Note
Isolated DC-DC Converters
IF_S-1W Series
1. Io below this value will not damage these converters, however, they may not meet all listed specifications.
2. Typical value, tested at nominal input and full load.
3. For each output.
4. Specifications subject to change without notice.
5. This series of products do not support CC mode, CR mode is recommended.
6. In case of long input lines or hot plug-in requirements, we recommended to use an external low ESR capacitor
(22uF) near to the converter’s input pins.

Line regulation:
Isolated DC-DC Converters
IF_S-1W Series
Narrow input voltage range（±10%）and unregulated output voltage series.
Line regulation=
Ä
Vout = Vout(+10%)-Vout(-10%) x100%
Vout
Vout(+10%)：Output voltage at Vin = 1.1xVin(nominal)&full load
Vout(-10%)：Output voltage at Vin = 0.9xVin(nominal)&full load
Vout：Output voltage at Vin = Vin(nominal)&full load
Ä
Vin = Vin(+10%)-Vin(-10%) x100%
Vin(nominal)
Vin(+10%)：Input voltage = 1.1xVin(nominal)
Vin(-10%)：Input voltage = 0.9xVin(nominal)

Load regulation :

Vout(FL)
Vout(FL): Output voltage at full load
Vout(NL): Output voltage at 25% full load or 10% full load
