Part Number: TPS22965

Hi

My customer will use TPS22965 the following condition.
They would like to calculate the ton but it is not written the formula or data at VBIAS=3.6V in datasheet.
Could you tell me the calculation method or  data under customer condition?

 Vin=1.8V or 2.5V
 VBIAS=3.6V 
 Ton=2500us 
 Cin=1uF
 CL=0,1uF
 RL=10Ω

Best regards,
Yokota

    Hi Yokota, 

    Thanks for reaching out on E2E!

    Looking at our characterization data, here is a rough estimate of the tON times for VBIAS = 3.3V. Unfortunately, we don't have results for VBIAS = 3.6V, but these values should be close to the expected results.

    tON (us) VBIAS : 3.3V
    CT (pf) 1.8V 2.5V
    0 203 216
    220 519 576
    470 822 934
    1000 1250 1440
    2200 2940 3490
    4700 6160 7300
    10000 12600 15000

    Thanks,

    Arthur Huang
