The TMR 4WI is a regulated 4 Watt DC/DC converter series with 4:1 input volt-

age range. It comes in a compact SIP-8 package featuring single and dual out-

put models, I/O isolation voltage of 1600 VDC and protection against short-cir-

cuit and over load. Being a 4 Watt converter this series acts as an excellent gap

closer between the more common 3 & 6 Watt converters. It offers a cost-effi-

cient alternative to 5 and 6 Watt converters in applications where a 3 Watt con-

verter would operate at the absolute technical limits (e.g. output power). The in-

telligent design provides efficiencies up to 83% and a temperature range of

-40°C to +70°C without derating which enables an unrestricted use of this

converter series in applications with demanding temperature requirements. Ad-

ditionally, the integrated remote On/Off function offers a convenient way to

control your application. Certified according to the latest IEC/EN/UL 62368-1

industrial standard the TMR 4WI is designed to deliver a high quality, cost effi-

cient and compact solution for many applications.
