Part Number: TPS61087-Q1

Dear team,

According to the equation 9 in the datasheet, Rcomp=88k. My customer finally choose 100k & 820pF< is it ok?

Thanks & Best Regards,

Sherry

Hi Sherry,

1. It depends. Note that when you calculate the compensation network you need to use effective output capacitance. If you have RCOMP < 120 kΩ and CCOMP> 820 pF you can recommend the parameters to customer.

2. It seems that there are may output capacitors. Make sure customer really need them.
