A common customer inquiry concerning the part appearance of the THM 10 (10W) Series DC DC converters from Traco Power is “Why are the part’s pinouts not the same as shown on the datasheet? There are two pins missing.”
According to the datasheet, the diagram “standard pinning” is indicating the positions of the pinout of the parts. The actual pin assignment should refer to the Pinout table for specific models, such as THM 10-2415, which is a Single Output Model. The positions of Pin11 and Pin15 are listed as “No pin”, which means this is a 5-pins package.
The Dual Output Model is 6-pins Package.
