Mechanical Drawing TSW1400

Other Parts Discussed in Thread: TSW3085EVM

Hello ,

exist  a mechanical Drawing from the TSW 1400EVM and the TSW3085EVM?. I want mount this parts with the Standoffs on a ALuminia Board.

In the document from the TSW 1400EVM  is described " First connect 5 V Power to the Board, then turn on the Switch SW7"

I want to build the TSW1400EVM , TSW3085EVM, a PC with a Display in a Case with a main power supply ( 5V, 6V, 12 V ) Is it possible to connect  all together with the Switch SW7 "On"  and then turn on all boards with the main power supply?

Thanks for an answer

best regards Martin

    Martin,

    The TSW1400EVM EVM tools page has design packages available for download. The package contains gerber file and odb file for you to extract the mechanical drawing in the fab page.

    I have uploaded the TSW3085EVM Gerber file and schematic in this post. We will update the TI web with the design package as well. 

    The TSW1400EVM has on-board 5Vinput, 6Voutput boost converter that may be controlled by SW7. The output of the 6V is connected to pins 1-4 of the J4 HSMC connector. When TSW3085EVM is connected to the TSW1400EVM, it is possible to route this 6V to the TSW3085EVM via the boost converter through the fuse. Refer to the TSW1400/TSW3085EVM schematic for detail.

    Please do measure the 6V input current for the TSW3085EVM under your operating condition and check all the connections prior to connecting all the boards. I believe the boost converter is limited to 1A output in the design (the 3A spec in the boost converter datasheet includes the ripple switching current going through the converter FET). This is to prevent damage to both boards if there are over-current.
