Hi,

Can you please help providing the step-by-step to enable the output voltage for IR38263 using PMBus? I'm trying to help a customer but as we don't have the eval-kit yet, we couldn't progress over a remote conference call.

We are using the PowIR GUI with USB005 dongle, the license is all set. By loading the default config file and selecting PVID mode the voltage is correct set and we can verify at the tool, thus the communication interface seems to be working, but when changing to PMBus and sending the commands, the output is always zero.

Can you please describe the procedures to modify and enable the output voltage using the GUI? We are probaly missing something.

If you have capability to provide some screenshots, probably it will help.

Hi 

we are looking a simple cost effective buck converter

Input DC Is +55VDC

output DC is 35VDC, load current at 35VDC is 3A.

can you suggest a cost effective simple solution.

Hello,

I am currently working with the REF WLCTX15WC evaluation board, and I am using the example source code from Modus Toolbox. I found the macro, CY_SOLN_QI_OVERRIDE_PD, in the config.h file. I was curious, can this macro be enabled in the main loop of the code? I'd like to disable USB C PD and enable DC on-the-fly if it's possible with this source code. Any help or information will be greatly appreciated.

Thank you!

I have 2 configurations for TLD7002-16 ES in ocfg file. one of them has values in GPIN0 (used to tail light function) and the second doesnt have values in GPIN0 (used for stop light function).

when i send the command DC_UPDATE to the PCB with values in GPIN0  i am able to turn on the LEDs. but when i send commands to the PCB with no values in GPIN0 any output is activated.

is possible that i need some command different o another procedure?

I am currently using ICE3PCS01G to design a circuit, the specifications are as follows: VIN_AC=85V～265V; Vout=312V; 300W; VCC=15V. At present, the test is not working properly. How do I analyze it when there is no voltage output at Vref? In addition, is there any document that can introduce how to calculate the resistance selection of the Vsense & Vovp circuit.
