Hi team,
I’ve got three questions on TPS7A87. Could you kindly take a look below?
Q1: The datasheet show VREF typical value (0.8V) only. Is there any data on MIN/MAX?
Q2: To make PG=High (pull-up), VFBx should be larger than VIT(PGx) + VHYS(PGx) according to the datasheet.
Expressed as a percentage of VOUTx(target), VIT(PGx) is 88.9% typ and VHYS(PGx) is 1% typ.
So in total VFBx should be larger than 89.9% of VOUTx(target), is my understanding correct?
Q3: There is VOUTx equation expressed with VREF on the bottom-left of Figure 41.
On the other hand, equation 1 of section 8.1.1.1 expressed VOUTx with VFBx.
Which one is correct?
If both equations are correct, then VREF=VFBx=0.8V typ ?
Best regards,
Kurumi
