2:1 Wide Input Range Regulated Converter 2W In Compact SMD Package To +85°C Operating Temperature @ Full Load high 3kVDC/1 Second (1kVAC/1 Minute) Basic Isolation Continuous Short Circuit Protection IEC/EN62368-1 Certified (CB Scheme)
The a 2W, open-frame, SMD, isolated DC/DC converter with 2:1 input voltage range. It is available with 24V (18-36V) inputs and offers a single 5V output which is short circuit protected. The output is tightly regulated with less than 50mV output ripple. There is no minimum load requirement. The operating temperature to 100°C (with derating). Isolation is 3kVDC/1kVAC (Basic Isolation) and a control pin is fitted as standard. The converter is IEC/EN62368-1 certified and is 10/10 RoHS-conform. Class B EMC conformity can be reached with a simple external LC filter.

Notes: Note1: Efficiency is tested at nominal input and full load at +25°C ambient. Note2: Max. cap. load is tested at minimum input and full resistive load.
Notes: Note3: without suffix, standard tray packaging add suffix ,,-R" for Tape and Reel packaging Ordering Examples:
= nom.Vin=5VDC, nom. Vout= 5VDC, standard 3kVDC/1 second isolation, tray packaging = nom.Vin= 24DC, nom. Vout= 5VDC, standard 3kVDC/1 second isolation, tape and reel packaging

Notes: Note5: An input fuse is required if the main supply is not over-current protected. Recommended fuse: T2A slow blow type Note6: An external input filter capacitor is required if the model has to meet EN6100-4-4 and EN61000-4-5 Recom suggested: Nippon chemi-con KY Series, 220µF/100V ESR 48mW Note7: Customers are allowed to test once with 1kVAC/1 minute in their production. Thereafter the test voltage and time must be reduced for any repeat testing
