General Description
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.
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
 Circuit Current (No Switching):
800µA(Typ)
 Circuit Current (Auto Shutdown) : 120µA (Typ)
 DRAIN Terminal Absolute Voltage:
120V
 Operating Temperature Range: -40°C to +105°C
Package
W(Typ) x D(Typ) x H(Max)
5.00mm x 6.20mm x 1.71mm
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.
