LP87524J-Q1: Need to calculate the power losses of the device

Hello Priya,

If you want to calculate power dissipation then you could use device efficiency information in PEET-GUI here: https://dev.ti.com/gallery/view/PMIC/PMIC-Efficiency-Estimator-Tool/ver/0.9.5/ 

And device should be selected LP8756/52-Q1.

Hello Ishtiaque,

Thank you for giving the ready solution. but when I am doing the excel calculation then I am getting the different result. Excel calculation and Tool calculation results are getting varied. I am attaching excel calculation & PMIC efficiency estimator calculator results herewith for your review purpose. please let me know I am doing correct or using the wrong formulas.

Also, please correct me, if I am wrong.Power dissipation calculation - LP87524J-Q1.xlsx

Hi Priya,

I cannot look thoroughly the excel sheet at the moment. But just to let you know that efficiency measurements on PMIC Efficiency Estimator Tool are practical measurements done on the EVM board. So, definitively some delta can be expected from theoretical calculation but not significant difference though. If you really want to me to look then you need to wait until next week. However, you can rely on the results provided in Efficiency Tool.

Hello Ishtiaque,

I will go with this PMIC Efficiency Estimator Tool calculation. You take your time and check the attached excel calculation sheet. I need your comments on this.

Alright Thanks! Hope it helped in some way. I will try to get back to you once I have read that.
