F0505XT-W2R2 Datasheet, PDF (1/4 Pages) MORNSUN Science& Technology Ltd. – Continuous short-circuit protection

DC/DC Converter
F_XT-W2R2 Series
0.25W, Fixed input voltage, isolated & unregulated
single output
FEATURES
 Continuous short-circuit protection
 Operating temperature range: -40℃ to +105℃
 High efficiency up to 77%
 Miniature SMD package
 Isolation voltage: 3K VDC
 International standard pin-out
Patent Protection RoHS
F_XT-W2R2 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 ≤3000VDC);
3. Where the output voltage regulation is not strictly required;
4. Typical application: preceding-stage interference isolation condition; ground-interference canceled condition; digit circuit condition;
Voltage-isolation converting condition; normal low-frequency artificial circuit condition; relay drive circuit condition, etc.
