Hi Support
customer would like to know the min feedback resistor value, the current usage is upper 31.6Kohm bottom is 10khom would like to change to upper 3.16kohm and bottom 1kohm
any side effect behind ?
thanks a lot

Hi Red,
It's not going to affect the device performance, but it will raise the current draw a little (for 3.3Vout, almost a milliamp), so the efficiency (and quiescent current) at light load will suffer a bit. There's no minimum value as such for the feedback resistors, but there's no advantage in going too low and it will burn current.
