Datasheet
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.
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
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.
