Datasheet Low Consumption and High Accuracy Shunt Regulator Built-in High Efficiency and Low Standby Power, CCM corresponding Secondary Side Synchronous Rectification Controller IC BM1R00146F BM1R00147F BM1R00148F BM1R00149F BM1R00150F General Description Key Specifications BM1R00146F-150F are synchronous rectification Input Voltage Range: 2.7V to 32V controller to be used in the secondary-side output. It Circuit Current (No Switching): 800A(Typ) has a built-in low consumption and high accuracy Circuit Current (Auto Shutdown) : 120A (Typ) shunt regulator, which significantly reduces standby DRAIN Terminal Absolute Voltage: 120V power. The shunt regulator is constructed in a Operating Temperature Range: -40C to +105C completely independent chip that enables it to operate as a GND reference even when used in high side. Package W(Typ) x D(Typ) x H(Max) 5.00mm x 6.20mm x 1.71mm At continuous mode operation, further space saving can be realized when operating without the input switching synchronizing signal of the primary side. BM1R00146F-150F 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.
