APPLICATIONS
The A_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:
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.
