Product Overview
TMR 12-4813WI is a TMR 12WI series isolated 12W DC/DC converter module with regulated output, featuring wide 4:1 input voltage range. The product offers a very high power density of 4.73W/cm³ in an ultra-compact SIP-8 metal package occupying only 2.0cm² (0.3 square inch) of board space. An excellent efficiency allows for an extended operating temperature range of -40° to +65°C without derating under natural convection conditions. Further features include remote on/Off control, continuous short circuit protection and an I/O isolation voltage of 1600V DC. The very compact dimension of this converter makes it an ideal solution for many space critical applications in communication equipment, instrumentation and industrial electronics.
