DC/DC Converter F_XT-1WR2 Series 1W, Fixed input voltage, isolated & unregulated single output Continuous short-circuit protection Operating temperature range: -40℃ to +105℃ High efficiency up to 80% SMD package Isolation voltage: 3K VDC Low ripple & noise International standard pin-out Patent Protection RoHS F_XT-1WR2 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. Selection Guide Input Voltage (VDC) Certification Efficiency (%,Min./Typ.) @ Full Load Output Voltage Output Current (mA)(Max./Min.)

DC/DC Converter F_XT-1WR2 Series Design Reference 1. Typical application circuit If it is required to further reduce input and output ripple, a filter capacitor may be connected to the input and output terminals, see Fig.3. Moreover, choosing a suitable filter capacitor is very important, start-up problems may be caused if the capacitance is too large. Under the condition of safe and reliable operation, the recommended capacitive load values are shown in Table 1.
