APPLICATIONS
The B_LT-2W Series are specially
designed for applications where a single
power supply is isolated from the input
power supply in a distributed power
supply system on a circuit board.
These products apply to:
1) Where the voltage of the input power
supply is fixed (voltage variation
≤±10%);
2) Where isolation is necessary
between input and output (isolation
voltage =1000VDC);
3) Where the regulation of the output
voltage and the output ripple noise
are not demanding.
Such as: purely digital circuits, ordinary
low frequency analog circuits, and IGBT
power device driving circuits.
