BM1R00147F
High Efficiency and Low Standby Power, CCM corresponding Secondary Side Synchronous Rectification Controller IC
BM1R00147F 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."

- Evaluation Board - BM3G007MUV-EVK-001
This evaluation board outputs an isolated voltage of 12 V from an input of 90 Vac to 264 Vac, and the maximum output current is 8.3 A. It was developed mainly as a power supply for adapters. The average efficiency is 90.7% when VIN = 230V. The BM3G007MUV is GaN HEMT (650 V 70 mΩ), with integrated driver and protection circuitry. QR controllers for AC/DC power supplies use BM1Q021FJ.

- Evaluation Board - BM1R00147F-EVK-001
This evaluation board has provided the secondary-side synchronous rectification circuit using BM1R00147F. This evaluation board assumes that the primary side controller of insulated type with PWM flyback converter operates in DCM and set to 5V for output voltage. The secondary-side MOSFET uses ROHM’s RX1L16BGN. The secondary-side MOSFET can be located on High Side. (When the secondary-side MOSFET is located on Low Side, see “User’s Guide BM1R00147F-EVK-002 (No.60UG023E)”.)
