B0503T-2W Datasheet, PDF (1/4 Pages) MORNSUN Science& Technology Ltd. – 2W, Fixed input voltage , isolated unregulated single output

DC/DC Converter
B_(X)T-2W series
2W, Fixed input voltage , isolated & unregulated single _FEATURES
output
l Miniature SMD package
l Isolation voltage: 1K VDC
l Operating temperature range: -40℃～+85℃
l Good temperature characteristic
l Internal surface mounted design
Patent Protection RoHS
l No External Component Required
l International standard pin-out
B_(X)T-2W 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 ≤1000VDC);
3.Where do not has high requirement of line regulation , load regulation and the ripple & noise of the output voltage;
Such as: pure digital circuits, low frequency analog circuits, and IGBT power device driving circuits.
