TPS62866: Question about TPS62866

Part Number: TPS62866

Tool/software:

Hi Team,

I am working on the promoting TPS62866 for my customer on their power supply oppty, could you please help to share comments on below questions? Thanks.

1. Do we have output current accuracy for VOUT=0.75V, under PFM mode?

2. Load Transient：Iout=0.05A ⮂ 4A，What is the current slew rate？

3. Could you help to generate a load transient simulation on the following conditions? Vin=3.8V，Vout=0.75V，Iout= 0.01A ⮂ 4.0A, 1A/us，Auto PFM/PWM

4. Could you help to generate a line transient simulation on the following conditions? Vin=2.5V ⮂ 4.5V，60mV/us，Vout=0.75V，Iout=0A / 0.1A / 1.0A / 5.0A

Thanks.

BR.

hi Frank,

Thanks for using e2e.

I will try to find the data.

Just want to be clear, do you want to have the load transient performance from bench measurements or from Pspice simulations?

Thank you and best regards,

Jingyi

Hi Jingyi,

If you can have a bench measurement that would highly appreciated, thanks.

Hi Frank,

Got it. I will try to do the bench measurements then.

Best regards,

Hi Frank,

Please find the data in the attached pdf file. May I know which customer and EE you're supporting, and what is their expectation for the line transient performance?

Thank you and best regards,
