ROHM Semiconductor BM1R00030F
BM1R00xxxF 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.GENERAL DESCRIPTION
At continuous mode operation, further space saving can be realized when operating without the input switching synchronizing signal of the primary side. Key Specifications● Input Voltage Range: 2.7V to 32V
