DC/DC Converter
B_RN-1WR2 & B_RT-1WR2 series
1W, Fixed input voltage , isolated & unregulated single _FEATURES
output
l Compact size, ultra-thin package
l Continuous short circuit protection
l Isolation voltage: 1.5K VDC
l Operating temperature range: -40℃ to +105℃
Patent Protection RoHS
l Excellent temperature performance
l International standard pin-out
B_RN-1WR2 & B_RT-1WR2 series is specially designed for applications where an isolated voltage is required in a distributed power supply
system. It is suitable for
1.Where the voltage of the input power supply is stable (voltage variation: ±10%Vin);
2.Where isolation is necessary between input and output (isolation voltage ≤1500VDC);
3.Where do not has high requirement of line regulation and load regulation;
4.Such as: pure digital circuits, low frequency analog circuits, relay-driven circuits and data switching circuits.
