DC/DC Converter TMR 4 Series, 4 Watt Compact SIP-8 package Wide 2:1 input voltage range Temperature range 40 to +70C without derating High efficiency up to 87% I/O isolation 1600 VDC UL 62368-1 IEC 62368-1 Protection against short-circuit and over The TMR 4 is a regulated 4 Watt DC/DC converter series with 2:1 input voltage load range. It comes in a compact SIP-8 package featuring single and dual output models, I/O isolation voltage of 1600 VDC and protection against short-circuit Fully regulated outputs and over load. Being a 4 Watt converter this series acts as an excellent gap Remote On/Off control 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- 3-year product warranty verter would operate at the absolute technical limits (e.g. output power). The in- telligent design provides efficiencies up to 87% and a temperature range of -40C to +70C 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 4 is designed to deliver a high quality, cost efficient and compact solution for many applications.
