The KRB_P Series are specially designed
for applications where a wide range input
voltage power supplies are non-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 wide range.
2) Where the regulation of the output voltage
and the output ripple noise are not
dem anding.
3) Where the regulation of the output voltage
and the output ripple noise are not
dem anding.
