VRB3-DIP Series Dc-Dc Converter

Notes:

1. All specifications measured at TA=25 °C, humidity <75%, nominal input voltage and rated output load unless

otherwise specified.

2. See recommended circuits below for more details.

Applications:

The VRB3-DIP Series are specially designed for applications where wide range input voltage 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 wide range (voltage range: 2:1);

2) Where isolation is necessary between input and output (Isolation Voltage = 1500 Vdc)

3) Where the regulation of the output voltage and the output ripple noise are demanding.

These products don’t apply to:

1) Where the input voltage t is required to be more than 2:1;

2) Where the isolation voltage between input and output is required to be >1500VDC;

3) The output load’s actual power consumption is less than 1W.
