DC-DC Converter

20 Watt

The 20DAWE_1.5 series are isolated 20W DC-DC products with a 2:1 input

voltage range. They feature efficiencies of up to 90%, 1500VDC input to

output isolation, operating ambient temperature range of -40°C ~ +85°C,

output short-circuit, over-voltage and over-current protection. They meet

CLASS A of CISPR32/EN55032 EMI standards without external compo-

nents.

They are widely used in applications such as data transmission device,

battery power supplies, tele-comunication device, distributed power

supply system, hybrid module system, remote control system, industrial

robot system fields.

Example:

20DAWE_2415S1.5

20 = 20Watt; D = DIP; A = series; W = wide input (2:1) 18-36Vin;

E = cost effective; 15Vout; S = single output; 1.5 = 1500VDC isolation
