DC/DC Converter
A_T-W2 Series
0.25W, Fixed input voltage, isolated & unregulated
dual output
Patent Protection RoHS
FEATURES
z Operating temperature range: -40℃～+85℃
z Good temperature characteristic
z Isolation voltage: 1K VDC
z SMD package
z Internal surface mounted design
z International standard pin-out
A_T-W2 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.
