Hi Team,
I would like to use our TLVM13660 to replace the LTM8064 in TEC solution. Please see the diagram below. Customer uses 2* LTM8064 to change the current direction. Could our TLVM13660 work in this application? Do you have other suggestion in this?
Thanks a lot

Hi Matthew,
The TLVM13660 and TPSM63606 are not designed to sink current on a steady-state basis. However, the LTM8064 shouldn't either (it's a buck module). Can you provide more detail on the application?

Hi Tim,
Thank you for your reply.
The TEC is refer to Thermo Electric Cooler, which is usually power by DC. It will be a cooler or heater depends on the direction of the current. So customer use 2*LTM8064 (Vin is 24V) as the supply. By making the output voltage of one LTM8064 5V higher than the other one, the current direction will be changed. Also LTM8064 has the Source and Sink current output current feature so it could be configured like above picture.
So i wonder to know if our buck module can support this application.
Thanks a lot

Hi Matthew,
I doubt the TLVM can sink current in steady stage (i.e. operate in reverse as a boost regulator). I see the LT module has the 2-quadrant operation feature.

Hi Tim,
How about TPSM63606? Do you have some suggestions on the buck module that can support this?

The TPSM63606 behaves the same. These weren't designed for sinking capability.
