Part Number: LP87561-Q1

Hello

When I using the lp87561-q1, I found that the power output was only 0.9v, but I want it to be 1.0v.

We need to write registers to output 1.0v.

1. May I ask whether TI supports the fixed output of the version 1.0v? Which channels are available?

2. If it is user development, do you have specific instructions to avoid OTP misoperation?

Thanks.

Hello,
I have passed your question to a product specialist to work with you on this.

Hello,

The released LP87561I has default 0.9V programmed to the OTP memory. If other voltage option is desired, it needs I2C control to the voltage registers or if special OTP revision of the device is required then I would suggest you contact your local TI sales representative for further discussion on the needs. Custom OTP version of the LP87561 will require business case review.

The user registers are not locked, if that is what you mean. So if the data written to the voltage register through I2C is corrupted the voltage output value can be wrong, there is no protection/lock/checksum etc. to prevent that.

Hope this helps!

Thanks.

hi，Tomi
I need the OTP version of the default 1.0V output. I will further contact with TI sales.
Does this DCDC have an OTP version of 1.0V output in mobileye's eyeQ4 solution application?(That's just what we need.)
Thank you very much!!
