Power Management ICs Forum Discussions

Hi all,

We confirmed that the protection function works by changing the overvoltage setting value through PMBus in steady state.

So I have a question.

Please tell me how to actually operate the overvoltage without changing the overvoltage setting value through PMBus in steady state.

Best regards,

Dear experts.

Is it possible to get the simulation file about XDPS2201, I would like to see the effect on Cr when I change Cr's value

I am new to the PowIR Build tool, I need to understand how to set the output voltage for IRPS5401, I have done required configuration based on my requirement when I create a new device and I have all input voltages, output voltages, etc. for SWA, SWB, SWC, SWD, LDO I have created a pcd file, but I want desired output to be written into the register not into the OTP .

Before writing/testing with config file I want to understand the tool, with default values when i2c is detected how to write value into the register and read. 

If someone could point me the procedure of writing into the register it would be helpful for me to understand the tool by providing any source code or detailed pdf (Guide)

Thanks & Regards

Hello everyone , 

I want to use the IRPS5401 PMIC into one of my project to get multiple output rails of different voltages . The input power supply available for IRPS5401 PMIC is only 5V , but according to its data sheet the V supply pin needs 6V- 14V for , is there any way I could give it only 5V and run the IC efficiently or what if I put it NC ?  

Hoping to get some real quick responses. 

Hi all,

We are evaluating EVAL_TDA38740_3.3VOUT.

Since the transient response is not shown in the User manual for TDA38740 evaluation board, we measured it on the demo board.

Please check the attached file for the measurement circuit, register settings, and measurement conditions.

Is the transient response at 3.3V reasonable?

Please let us know how we can improve it further.

We changed the output voltage to 0.5V, 4.6V by VOUT_COMMAND.

Please let us know if there is any way to improve the transient response.

The parts on the board remain unchanged.

Best regards,
MS
