The TMR 12WI series is a family of isolated 12W DC/DC converter modules
with regulated output, featuring wide 4:1 input voltage ranges. The product offers a very high power density of 4.73W/cm³ in an ultra-compact SIP-8 metal
package occupying only 2.0 cm² (0.3 square inch) of board space. An excellent
efficiency of up to 90% allows for an extended operating temperature range of
–40° to +65°C without derating under natural convection conditions (see recommended PCB layout). Further features include remote On/Off control, continuous short circuit protection and an I/O isolation voltage of 1600 VDC. The
very compact dimensions of these converters make them an ideal solution for
many space critical applications in communication equipment, instrumentation
and industrial electronics.
