DC/DC Converter

B_S-1WR2 & B_D-1WR2 series

1W, Fixed input voltage, isolated & unregulated

single output

FEATURES

 Continuous short-circuit protection

 Operating temperature range: -40℃ to +105℃

 High efficiency up to 80%

 Compact SIP/DIP package

 International standard pin-out

 Isolation voltage: 1.5K VDC

 EN60950,UL60950,IEC60950 approval

CB Patent Protection RoHS

B_S-1WR2 & B-D-1WR2 series are specially designed for applications where an isolated voltage is required in a distributed power supply

system. They are suitable for

1. Where the voltage of the input power supply is stable (voltage variation: ±10%Vin);

2. Where isolation between input and output is necessary (isolation voltage ≤1500VDC);

3. Where the output voltage regulation and the ripple & noise of the output voltage is not strictly required;

4. Typical application: digit circuit condition; normal low-frequency artificial circuit condition; relay drive circuit and data switching circuit

condition, etc.
