APPLICATIONS
The KRB2005MS-2W is specially
designed for applications where a wide
range input voltage power supplies a 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
demanding.
