General Description
Key Specifications
BM1R00146F-150F are synchronous rectification
controller to be used in the secondary-side output. It
has a built-in 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.
Input Voltage Range: 2.7V to 32V

120µA (Typ)
120V
Operating Temperature Range: -40°C to +105°C
Package

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.
