Hi Team,
Recently my customer is designing the TPS62170.
Input: 4-16V. typ: 8V
output: 3.5V, Iout max: 0.3A.
Based on the webench design, I can get below design. for the feedback resistor, it suggested: 180k & 604k.
However, according to my customers design requirement, they cannot use the 100k ohm resistor or value above 100k.
So they'd like to check whether 20K & 68K can be used to replace the original design.
Their design is as below. (PG function is not required).
