directly.
You can choose from a variety of power and topology evaluation boards.
