Low Consumption and High Accuracy Shunt Regulator Built-in

High Efficiency and Low Standby Power,

CCM corresponding

Secondary Side Synchronous Rectification

Controller IC

BM1R00xxxF

General Description

BM1R00xxxF 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.

BM1R00xxxF 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.
