APPLICATION
The B_S-1WR3 series are specially designed for applications where a low power supply voltage has to be derived from a fixed bus voltage
The B_S-1WR3 series are suitable for use where
a) Where the voltage of the input power supply is fixed (voltage variation < ±10%);
b) Where isolation is required between input and output (isolation voltage <1500VDC);
c) Where the regulation of the output voltage is not critical
Typical applications include digital circuits, low frequency analog circuits, and IGBT drive circuits
