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

Circuit Current (No Switching):

Circuit Current (Auto Shutdown) :

DRAIN Terminal Absolute Voltage:

800µA(Typ)

120µA (Typ)

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

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.
