APPLICATIONS
The H_LT-2W Series are specially designed for
applications where a group of polar power supplies
are isolated from the input power supply in a
distributed power supply system on a circuit board.
These products apply to:

2) Where isolation is necessary between input and
output (isolation voltage ≤6000VDC);

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.
