1S7A_R Series

DC-DC Converter

1 Watt

The 1S7A Series is specially designed for applications where a single

power supply is highly isolated from the input power supply in a distri-

buted power supply system on a circuit board.

These products apply to:

1) Where the voltage of the input power supply is fixed

(voltage variation ≤±5%);

2) Where isolation is necessary between input and output

(isolation voltage ≤1000VDC);

3) Where the regulation of the output voltage and the output ripple

and noise are demanded.

1W Single Output - Fixed Input - Isolated & Regulated

Note:

1. Operation under minimum load will not damage the converter; However, they

may not meet all specification listed, and that will reduce the life of product.

2. All specifications measured at Ta=25°C, humidity<75%, nominal input voltage

and rated output load unless otherwise specified.

3. In this datasheet, all the test methods of indications are based on corporate

standards.

4. Only typical models listed, other models may be different, please contact our

technical person for more details.
