BM1R00146F is a synchronous rectification controller to be used in the secondary-side output. It has a built-in ultra-low consumption and high accuracy shunt regulator, which significantly reduces standby power. The shunt regulator is constructed in a completely independent chip that enables it to operate as a GND reference even when used in high side. At continuous mode operation, further space saving can be realized when operating without the input switching synchronizing signal of the primary side. BM1R00128F also features a wide operating power supply voltage range of 2.7V to 32V for various output applications. Finally, by adopting the high-voltage 120V process, it is possible to monitor the drain voltage directly."You can choose from a variety of power and topologyevaluation boards.

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 topologyevaluation boards.

This IC outputs the AC voltage zero cross timing detection with high accuracy. By eliminating the need for photocoupler and external components required in conventional applications, it is possible to reduce the number of parts drastically and realize compact and highly reliable power supply applications. In addition, this IC can reduce standby power largely in comparison with an existing photocoupler control. Furthermore, this IC can handle both normal and double rectification by the original system.
