Hello,
I am working on LM5170 to use it as a Power Optimizer. Is there any recommended or dedicated MCU for LM5170 which I can plug on LM5170-EVM and use it for my application?
Thank you

Hi Jeet,
Thank you for your interest in LM5170.
We don't have special recommendation but as a reference, TMS320F is used in this reference design.

Hi Jeet,
The LM5170 EVM is a good starting point. You don't need an MCU to run the EVM. It has all the sensing, feedback and compensation on the board, all in analog, and can run in current mode bi-directional, and voltage mode buck and boost. For the guidance on the operation of the EVM, please check the user's guide https://www.ti.com/lit/pdf/snvu543.
Please let me know if there is any question.
Thanks,

Hello Yinsong,
I tried running LM5170EVM in boost mode without MCU.
I have shorted the two pads of circuit breaker on the bottom side.
My Low side power supply input voltage is 12V and have kept the power supply in CC mode with current set to 1A.
Output is a electronics load with resistance set to 100 ohms.
My Jumper settings:
J1 = Not connected
J2 = Connected
J3 = Connected
J4 = Connected
J5 = (2,3) connected
J6 = Not connected
J7 = Not connected
J8 = Not connected
J13 = not connected
J14, J15, J16, J19, J20, J22, J23, J24, J25, J26 = Not connected
J21 = (1,2) Connected
J27 = Connected
J28 = (2,3) connected
J29 = (1,2) connected
J30 = (2,3) connected
J31 = (1,2) connected
J32 = Not connected
J33 = Not connected
J34, J35, J36, J37 = Connected
I start my system with turning electronics load On and then Low side power supply On.
After, starting the system the input side current is 0 A. it seems the EVM is not responding.
May I know what changes are required.
While testing the system with electronic load under Constant current (0.2A) and increasing the input voltage to 13. The output voltage becomes 12.36 V with input and output current 0.2A.
Under Boost control operation the output voltage should be 50.5 V am I correct?
Hi Jeet,
Thank you for the update. Could you please check the voltage of COMP?
Thanks,
Yinsong
